Oil Pressure Sensor
Description of oil pressure sensor
Based on metal foil strain gauge technology, the sensing elements of UPX-7 series oil pressure sensors are strain gauges, these strain gauges form a Wheatstone bridge on back of the diaphragm to sensing the deformation of the diaphragm, this deformation results from the pressure which act vertically to the diaphragm.
UPX7-a strain gauge pressure sensor is made with inner cavity, for pressure range less than 400bar, the sensor adopts
welding sealing method, for 400bar~600bar, it is designed with integrated structure.
UPX7-a oil pressure sensor is widely used in food, medicine and beverage industries.
Features of oil pressure sensor
◇High accuracy, high performance
◇Suitable for middle and high pressure measurement
◇Isolated structure, suitable for many kinds of pressure medium
◇Anti-corrosive, anti-attrition, anti-impact
◇Pressure port has cavity type and flush diaphragm
