BS-30D Intelligent Pressure Transmitter Circuit Board

BS-30D Intelligent Pressure Transmitter Circuit Board

Features

◆Two-wire 4-20mA working mode, 5 -digit LCD display.

◆ Sensor constant current and constant voltage excitation, constant current 0.05mA—0.75mA adjustable, constant voltage 4V and 2.5VDC optional.

◆The ADC differential input amplitude is ±5mv~±4000mv , providing a 24 -bit core resolution, and the maximum effective bit reaches 23 bits. The built-in magnification of the circuit board is 1~255 times. Support automatic polarity conversion of sensor signal.

◆ Suitable for pressure sensors such as diffused silicon pressure, ceramics, strain, etc.

◆ Provide range shift function, 19 kinds of unit conversion, display resolution adjustment, suitable for the special needs of various customers.

◆ 2~3 points of non-linear correction function to eliminate the non-linear error of the sensor.

◆ Fully digital calibration, without any movable potentiometer, lower temperature drift.

◆ Strengthen anti-interference design, suitable for all kinds of industrial environments with harsh electromagnetic environment.
