Diffused silicon pressure transmitter
Purpose The DWP-800 transmitter is composed of a piezoresistive sensor and a signal conversion module. The core component of the sensor is a monocrystalline silicon wafer. When the monocrystalline silicon wafer is under pressure, its own resistivity will change. Four resistors are diffused on the silicon chip through the semiconductor planar process and connected to form a Wheatstone bridge. Under the action of a constant current, the voltage signal proportional to the pressure signal can be ...
