The device has exceptional stability for use in critical building performance applications with the popular versatility of our original Series MS2 Magnesense ® II transmitter. The MSX Pro simplifies the ordering process to deliver the desired configuration, which reduces product setup time. Pressure ranges of Pa, mm w.c., and in w.c. are available per device. All pressure ranges can be configured in unidirectional or bidirectional modes providing a total of 32 ranges. The MSX Pro transmitter can provide a linear pressure output or a linear velocity output with the square root extraction from the transmitter. Additional parameters have been included to expand the square root capability to calculate flow. Dual voltage and milliamp output signals can be used to provide control and equipment output signal verification.INSTALLATION Surface Mounting:Mount the transmitter on a vertical surface. The pressure sensor measurement is unaffected by orientation, but it is recommended the unit be mounted with the connections facing down to prevent moisture from entering either the pressure ports or the electrical cable entry. Attach the mounting flange to a flat surface using #8 x 1/2˝ pan head sheet metal screws. Do not over tighten.Duct Mounting (Universal model required):Mount the transmitter away from fans, corners, heating and cooling coils and other equipment that will affect the measurement of the pressure.1. To mount the transmitter, drill a .562˝ (12.70 mm) diameter hole into the duct. 2. Screw duct probe into back of housing. Insert transmitter probe into the duct.3. Mark location of mounting holes on duct using mounting flange as template. Drill holes.4. Attach mounting flange to duct with #8 x 1/2˝ pan head sheet metal screws. Do not over tighten screws.5. Place the included cap on the exterior positive pressure port.The Universal model can also be used as a standard wall mount transmitter. In this mode, do not use the duct probe and plug the port on the backside of the transmitterwith the included plug.1-29/32[48.43]1-29/32[48.43]ELECTRICALThe MSX Pro transmitter utilizes a 2-wire 4-20 mA Current Output , or a 3-wire 0-5 V / 0-10 V Voltage Output . It is also capable of Simultaneous Current and Voltage Output . The power and signals interconnect via a removable European-style four conductor terminal block, or optionally, via the included tooless terminal block. 2-Wire 4-20 mA Current OutputThe connections to the transmitter are made through terminals VDC and COM on the terminal block as shown in Figure 1. The terminal block is removable and each of the terminals are labeled next to the terminal block on the circuit board. Polarity is indicated by VDC and COM. See Figure 1.The maximum receiver load resistance (RL) for a given power supply voltage (Vps) is defined by the formula: Shielded 2-wire cable is recommended for control loop wiring. Ground the shield at the power supply end only.The receiver may be connected to either the negative or positive side of the loop, whichever is most convenient. Should polarity of the transmitter or receiver be inadvertently reversed, the loop will not function properly but no damage will be done to the transmitter.The maximum length of connecting wire between the transmitter and the receiver is a function of wire size and receiver resistance. That portion of the total current loop resistance represented by the resistance of the connecting wires themselves should not exceed 10% of the receiver resistance. For extremely long runs (over 1,000 feet), it is desirable to select receivers with lower resistances in order to keep the size and cost of the connecting leads as low as possible. In installations where the connecting run is no more than 100 feet, you can use a connecting lead wire as small as No. 22 ga.Selection of using a DC or AC power supply is made via the terminal block. See Figure 2 for DC Wiring. See Figure 3 for AC Wiring.The terminal block is removable and each of the terminals are labeled next to the terminal block on the circuit board. Positive polarity is indicatedby VOUT. AC/DC selection is made via the terminal block. If the polarity of the transmitter is inadvertently reversed, the unit will not function properly, but no damage will be done to the transmitter.The minimum receiver load is 1 kΩ. The resistance due to the wire should be low compared to the receiver load resistance. While the voltage at the terminal block remains unchanged with a 10 mA current flow, resistive losses in the wiring do cause errors in the voltage delivered to the receiver. For a 1% accurate gage, the resistance of the wires should be less than 0.1% of the value of the receiver load resistance. This will keep the error caused by the current flow below 0.1%.The output across VOUT and COM will be either 0-5 V, 0-10 V depending on the DIP switch setting. See DIP Switch Settings Section for more information.DC POWER SUPPLY 10-36 VDCV A CV D CC O MV O U TCURRENT RECEIVER+--+DC POWER SUPPLY 17-36 VDCVOLTAGE RECEIVER-++-V A CV D CC O MV O U T AC POWER SUPPLY 21.6-33 VACVOLTAGE RECEIVERV A CV D CC O MV O U T -+DO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.

