Special Use Sensors - Weldable Strain GagesStandard Weldable PatternsMicro-Measurements For technical questions, contact: micro-measurements@Document Number: 11519Micro-Measurements Standard Weldable Strain Gages and Temperature Sensors are specially designed for spot welding to structures and components. They are ideal for applications where test or environmental conditions preclude clamping and curing an adhesively bonded gage installation.These gages are equally advantageous when strain measurements must be made at an elevated temperature,but the nature of the test object does not permit the use of an elevated-temperature-curing adhesive.Surface preparation requirements are minimal; only an appropriate solvent cleaning and abrasion of the test part surface with silicon-carbide paper or a small, hand-held grinder is needed. Spot welding is accomplished with a portable stored-energy hand-probe spot welder, such as the Model 700. Environmental protection is as easily applied to a welded gage installation as to an adhesively bonded gage.Refer to Instruction Bulletin B-131 and Catalog A-110 for further information on installation and protective coatings,and to Bulletin 302 for specifications on the Model 700Welding/Soldering Unit.DESCRIPTION AND PERFORMANCEGeneral — All sensors are laboratory-prebonded, with a high-performance adhesive, to thin (0.005 in [0.13 mm])metal carriers. Sensor grids are fully encapsulated for protection against handling and installation damage.Standard weldable strain gages are offered in two series to meet differing performance requirements. Both series are available in either 06 or 09 self-temperature compensation.Strain gages with 06 S-T-C have Inconel carriers, while S-T-C 09 gages and temperature sensors are mounted on 300-series stainless steel.CEA-Series Welda le Strain Gage —Polyimide-encapsulated constantan foil grid, with large, rugged,copper-coated tabs. In most cases, the carrier can be contoured to a radius as small as 1/2in [13mm]. The CEASeries is ideal for direct leadwire attachment, before or after installation.Strain range is ±5000µin/in [±5000µm/m], and normal operating temperature range is –100° to +200°F [–75° to +95°C]. Short-term maximum temperature is +300°F [+150°C].LWK-Series Weldab le Strain Gage — Nickel-chromium alloy grid, encapsulated in fiberglass-reinforced epoxy phenolic. The LWK gage is provided with a three-wire lead system with 10 in [250 mm] of Teflon ®-insulated leadwire.This construction simplifies leadwire temperature compensation and provides for easy connection of the lead system to the instrumentation cable. Minimum installation radius is generally limited to 2in [50 mm].Strain range is ±5000µin/in [±5000µm/m], and normal operating temperature range is –320° to +500°F [–195° to +260°C]. Short-term maximum temperature is +550°F [+290°C].WWT-Series Temperature Sensor — High-purity nickel foil grid encapsulated in fiberglass-reinforced epoxy-phenolic,and equipped with integral three-tab terminal to facilitate leadwire attachment. The temperature sensor is normally installed on a flat surface of the workpiece, but, in any case,should always be oriented with the gridlines in the direction of minimum strain to avoid strain-induced errors (see Micro-Measurements Tech Note TN-506, Bondable Resistance Temperature Sensors and Associated Circuitry).With an appropriate LST Matching Network, the temperature response characteristic of the nickel can be linearized and scaled for direct readout (in degrees) with any strain indicator.Teflon is a Registered Trademark of DuPont.MEASUREMENT CONSIDERATIONSIt is important to note that operating characteristics of weldable strain gages (gage factor, transverse sensitivity,and thermal output) are specified for the basic strain gage itself — without the metal carrier. Thus, the properties are measured by bonding a conventional strain gage directly to an appropriate calibration specimen, following standard methods specified for all Micro-Measurements strain gages. This procedure assures the most accurate results,independent of the variables introduced by welding. In particular, the user should be aware that the gage factor specified on the engineering data sheet accompanying the gage applies only to the basic strain gage, without the shim. The effective gage factor of the weldable assembly (after welding to the test member) is commonly 5 to 10%lower than this, due primarily to the stiffness of the shim.The reduction in gage factor is not subject to quantitative generalization, because it depends on the cross-sectional properties of the test specimen, and on the mode of loading (e.g., bending versus direct stress). It has been demonstrated, however, that for a group of like specimens, loaded in the same manner, the weldable gages exhibit very good repeatability and uniformity of response. Therefore, when test requirements dictate greatest accuracy, the weldable gages should be calibrated on a specimen of the same material and cross section as the test part, and under the same mode of loading.Special Use Sensors - Weldable Strain GagesStandard Weldable PatternsMicro-MeasurementsDocument Number: 11519For technical questions, contact: micro-measurements@Note 1: Products with designations and options shown in bold are not RoHS compliant.GAGE PATTERN AND DESIGNATIONInsert Desired S-T-C No. in Spaces Marked XX.See Note 1RES.IN OHMS.DIMENSIONSCARRIERACTIVE GRID MATRIX Length Width Thick Length Width Length Width CEA-XX-W250A-120CEA-XX-W250A-350120 ± 0.4%350 ± 0.4%0.630.340.0050.2300.1250.440.1716.08.60.135.843.1811.24.3Most flexible and conformable pattern.

