Piezoresistive Pressure Sensor


Description of piezoresistive pressure sensor

Based on advanced piezoresistive silicon technology, UPX19 is manufactured by adopting piezoresistive silicon chips. The sensor has a diameter of 19mm and is fully welded with 316L stainless steel structure. The precisely adjusted thick-film circuit carries on wide temperature range compensation and zero offset compensation to the sensing element. The measured pressure is transmitted to the piezoresistive silicon sensing element through 316L isolated diaphragm and the filled oil, thus to realize the precise transformation of electrical signal from pressure.

UPX19 OEM pressure sensor is the core part (OEM) of making pressure transducer & transmitter.This product is designed for easy installation with O-rings as sealing method. As one kind of high performance pressure-sensitive device, UPX19 pressure sensor can be amplified and processed to assemble pressure transmitter with standard signal output very conveniently.

UPX19 is widely used in process control in petroleum, chemical industry, metallurgy, electric power, aviation, astronautics, medical equipment, automobile etc.