Pull the LCD directly away from the product to remove. Reinstall the LCD afterwiring is completed.Simultaneous Current and Voltage OutputThe terminal block is removable and each of the terminals is labeled underneath the terminal block on the circuit board. Positive polarity is indicated by VOUT. The VDC terminal and a DC power supply must be used for Simultaneous Current and Voltage Output. The voltage output and the power supply must have separate wire leads that are only joined at terminal 2 of the transmitter. Additional error may occur for the voltage output if a single wire is used or if the wires are joined at the power supply or receiver.For the current output, the maximum allowable loop resistance (wiring + receiver resistance) is dependent on the power supply. The maximum loop voltage drop must not reduce the transmitter voltage below 17 V. The maximum loop resistance (R MAX ) for a given power supply voltage (V PS ) can be calculated using the following equation:The equation uses 17.0 instead of 10.0 as seen in the equation earlier with Figure 1. This represents the minimum voltage supply which is higher on the simultaneous output configuration due to the requirements of the voltage outputs.Shielded 4-wire cable is recommended for control loop wiring. Ground the shield at the power supply end only. Should the polarity of the transmitter or receiver be inadvertently reversed, the unit will not function properly, but no damage will be done to the transmitter.For voltage outputs, the minimum receiver load is 1 kΩ. The resistance due to the wire should be low compared to the receiver load resistance. While the voltage at the terminal block remains unchanged with a 10 mA current flow, resistive losses in the wiring do cause errors in the voltage delivered to the receiver. For a 1% accurate gage, the resistance of the wires should be less than 0.1% of the value of the receiver load resistance. This will keep the error caused by the current flow below 0.1%.The output across VOUT and COM will be either 0-5 V or 0-10 V depending on the DIP switch setting. See DIP Switch Settings Section for more information.Power SupplyRefer to the following tables for the required supply rating.DIP SWITCH SETTINGSDIP switch settings are marked directly on the PCBA as shown in Figure 5.

DIP Switch 6 - Response Time SelectionDIP Switch 6 toggles to select the desired response time.• When the switch is in the OFF or down direction, the transmitter response time will be instantaneous.• When the switch is in the ON or up direction, the response time will be 3 seconds. DIP Switches 7 and 8 - Maximum Range Selection (Pressure)DIP switches 7 and 8 work as a pair to select the maximum range output of the transmitter. Use the tables below to navigate pressure range selection. Alternatively, if using the device for velocity and flow, proceed to the next section.DIP Switches 7 and 8 - Maximum Range Selection (Velocity/Flow)DIP switches 7 and 8 work as a pair to select the maximum range output of the transmitter. Use the tables below to navigate velocity and flow range selection. CALIBRATIONThe transmitter security feature must be unlocked before calibration is accessible. See Section Program Menu-Menu Access Security. There is a 3 second delay from the time the zero or span calibration buttons are released until the time that the change in calibration takes place. This delay is used to prevent stress related offsets on the lower ranges.Zero CalibrationThe zero calibration can be set by applying zero pressure to both of the pressure ports and pressing the zero button for 3 seconds. If the LCD display is present, the display will read ZERO and then sequence back to the home display.The span calibration function allows the pressure value to be adjusted so that the currently applied pressure is the maximum configured pressure. This will in turn set the maximum analog output at the set pressure. It is recommended that the ZERO function be applied before performing a span. Apply the maximum desired pressure to the device, press and hold span for 3 seconds. If the LCD display is present, SPAN is displayed. The span function will be processed 3 seconds after the span button is released.For a positive span, apply pressure to the positive “+” port.LCD DISPLAYThe LCD comes with a housing cover, which contains a window. The display plugs into the pins on top of the circuit board. The LCD is 180° rotatable so that it will read properly if the device must be mounted with the connections facing up.The following error messages will appear if an LCD is present and the device is an error state.PROGRAM MENUHome MenuDuring normal operation, the display will be in the Home Menu and will display the current measured pressure and the engineering units.Menu Access SecurityBy default, a PIN code is not required to enter the configuration menus. However, if access to the menus needs to be restricted, follow the steps below.1. While in the Home Menu, press and hold the Zero and Span buttons until “PIN” is displayed.2. Press and hold the Zero and Span buttons until the current PIN setting isdisplayed (default is 0000).3. Use the Zero button to increment the selected digit (denoted by the caron ) orpress the Span button to select the next digit to the right.4. Any value between 0001 and 9999 will result in the requirement to enter the PINeach time the menu is entered. The value 0000 will disable the PIN entryrequirement.5. Press and hold the Span button until the next menu is displayed. PIN security setup is now complete.MAINTENANCE/REPAIRUpon final installation of the Series MSX Pro, no routine maintenance is required.

Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire.For signal wiring (the wiring between interconnected detectors and modules), it is recommended that the wiring be no smaller than 18 A WG (0.823 mm²). Wire sizes up to 12 A WG (3.31 mm²) may be used with the base.Alarm system control panels have specifications for allowable loop resistance. Consult the control panel specifications for the total loop resistance allowed before wiring the detector loops.Make wiring connections by stripping about 3/8" (10 mm) of insulation from the wire end (use strip gauge molded in base). Then slide the wire under the clamping plate and tighten the clamping plate screw. Do not loop the wire under the clamping plate. (See Figure 3.)Check the zone wiring of all bases in the system before installing the detec-tors. This includes checking the wiring for continuity, correct polarity, ground fault testing and performing a dielectric test.The base includes an area for recording the zone, address, and type of detec-tor to be installed at that location. This information is useful for setting the detector head address and for verification of the detector type required for that location.Once all detector bases have been wired and mounted, and the loop wiring has been checked, the detector heads may be installed in the bases.

气体传感器---压力传感器准确安装介绍
气体传感器压力传感器的安装很重要，如果安装的不正确，就会不能正工作，耽误时间和工作效率，如何正确的安装压力传感器呢？下面就来介绍下。
通常高温熔体气体传感器压力传感器的损坏都是由于其安装位置不恰当而引起的，如果将气体传感器强行安装在过小的孔或形状不规则的孔中，就有可能造成气体传感器的震动膜受到冲击而损坏，选择合适的工具加工安装孔，有利于控制安装孔的尺寸，另外，合适的安装扭矩有利于形成良好的密封，但是如果安装扭矩过高就容易引起高温熔体压力气体传感器的滑脱，为防止这种现象发生，通常在传感器安装之前在其螺纹部分上涂抹防脱化合物。
通过适当的仪表，在普通大气压和标准温度条件下，核实压力传感器的频率反应值。
核实压力传感器的编码与相应的频率反应信号的正确性。
为了确定压力传感器的编号和具体安装位置，需按充气网的各个充气段来考虑。
压力传感器必须沿着线缆进行安装，最好安装在线缆接头处。
每条线缆的始端和末端分别安装1每条线缆的分支点应装1个，如果两个分支点相距较近(小于100 m)，可只装1个。
线缆敷设方式(架空、地下)改变处应装1个对无分支的线缆，因垒线的线缆程式一致，压力传感器的安装隔距不大干500m，并使其总数不少于4个。
为了便于确定压力传感器故障点，除在起点安装压力传感器外，距起点150~200m处，还要另外安装1个当然在设计中，一定要考虑经济与技术的因素，在不需要安装压力传感器的地方，则应不必安装。
如果安装孔的尺寸不合适，高温熔体压力传感器在安装过程中，其螺纹部分就很容易受到磨损，这不仅会影响设备的密封性能，而且使传感器不能充分发挥作用，甚至还可能产生安全隐患。
只有合适的安装孔才能够避免螺纹的磨损(螺纹工业标准1/2-20UNF2B)，通常可以采用安装孔测量仪对安装孔进行检测，以做出适当的调整。
以上就是正确安装压力传感器的方法，希望你能学会哦！！。
Series 668 差压传感器规格与安装操作指南（Bulletin A-30-668）说明书
Series 668 Differential Pressure TransmitterSpecifications - Installation and Operating InstructionsBulletin A-30-668Ø5/32 [3.97]Our low cost Series 668 Differential Pressure Transmitter is capable of measuring low pressures with a ±1% accuracy ideally suited for proper building pressurization and air flow control. Transmitters can withstand up to 10 psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Compact, lightweight design makes installation simple and easy. Units also feature reverse-polarity protection.INSTALLATION MountingThe 668 Series is designed for mounting in either a switch box or by using the two (2) holes that are provided on the housing. Optimum performance is obtained by isolating the instrument from vibration and providing relatively clean, dry ambient air to the pressure ports. In most cases, preferred installation is withthe baseplate mounted vertically and located on a relatively