Offset drift and gain drift are guaranteed to 1.2 μV/°C and 10 ppm/°C, respectively, for G = 1000. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 100 dB at G = 1000 from dc to 20 kHz. The combination of precision dc performance coupled with high speed capabilities makes the AD8253 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers.The AD8253 user interface consists of a parallel port that allows users to set the gain in one of two different ways (see Figure 1 for the functional block diagram). A 2-bit word sent via a bus can be latched using the WR input. An alternative is to use transparent gain mode, where the state of logic levels at the gain port determines the gain.FUNCTIONAL BLOCK DIAGRAMS S+IN6983-1Figure 1.8070605040302010–10–201k10k100k1M10M100MFREQUENCY (Hz)GAIN(dB)6983-23Figure 2.

For performance to +125°C, see the Typical Performance Characteristics section.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operationalsection of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.MAXIMUM POWER DISSIPATIONThe maximum safe power dissipation in the AD8253 package is limited by the associated rise in junction temperature (T J ) on the die. The plastic encapsulating the die locally reaches the junction temperature. At approximately 140°C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit can change the stresses that the package exerts on the die, permanently shifting the parametric performance of the AD8253. Exceeding a junction temperature of 140°C for an extended period can result in changes in silicon devices, potentially causing failure. The still-air thermal properties of the package and PCB (θJA ), the ambient temperature (T A ), and the total power dissipated in the package (P D ) determine the junction temperature of the die. The junction temperature is calculated as()JA D A J θP T T ×+=The power dissipated in the package (P D ) is the sum of the quiescent power dissipation and the power dissipated in the package due to the load drive for all outputs. The quiescent power is the voltage between the supply pins (V S ) times the quiescent current (I S ). Assuming the load (R L ) is referenced tomidsupply, the total drive power is V S /2 × I OUT , some of which isdissipated in the package and some of which is dissipated in theload (V OUT × I OUT ). The difference between the total drive power and the load power is the drive power dissipated in the package.P D = Quiescent Power + (Total Drive Power − Load Power )()L 2OUT L OUTS S S D R V –R V2V I V P ⎟⎟⎠⎞⎜⎜⎝⎛×+×= In single-supply operation with R L referenced to −V S , the worstcase is V OUT = V S /2.Airflow increases heat dissipation, effectively reducing θJA . In addition, more metal directly in contact with the package leads from metal traces through holes, ground, and power planes reduces the θJA .Figure 4 shows the maximum safe power dissipation in the package vs. the ambient temperature on a 4-layer JEDEC standard board.2.001.751.501.251.000.750.500.250–40–20120100806040200M A X I M U M P O W E R D I S S I P A T I O N (W )AMBIENT TEMPERATURE (°C)06983-004Figure 4.

