Description

0~30bar Low Range Accurate 4~20mADC 1~5VDC Water Liquids Oil Differential Pressure Transmitter

Description
MDM490 uses piezoresistive sensor as the sensing element, silicon oil is filled between the die and two diaphragms. When the measured differential pressure is added on the two diaphragms, the pressure could be transferred onto the die through silicon oil. The sensor die connects with an amplifier circuit through wires, uses the semiconductor's piezoresistive effect to transform the differential pressure signal into the electric signal. Since the signal output of the Wheatstone bridge on the die has a good linear relationship with the differential pressure, the differential pressure can be accurately measured.