flat surface in a junction box or attached to a nearby beam.CAUTION: The axis most sensitive to vibration is the one perpendicular to the mounting base. Avoid mounting with maximum vibration along the axis.Pressure FittingTwo (2) 3/16˝ O.D. pressure fittings are supplied for pressure connection with 1/4˝ push-on tubing. Both the positive (high) pressure port and the reference (low) pressure port are located on the top face of the unit, labeled High and Low respectively. For best results (shortest response times), 3/16˝ I.D. tubing is suggested for tubing lengths up to 100 feet long, 1/4˝ I.D. for tubing lengths up to 300 feet, and 3/8˝ I.D. for tubing lengths up to 900 feet.®ELECTRICAL CONNECTIONSThe Series 668 Differential Pressure Transmitter is a loop-powered 4-20 mA current output unit. The current flows into +EXC. terminal and returns back to the power supply through the -EXC. terminal. the power supply must be a DC voltage source with a voltage range between 12 and 30 VDC measured between terminal +EXC. and -EXC.The unit is calibrated at the factory using a 250 Ω load at 28 VDC.Notes:Minimum Supply Voltage (VDC) = 12 + 0.02 x (resistance of receiver plus line).Maximum Supply Voltage (VDC) = 30 + 0.004 x (resistance of receiver plus line). CALIBRATIONThe 668 series is factory calibrated and should require no field adjustment. However, both zero and span adjustments are provided. Whenever possible, any zero and/or span offsets should be corrected by software adjustment in the user’s control system. Use the zero and span adjustments on the 668 Series only if absolutely necessary. The 668 series is calibrated in the vertical position at the factory. For use in other orientations, position the unit and follow the zero adjustment procedure listed below. Pressure ranges are fixed and cannot be changed in the field.Zero AdjustmentWhile monitoring the current output with both pressure ports open to atmosphere, the zero may be adjusted. For unidirectional pressure ranges, turn the zero adjustment screw until a reading of 4 mA (±0.15 mA) is achieved.Span Adjustment (Complete the zero adjustment before setting span)Span on full scale output adjustments should only be performed by using an accurate pressure standard (electronic manometer, digital pressure gage, etc.) with at least comparable accuracy to the 668 series (<±1% full scale). With full scale pressure applied to the high pressure port (reference port open to atmosphere) adjust span to achieve 20 mA output.Example 1: Unidirectional pressure range of 0 to 1 in w.c. Apply 1.00 in w.c., adjust span to 20 mA.Notes: The input is reverse-voltage protected. The output is internally protected against damage is shorted to ground. Recheck all connections before applying power. MAINTENANCEAfter final installation of the Series 668 Differential Pressure Transmitter, no routine maintenance is required. A periodic check of system calibration is recommended. These devices are not field repairable and should be returned if recalibration or other service is required. Contact customer service to obtain an RGA number.