Simplified SchematicTransparent Gain ModeThe AD8253 is a monolithic instrumentation amplifier based on the classic 3-op-amp topology, as shown in Figure 51. It is fabricated on the Analog Devices, Inc., proprietary i CMOS® process that provides precision linear performance and a robust digital interface. A parallel interface allows users to digitally program gains of 1, 10, 100, and 1000. Gain control is achieved by switching resistors in an internal precision resistor array (as shown in Figure 51).The easiest way to set the gain is to program it directly via a logic high or logic low voltage applied to A0 and A1. Figure 52 shows an example of this gain setting method, referred to through-out the data sheet as transparent gain mode. Tie WR to the negative supply to engage transparent gain mode. In this mode, any change in voltage applied to A0 and A1 from logic low to logic high, or vice versa, immediately results in a gain change. is the truth table for transparent gain mode, and shows the AD8253 configured in transparent gain mode.Table 5Figure 52All internal amplifiers employ distortion cancellation circuitry and achieve high linearity and ultralow THD. Laser-trimmed resistors allow for a maximum gain error of less than 0.03% for G = 1 and a minimum CMRR of 100 dB for G = 1000. A pinout optimized for high CMRR over frequency enables the AD8253 to offer a guaranteed minimum CMRR over frequency of 80 dB at 20 kHz (G = 1). The balanced input reduces the parasitics that in the past had adversely affected CMRR performance.NOTE:1. IN TRANSPARENT GAIN MODE, WR IS TIED TO −V S .THE VOLTAGE LEVELS ON A0 AND A1 DETERMINE THE GAIN. IN THIS EXAMPLE, BOTH A0 AND A1 ARE SET TO LOGIC HIGH, RESULTING IN A GAIN OF 1000.06983-051GAIN SELECTIONThis section describes how to configure the AD8253 for basic operation. Logic low and logic high voltage limits are listed in the Specifications section. Typically, logic low is 0 V and logic high is 5 V; both voltages are measured with respect to DGND. Refer to the specifications table (Table 2) for the permissible voltage range of DGND. The gain of the AD8253 can be set using two methods: transparent gain mode and latched gain mode. Regardless of the mode, pull-up or pull-down resistors should be used to provide a well-defined voltage at the A0 and A1 pins.Figure 52. Transparent Gain Mode, A0 and A1 = High, G = 1000Latched Gain ModeSome applications have multiple programmable devices such as multiplexers or other programmable gain instrumentation amplifiers on the same PCB. In such cases, devices can share a data bus. The gain of the AD8253 can be set using WR as a latch, allowing other devices to share A0 and A1. shows a schematic using this method, known as latched gain mode. The AD8253 is in this mode when Figure 53WR is held at logic high or logic low, typically 5 V and 0 V , respectively. The voltages on A0 and A1 are read on the downward edge of the WR signal as it transitions from logic high to logic low. This latches in the logic levels on A0 and A1, resulting in a gain change. See the truth table listing in for more on these gain changes.Table 6NOTE:FROM LOGIC HIGH TO LOGIC LOW, THE VOLTAGES ON A0AND A1 ARE READ AND LATCHED IN, RESULTING IN AGAIN CHANGE. IN THIS EXAMPLE, THE GAIN SWITCHES TO G = 1000.06983-052Figure 53. Latched Gain Mode, G = 10001X = don’t care.On power-up, the AD8253 defaults to a gain of 1 when inlatched gain mode. In contrast, if the AD8253 is configured in transparent gain mode, it starts at the gain indicated by the voltage levels on A0 and A1 on power-up.Timing for Latched Gain ModeIn latched gain mode, logic levels at A0 and A1 must be held for a minimum setup time, t SU , before the downward edge of WR latches in the gain. Similarly, they must be held for a minimum hold time, t HD , after the downward edge of WR to ensure that the gain is latched in correctly. After t HD , A0 and A1 may change logic levels, but the gain does not change until the next downward edge of WR . The minimum duration that WR can be held high is t -HIGH , and t -LOW is the minimum duration that WR can be held low. Digital timing specifications are listed in The time required