霍尔电流传感器的应用注意事项

霍尔电流传感器的应用注意事项如常规电流传感器一样，一般霍尔电流传感器都有正极(+)、负极(-)、测量端(M)及地(0)四个管脚，但带线电流传感器则没有此四个管脚，而是有红、黑、黄、绿三根引线，分别对应于正极、负极、测量端及地。

同时在大多传感器中有一内孔，测量原边电流时要将导线穿过该内孔。

孔径大小与产品型号、测量电流大小有着必定的关系。

不管是什么型号的电流传感器，安装时管脚的接线应依据说明书所注状况进行相应连线。

1) 在测量沟通电时，必需强制使用双极性供电电源。

即传感器的正极(+)接供电电源“+VA”端，负极接电源的“-VA”端，这种接法叫双极性供电电源。

同时测量端(M)通过电阻接电源“0V”端(单指零磁通式)。

2) 在测量直流电流时，可使用单极性或单相供电电源，即将正极或负极与“0V”端短接，从而形成只有一个电极相接的状况。

另外，安装时必需全面考虑产品的用途、型号、量程范围、安装环境等。

比如传感器应尽量安装在利于散热的场合。

除了安装接线、即时标定校准、留意传感器的工作环境外，还应留意一下事项以保证测试精度：1) 原边导线应放置于传感器内孔中心，尽可能不要放偏;2) 原边导线尽可能完全放满传感器内孔，不要留有空隙;3) 需要测量的电流应接近于传感器的标准额定值IPN，不要相差太大。

如条件所限，手头仅有一个额定值很高的传感器，而欲测量的电流值又低于额定值许多，为了提高测量精度，可以把原边导线多绕几圈，使之接近额定值。

例如当用额定值100A的传感器去测量10A 的电流时，为提高精度可将原边导线在传感器的内孔中心绕十圈(一般状况，NP=1;在内孔中绕一圈，NP=2;……;绕九圈，NP=10，则NP×10A=100A与传感器的额定值相等，从而可提高精度)。