INSTALLATIONThe variable range differential pressure transmitter Series500is designed for horizontal,vertical or upside-down installation.The transmitters series 550 H, 550 L e 550 HH (Fig.1.1) are supplied with a clamp for installation on a 2" pipe. The transmitters series 550 FH e 550 FHH (Fig.1.2) are provided with a DN80 flange for direct mounting. Note.When mounting the unit make sure to leave sufficient free space aside the transmitter for zero adjustment and cover removal.2. COMPRESSED AIR SUPPLY(see Fig. 2.1)The pneumatic connections(1/4"NPT)areidentified by"IN"(air supply input20psi)and"OUT"(control signal output3÷15psi).Thepneumatic instrumentation operation dependson the purity of the air supply.A filter,generallyan integrated filter,must be installed in the air pressure relief system upstream to the transmitter.To prevent rusting,use only pneumatic connections in non-ferrous material (copper,nylon or polyethilene).The horizontal supply line should run towards the instrument with a minimal2%slope.The connection of the supply line to the compressed air manifold must be made in the upper part of the tubing to keep condensate from entering the instrument. If necessary,a moisture trap can be installed upstream to the filter to remove any water or oil in the air supply.For a correct operation of the pressure reducer filter,the minimal air pressure must be set at min. 2.8-3bar.We advise against the indiscriminate use of a single reducer supplying many instruments,since abrupt variations in air consumption,due to the simultaneous operation of several instruments, might adversely affect the operation of each transmitter.Fig.1.1Fig. 2.1 COMPRESSED AIR SUPLLYFig.1.23. FLOW MEASURE CONNECTIONSIn the transmitters series 550H,550L and 550HH the process connections are screwed 1/2"NPT and are identified by "+"and "-".For better maintenance operation integrated Manifolds must be installed (see Fig.2.1).Connect the pressure tap upstream to the measure flange to the transmitter input (+)and the pressure tap downstream to the measure flange to the transmitter input (-).Accuracy in the flow measurement is obtained by connecting the transmitter as in fig. 2.3, 2.4and 2.5according to the working fluid (vapour, liquid, air/gas).The diameter of the horizontal supply line should be min.20times the diameter upstream to the measure flange (d) and 10 times the diameter downstream to the measure flange (D). See Fig. 2.1FLOWFig. 2.1Fig. 2.3VAPOUR CONNECTIONSFig. 2.4LIQUID CONNECTIONSFig. 2.5AIR - GAS CONNECTIONSto the Transmitterto the Transmitter to the Transmitter4. VESSELS LEVEL MEASURE CONNECTIONSIn the transmitters series550H,550L and550HH the process connections are screwed1/2"NPT and are identified by "+" and "-".In the transmitters550FH and550FHH one of the process connections is flanged DN80(+)and the other is screwed 1/2"NPT (-). See Fig.4.4.1 ATMOSPHERIC PRESSURE VESSELS CONNECTIONFor atmospheric pressure vessel,connect the zero level tap of the vessel to the transmitter connection(+). Make sure that the connection(-)is free.See fig.4.The transmitter pressure tap must be below the zero level of the vessel.Note. If "Z" is minor than "Y" the transmitter must be provided with a depression device.Fig.4.2 DEPRESSIONDEVICE4.2 DEPRESSION DEVICE CALIBRATION1) Set the vessel to zero level3) Use the depression screw (Fig.4.2) to obtain a 3psi transmitter outputFig.4.4 ELEVATIONDEVICE4.4 ELEVATOR CALIBRATION1) Set the vessel to zero level 2) Fill it with liquid (W)3) Use the elevation screw (Fig.4.4) to obtain a 3 psi transmitter output4.3 PRESSURE VESSELS CONNECTIONFor pressure vessels,connect the transmitter as in fig.4.3.It must be provided with an elevation device (fig.4.4) since the transmitter output signal would be different from 3 psi at zero level.Note.Y=(Z multiplied by the specific weight of the measure liquid )divided by (the specific weight of the compensation liquid)5. CALIBRATION (Fig.5)Calibration of the transmitter is necessary in case a change of range is required,or if the unit has been removed for cleaning or part