for a gain change is dominated by the settling time of the amplifier. A timing diagram is shown in . Table 2.Figure 54When sharing a data bus with other devices, logic levels applied to those devices can potentially feed through to the output of the AD8253. Feedthrough can be minimized by decreasing the edge rate of the logic signals. Furthermore, careful layout of the PCB also reduces coupling between the digital and analog portions of the board.A0, A106983-053Figure 54. Timing Diagram for Latched Gain ModePOWER SUPPLY REGULATION AND BYPASSINGThe AD8253 has high PSRR. However, for optimal performance, a stable dc voltage should be used to power the instrumentation amplifier. Noise on the supply pins can adversely affect per-formance. As in all linear circuits, bypass capacitors must be used to decouple the amplifier.Place a 0.1 μF capacitor close to each supply pin. A 10 μF tantalum capacitor can be used farther away from the part (see Figure 55) and, in most cases, it can be shared by other precision integrated circuits.06983-054Figure 55. Supply Decoupling, REF, and Output Referred to GroundINPUT BIAS CURRENT RETURN PATHThe AD8253 input bias current must have a return path to its local analog ground. When the source, such as a thermocouple, cannot provide a return current path, one should be created (see Figure 56).THERMOCOUPLE+V –V SCAPACITIVELY COUPLED +V SREFCC–V SAD8253TRANSFORMER+V SREF–V SAD8253INCORRECTCAPACITIVELY COUPLEDf HIGH-PASS THERMOCOUPLE+V TRANSFORMER–V SCORRECT06983-055Figure 56. Creating an I BIAS PathINPUT PROTECTIONAll terminals of the AD8253 are protected against ESD. An external resistor should be used in series with each of the inputs to limit current for voltages greater than 0.5 V beyond either supply rail. In such a case, the AD8253 safely handles a continuous 6 mA current at room temperature. For applications where the AD8253 encounters extreme overload voltages, external series resistors and low leakage diode clamps such as BAV199Ls, FJH1100s, or SP720s should be used.REFERENCE TERMINALThe reference terminal, REF, is at one end of a 10 kΩ resistor (see Figure 51). The instrumentation amplifier output is referenced to the voltage on the REF terminal; this is useful when the output signal needs to be offset to voltages other than its local analog ground. For example, a voltage source can be tied to the REF pin to level shift the output so that the AD8253 can interface with a single-supply ADC. The allowable reference voltage range is a function of the gain, common-mode input, and supply voltages. The REF pin should not exceed either +V S or −V S by more than 0.5 V .For best performance, especially in cases where the output is not measured with respect to the REF terminal, source imped-ance to the REF terminal should be kept low because parasiticresistance can adversely affect CMRR and gain accuracy.INCORRECTCORRECT06983-056Figure 57. Driving the Reference PinCOMMON-MODE INPUT VOLTAGE RANGEThe 3-op-amp architecture of the AD8253 applies gain and then removes the common-mode voltage. Therefore, internal nodes in the AD8253 experience a combination of both the gained signal and the common-mode signal. This combined signal can be limited by the voltage supplies even when the individual input and output signals are not. Figure 28 and Figure 29 show the allowable common-mode input voltage ranges for various output voltages, supply voltages, and gains.LAYOUTGroundingIn mixed-signal circuits, low level analog signals need to be isolated from the noisy digital environment. Designing with the AD8253 is no exception. Its supply voltages are referenced to an analog ground. Its digital circuit is referenced to a digital ground. Although it is convenient to tie both grounds to a single ground plane, the current traveling through the ground wires and PC board can cause an error. Therefore, use separate analog and digital ground planes. Only at one point, star ground, should analog and digital ground meet.The output voltage of the AD8253 develops with respect to the potential on the reference terminal. Take care to tie REF to the appropriate local analog ground or to connect it to a voltage that is referenced to the local analog ground.Coupling NoiseTo prevent coupling noise onto the AD8253, follow these guidelines: • Do not run digital lines under the device.