Overview
BT-22 transmission board is the latest product with high cost performance. Adhering to the temperature transmitter circuit design experience and instrument manufacturing experience of Baoji Xingyuteng. Suitable for signal conditioning of PT100 sensors. The output signal of the circuit board is a two-wire system 4-20mA, and the input is a differential bridge signal. Multi-point curve fitting non-linear calibration function completely eliminates the non-linear error of the sensor. Large-screen LCD display ( with backlight ) , fully digital design , direct digitization of the sensor, low temperature drift , and strong anti-interference ability. Support passive migration and range scaling . Use modbus-rtu protocol to read and calibrate . It is also suitable for RS485 communication in industrial field .
