Differential Pressure Sensor

Model: UPX30

Description

Based on piezoresistive silicon technology, UPX30 differential pressure sensor is manufactured from piezoresistive silicon dies. This differential pressure sensor has two flush diaphragms facing the pressure medium, it is able to measure differential pressure of gas or liquids. The diaphragm form a chamber, in which oil is filled to isolate the sensing element and transfer pressure. The measured differential pressure is transmitted to the piezoresistive silicon sensing element through 316L isolated diaphragm and internal medium, thus to realize the precise transformation of electrical signal from pressure. This isolation enables the sensor to measure the pressures of corrosive fluids as well as electro conductive liquids.

UPX30 differential pressure sensor is tested by computer automatically, and is compensated by compensation board for zero and sensitivity. Its profile and assembly size have good interchangeability with some overseas' general products.