• Run the analog ground plane under the AD8253.•Shield fast-switching signals with digital ground to avoid radiating noise to other sections of the board, and never run them near analog signal paths.• Avoid crossover of digital and analog signals.• Connect digital and analog ground at one point only (typically under the ADC).•Power supply lines should use large traces to ensure a low impedance path. Decoupling is necessary; follow the guidelines listed in the Power Supply Regulation and Bypassing section.Common-Mode RejectionThe AD8253 has high CMRR over frequency, giving it greater immunity to disturbances, such as line noise and its associated harmonics, in contrast to typical in amps whose CMRR falls off around 200 Hz. They often need common-mode filters at the inputs to compensate for this shortcoming. The AD8253 is able to reject CMRR over a greater frequency range, reducing the need for input common-mode filtering.Careful board layout maximizes system performance. T o maintain high CMRR over frequency, lay out the input traces symmetrically. Ensure that the traces maintain resistive and capacitive balance; this holds for additional PCB metal layers under the input pins and traces. Source resistance and capacitance should be placed as close to the inputs as possible. Should a trace cross the inputs (from another layer), it should be routed perpendicular to the input traces.RF INTERFERENCERF rectification is often a problem when amplifiers are used in applications where there are strong RF signals. The disturbance can appear as a small dc offset voltage. High frequency signals can be filtered with a low-pass RC network placed at the input of the instrumentation amplifier, as shown in Figure 58. The filter limits the input signal bandwidth according to the following relationship:)C C (R 1FilterFreq C D DIFF +=2π2CCM RC 1FilterFreq π2=where C D ≥ 10 C C .。

Like the AD847, it provides highspeed, low power performance at low cost. The AD827 achieves a 300 V/µs slew rate and 50 MHz unity-gain bandwidth while consuming only 100 mW when operating from ±5 volt power supplies. Performance is specified for operation using ±5 V to ±15 V power supplies.The AD827 offers an open-loop gain of 3,500 V/V into 500 Ωloads. It also features a low input voltage noise of 15 nV/√Hz ,and a low input offset voltage of 2 mV maximum. Common-mode rejection ratio is a minimum of 80 dB. Power supply rejection ratio is maintained at better than 20 dB with input frequencies as high as 1 MHz, thus minimizing noise feedthrough from switching power supplies.The AD827 is also ideal for use in demanding video applica-tions, driving coaxial cables with less than 0.04% differential gain and 0.19° differential phase errors for 643 mV p-p into a 75 Ω reverse terminated cable.The AD827 is also useful in multichannel, high speed data conversion systems where its fast (120 ns to 0.1%) settling time is of importance. In such applications, the AD827 serves as an input buffer for 8-bit to 10-bit A/D converters and as an output amplifier for high speed D/A converters.APPLICATION HIGHLIGHTS1.

C–7–VIDEO LINE DRIVERThe AD827 functions very well as a low cost, high speed line driver for either terminated or unterminated cables. Figure 23shows the AD827 driving a doubly terminated cable in a follower configuration.+V V OUTFigure 23.A Video Line DriverThe termination resistor, R T , (when equal to the cable’scharacteristic impedance) minimizes reflections from the far end of the cable. While operating from ±5 V supplies, the AD827maintains a typical slew rate of 200 V/µs, which means it can drive a ±1 V, 30 MHz signal into a terminated cable.Table I.Video Line Driver Performance SummaryOver-V IN *V SUPPLY C C –3 dB B W shoot 0 dB or ±500 mV Step ±1520 pF 23 MHz 4%0 dB or ±500 mV Step ±1515 pF 21 MHz 0%0 dB or ±500 mV Step ±150 pF 13 MHz 0%0 dB or ±500 mV Step ±520 pF 18 MHz 2%0 dB or ±500 mV Step ±515 pF 16 MHz 0%0 dB or ±500 mV Step±50pF11 MHz0%*–3 dB bandwidth numbers are for the 0 dBm signal input.

