BS-5 2088 Intelligent Pressure Transmitter Circuit Board

1. Overview:

Fully intelligent two-wire 4-20mA working mode, 4-digit 0.36 " digital tube display.

The  sensor is excited by constant current and constant voltage , constant current 0.4mA, constant voltage 2.5VDC.

ADC input amplitude is ±5mv~±80mv, providing 24-bit core resolution, and the useful number of bits is up to 18 bits. The built-in magnification of the circuit board is 12~200 times. Support automatic polarity conversion of sensor signal.

Suitable  for diffused silicon pressure sensor and ceramic pressure sensor.

Provide  zero reset migration function, batch parameter modification function, panel button modification function, suitable for the special needs of various customers.

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

Strengthened  anti-interference design, suitable for all kinds of industrial environments with harsh electromagnetic environments.uUnique  nonlinear correction function, ideal to eliminate the nonlinear error of the sensor.

Support passive migration and range scaling . Suitable for signal processing of various sensor types.