replacement.THE FOLLOWING CALIBRATION PROCEDURE IS TO BE PERFORMED BY AUTHORIZED PERSONNEL ONLY.For accurate calibration proceed as follows:1) Apply a 20 psi air supply.2)Connect the transmitter output to a manometer with scale amplitude sufficient for calibration to be carried out3)Connect the transmitter pressure tap(+)to a manual pressure regulator controlled by a manometer with scale amplitude sufficient for calibration to be carried out.4) Keep the pressure tap (-) free to atmospheric pressure5)Loosen the nut(36),place the range setting ring(19)as indicated by the scale alongside the range rod and tighten nut (36).6) With instrument at zero differential pressure, adjust screw (23) until the output reads 3 psi.Note.In case the diaphragm has been removed,proceed as follows:remove bottom plug(34),insert into the opening a1/4"Allen wrench and loosen locknut.Adjust zero screw and tighten nut.Pay attention not to move the force bar from its normal position.In case of output pressure change,loosen again locknut,retighten and mount the plug(1).If output pressure still differs more than0.4psi,it indicates that diaphragm is not perfectly aligned with the body. Provide therefore for alignment.7)Apply to pressure tap(+)a pressure equal to required range.If output value is less than15psi,move ring (19) upwards, or vice versa.8) Repeat steps 6 and 7 until desired accuracy is obtained.2729351514162036193022232425181732111101213642821 269313233 Fig.5696. MAINTENANCEIn normal operating conditions the transmitter Series500does not require specific maintenance.The pneumatic instrumentation operation depends on the purity of the air supplied.Daily bleed the filter in the air supply line until any water, air or other impurities are completely expelled.6.1 DYNAMIC RESTRICTION CLEANING (Fig.5)Dust and dirt in the air supply might adversely affect the correct operation of the transmitter.For cleaning, proceed as follows:1) Eliminate supply to transmitter.2) Remove screw (64) and clean by means of a Ø 0.15 mm steel wire, as shown in Fig. 6.1.3) If the capillary orifice is obstructed, clean it with a bath in trichloroethylene and a blow of compressed air. Before fastening screw (64), we recommend lubricating O-Rings by applying a coat of silicone lubricant.Fig.6.1 Dynamic Restriction Cleaning6.2 NOZZLE CLEANING (Fig.5)1) Eliminate supply to transmitter2) Engage nut (29) and remove nut (26).3) Remove the pipe connected to relay (69).4) Clean the nozzle by means of a Ø 0.6 mm steel wire, as shown in Fig.6.2.5) If the nozzle is obstructed, clean it with a bath in trichloroethylene and a blow of compressed air.Fig.6.2 Nozzle cleaning7. DISASSEMBLINGNormal transmitter operation does not require removal of parts other than those described in the previous paragraph.NOTE.THE FOLLOWING DIAPHRAGM REPLACEMENT PROCEDURE IS FOR EMERGENCY ONLY AND IS TO BE PERFORMED BY AUTHORIZED PERSONNEL ONLY.7.1 DIAPHRAGM REPLACEMENT (Fig. 7.1)1) Cut off transmitter from process.2) Open vent screw (31) and drain nut (32) on both sides.3) Remove the 4 nuts (2). Do not pull bolts (33) out of the body.4)Remove the bottom plug(1).Insert a1/4"Allen wrench into the opening and loosen the locking nut without completely uncrewing it.5) Remove the diaphragm (6) and the Teflon rings (5).6) Replace diaphragm and perform the calibration procedure indicated in paragraph 5.Fig.7.1 Diaphragm Replacement。

Offset Calibration偏移误差校正 This function can be used to correct the zero-point deviation (offset) of the output signal in depressurized state (example: to 0 V/4mA at zero Pa). Disconnect the unit from the pressure by opening both hose nozzles or removing the hoses. Then press the "M" button for 5 s. Setting of Switching Output This function is used to set the switching output to "switched through" for a pressure you have defined. Apply the pressure or pressure differential at which the switching output is to be connected. Then press the "S" button for 5 s until the LED flashes quickly (= value is saved). The LED lights up as soon as the defined pressure is reached or exceeded.