C–8–multipliers connected in series. They could also be placed in parallel with an increase in bandwidth and a reduction in gain.The gain of the circuit is controlled by V X , which can range from 0 to 3 V dc. Measurements show that this circuit easily supplies 2 V p-p into a 100 Ω load while operating from ±5 V supplies. The overall bandwidth of the circuit is approximately 7 MHz with 0.5 dB of peaking.Each half of the AD827 serves as an I/V converter and converts the output current of one of the two multipliers in the AD539into an output voltage. Each of the AD539’s two multipliers contains two internal 6 k Ω feedback resistors; one is connectedbetween the CH1 output and Z1, the other between the CH1output and W1. Likewise, in the CH2 multiplier, one of the feedback resistors is connected between CH2 and Z2 and the other is connected between CH2 and Z2. In Figure 25, Z1 and W1 are tied together, as are Z2 and W2, providing a 3 k Ωfeedback resistor for the op amp. The 2 pF capacitors connected between the AD539’s W1 and CH1 and W2 and CH2 pins are in parallel with the feedback resistors and thus reduce peaking in the VCA’s frequency response. Increasing the values of C3and C4 can further reduce the peaking at the expense ofreduced bandwidth. The 1.25 mA full-scale output current of the AD539 and the 3 k Ω feedback resistor set the full-scale output voltage of each multiplier at 3.25 V p-p.Current limiting in the AD827 (typically 30 mA) limits the out-put voltage in this application to about 3 V p-p across a 100Ωload. Driving a 50 Ω reverse-terminated load divides this value by two, limiting the maximum signal delivered to a 50Ω load to about 1.5 V p-p, which suffices for video signal levels. The dynamic range of this circuit is approximately 55dB and is primarily limited by feedthrough at low input levels and by the maximum output voltage at high levels.Guidelines for Grounding and BypassingWhen designing practical high frequency circuits using the AD827,some special precautions are in order. Both short interconnection leads and a large ground plane are needed whenever possible to provide low resistance, low inductance circuit paths. One should remember to minimize the effects of capacitive couplingbetween circuits. Furthermore, IC sockets should be avoided.Feedback resistors should be of a low enough value that the time constant formed with stray circuit capacitances at the amplifier summing junction will not limit circuit performance.As a rule of thumb, use feedback resistor values that are less than 5 k Ω. If a larger resistor value is necessary, a small (<10pF)feedback capacitor in parallel with the feedback resistor may be used. The use of 0.1 µF ceramic disc capacitors is recommended for bypassing the op amp’s power supply leads.A TWO-CHIP VOLTAGE-CONTROLLED AMPLIFIER (VCA) WITH EXPONENTIAL RESPONSEVoltage-controlled amplifiers are often used as building blocks in automatic gain control systems. Figure 25 shows a two-chip VCA built using the AD827 and the AD539, a dual, current-output multiplier.

Failure to do so may result in electric shock.Do not use panels other than ones with the designated thickness and dimensions. Remove all burrs from the cutout before installing the Switch. Otherwise, the Switch may malfunction.Do not impose excessive force on the Switch at the time of panel-mounting.There are two small divots in the flange part of the case marking ON and OFF as shown in the following diagram. Use these marks as guides when mounting.WiringWhen soldering terminals manually, perform soldering within 3 s using a 60-W soldering iron (temperature at the tip of the soldering iron: 420°C max.). Do not apply excessive force to the terminals dur-ing soldering.When soldering using a soldering tub, perform soldering within 5 s in a soldering fluid at 270°C, or within 3 s in a soldering fluid at 350°C.Be sure that the wires are thick enough for the load (current) to be applied.Only A8L -@@-@5@@ models are equipped with (6.3×0.8) mm flat-quick connections for use with #187 fasten receptacles.The terminals of A8L -@@-@1@@ are not in compliance with IEC standards for flat-quick connections. Suitable for use as solder con-nection only.Using MicroloadsThe performance of the Switch may be affected if the Switch is used for switching micro loads. T est the Switch under the actual operating conditions.Operating EnvironmentDo not use the Switch in places with sulfide gas, corrosive gas, sea breeze, oil spray, or direct sunlight. Otherwise, the Switch may mal-function.Do not use the Switch in places that are visibly dusty. Otherwise, the contacts may fail to operate correctly.■CautionsT o increase the reliability of operation, test the Switch before actual operation.Be sure that there is an enough insulation distance between any Switch terminal and metal part.HandlingDo not drop the Switch. Otherwise, the Switch may malfunction.Do not impose excessive force on the Switch. Otherwise, the Switch may deform.The recommended panel material is SPCC. The Switch may fall off if the material is soft and cannot securely hold the Switch. When using a soft material, test the Switch with it before using the Switch in actual operation.Do not wire the Switch or touch any terminal of the Switch While power is being supplied.
