The industrial pressure transmitter converts the physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals (such as 4~20mADC, etc.) to supply secondary instruments such as indicato
Pressure transmitter is a common sensor in industrial. Imported high-precision and high stability pressure sensitive chips are selected for diffused silicon pressure transmitters. Sensitive chips are fabricated by an advanced micro-mechanical etching process, which forms a Wheatstone bridge by diffusing four high-precision resistors with temperature compensation on silicon wafers.
Because of the piezoresistive effect, there are some changes in the resistance values of the four bridge arm resistance, so as to make the bridge unbalanced, and then the sensor outputs an electric signal corresponding to the change of pressure. The output electric signal is compensated by amplification and non-linear correction circuit, which generates voltage and current signals which correspond linearly to the input pressure.
