Description

MDM490 piezoresistive differential transmitter uses a solid piezorsistive pressure sensor as the sensing element. The product is silicon oil filled, compact and highly accurate.
We design this transmitter with piezoresistive effect by applying semi-conductive silicon, to make the differential pressure transform to electrical signals. Since the Wheatstone bridge output signal of the sensing element has a good linear relation with differential pressure, it is easy to measure the pressure accurately.
