1.1 Overview
DBYG pressure transmitter uses the sensor made of imported sensitive elements and has been given precision compensation by microcomputer, so it has high precision and good stability. Its A/D signal processing unit consists of integrated circuit of high quality and the output current signal can be directly connected with industrial instruments and computer control systems so that automatic detection and control during manufacturing process can be achieved. It is applicable to various industrial fields for measuring pressure of gas and liquid.
1.2
Working Principle
When the sensor is under pressure, the diaphragm on the sensitive elements will become deformed causing the output voltage changes of the Wheatstone bridge. It is the signal processing circuit in the transmitter that amplifies that kind of change into standard current signal output. The output signal is proportional to the applied pressure.