Thermal CharacteristicsTable 1.7. Absolute Maximum Ratings1Functional Description 2. Functional DescriptionThe Si7211/2/3/4/5/7 family of Hall Effect magnetic sensors digitize the component of the magnetic field in the z axis of the device (pos-itive field is defined as pointing into the device from the bottom). The digitized field is then converted to an output format of analog, PWM or SENT and presented on the output pin.Table 2.1. Part DescriptionRefer to the Magnetic Sensors Selector Guide for the two digit number after the die revision which gives more details about output, sampling frequency and other details.Data output is always unsigned. That is, half scale (V DD/2 for analog out parts, 50% duty cycle for PWM output parts and 2048 (0x800) for SENT output parts) corresponds to zero field.The parts are preconfigured for the magnetic field measurement range, idle time, temperature compensation and digital filtering and will wake into this mode when first powered. The specific configuration output type (open collector or push pull) are determined by the part number.Analog Output 3. Analog OutputFor the Si7211, the analog output is V DD/2 at zero field and goes from nearly zero at large negative field to nearly V DD at large positive field.B(mT)=(20.47or204.7)×(2×Vout Vdd−1)4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.For high voltage parts (Si7216), the output is ratiometric to an internally derived V DD of 5V (± 5%) so long as the input V DD is > 6 V.B(mT)=(20.47or204.7)×(2×Vout5−1)For V DD < 6 V the internally derived reference drops 1 V for each 1 V drop in V DD to the minimum recommended working voltage of 4.0 V.PWM Output Description 4. PWM Output DescriptionThe PWM output can be configured as open drain or push pull. High voltage parts can only be configured as open drain. The PWM duty cycle is factory configured and is normally set to in the range of 10 Hz to 1 KHz and is ±5%. See ordering guide for specific part num-bers..As each measurement completes, the next PWM cycle will be updated to reflect the last measurement result. The duty cycle varies from 0 to 100% where 50% duty cycle means zero field, 0 % duty cycle generally means maximum negative field (-20.47 mT or -204.7 mT) and 100% duty cycle generally means maximum positive field (+20.47 or +204.7 mT). The high portion of the PWM is output first so thatB(mT)=(20.47or204.7)×(2×Thigh−1)Thigh+TlowThe host processor should look for a variation in the magnetic field to determine the entire system is working properly.4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.5. SENT OutputThe Si7213 and Si7215 output data in SENT (Single Edge Nibble transmission) format conforming to J2716 January 2010. All SENT output parts are configured as open collector.SENT protocol messages consist of:• A calibration/synchronization period consisting of 56 clock ticks• A status and serial communication 4-bit nibble• A sequence of up to six data nibbles• A one nibble checksum•Each nibble is 12 to 27 clock ticks•An optional delay pause pulseFigure 5.1. SENT Timing DiagramAs can be seen, each part of the sequence is determined by the timing between falling edges of the open drain sent output. First, a time of 56 clock ticks is produced so that the receiver can calibrate itself to the Si7213/5 speed. Then a total of 8 nibbles (4 bits per nibble) is produced. The edge to edge time of each nibble is 12 clock ticks for a data nibble of 0000b 13 ticks for a data value of 0001b and so on up to 27 ticks for a data value of 1111b.The nominal tick time has been standardized at 5 μsec (±5%) however this is configurable.5.1 tSENT Status NibbleIn the Si721x the four bit status nibble is defined as follows:•Bit 3 and Bit 2 always transmitted as zeroes (No serial message support)•Bit 1 and Bit 0•00 Normal; No error condition•01 Error condition•10 Positive field BIST active•11 Negative field BIST active5.2 SENT Data NibblesThe Si7213 and Si7215 are configurable to support a variety of options. The standard option follows J2716 A.3 where:For magnetic field, 3 nibbles are put together for a total 12 bit data word with values that can range from 0 to 4095. For magnetic field data, 2048 corresponds to zero field. The Si7213 can be configured for ± 20.47 mT full scale or ± 204.7 mT full scale. On the 20.47 mT full scale 1 LSB is 0.01 mT and on the 204.7 mT full scale 1 LSB is 0.1 mT.5.3 CRC CalculationThe CRC is calculated based on the 6 data nibble according to x4 +x3 + x2 + 1 with a seed value of 0101 as per the recommendations in J7216 section 5.4.2.2. The legacy CRC calculation is not supported.5.4 SENT Pause PulseThe Si7213 and Si7215 are configurable for a pause pulse that is 12 ticks low, 256 ticks wide. However, the standard offering is no pause pulse.5.5 SENT Frame RateFor the standard offering with no pause pulse, each message will be 154 to 270 ticks in length. At a tick time of 5 μsec this is 770 to 1350 μsec. This gives an average frame rate of approximately 1 msec for the standard tick time of 5 μsec. Conversion start is synchronized to the start of the synch pulse and is normally completed before the synch pulse completes so the data that is reported is the data obtained during the synch pulse time.5.6 BIST Activation During SENT OperationFor 3-pin packages BIST can be activated by holding the output pin low for the entire message.Once BIST is activated SENT messages resume 12 ticks after the SENT IO pin is detected high. Eight positive field BIST messages are followed by eight negative field BIST messages followed by a return to normal messages.The nominal magnetic field output of the on-chip generator varies with coil current. The coil current varies with the coil resistance and power supply voltage, so the nominal magnetic field output varies according to:Bout = BperVnom x VDDBperVnom is 1.6 mT/VThis can be used to calculate the expected magnetic field from the test coil for a given V DD. This is somewhat temperature dependent, so the actual measured field will vary according to the accuracy of the part as well as temperature. Generally, as the coil is turned on and off the measured variation in field should be within ±25% of expectation based on the calculated field generation.The host processor should look for a variation in the magnetic field output to determine the entire system is working properly.The 4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.6.

An AC voltage is applied to these electrodes which generates a current in the medium.The electric resistance or its reciprocal value, the conductance G, is calculated according to Ohm’s law. The specific conductivity κ is determined using the cell constant k that is dependent on the sensor geometry.Condumax CLS21 / CLS21DDependability with CLS21D ReliabilityThe Memosens technology digitalizes the measured values in the sensor and transfers them to the transmittercontactlessly and free from interference potential. The result:•An automatic error message is generated if the sensor fails or the connection between sensor and transmitteris interrupted.•The availability of the measuring point is dramatically increased by immediate error detection.MaintainabilitySensors with Memosens technology have integrated electronics that allow for saving calibration data andfurther information such as total hours of operation and operating hours under extreme measuring conditions.When the sensor is connected, the calibration data are automatically transferred to the transmitter and used tocalculate the current measured value. Storing the calibration data in the sensor allows for calibration andadjustment away from the measuring point. The result:•Sensors can be calibrated unter optimum external conditions in the measuring lab. Wind and weather doneither affect the calibration quality nor the operator.•The measuring point availability is dramatically increased by the quick and easy replacement of precalibratedsensors.•Maintenance intervals can be defined based on all stored sensor load and calibration data and predictivemaintenance is possible.•The sensor history can be documented on external data carriers and evaluation programs at any time. Thus,the current application of the sensors can be made to depend on their previous history.IntegrityThe inductive and non-contacting measured value transmission of Memosens guarantees maximum processsafety and offers the following benefits:•All problems caused by moisture are eliminated.–The plug-in connection is free from corrosion.–Measured value distortion from moisture is not possible.–The plug-in system can even be connected under water.•The transmitter is galvanically decoupled from the medium.•EMC safety is guaranteed by screening measures for the digital measured value transmission.
