Liquid Pressure Sensor

Description of liquid pressure sensor

UPX13 OEM piezoresistive liquid pressure sensor is a pressure measurement device based on corrugated stainless steel isolated diaphragm. This pressure sensor is featured with integrated structure, high measuring pressure, good stability and high reliability, and is particularly suitable for high pressure measurements. By using high precise and high stable pressure-sensitive chips, the pressure sensitive elements are assembled in the imported production lines, and tested by computer automatically after zero correction and temperature compensation. UPX13 liquid pressure sensor has good interchangeability because of its general assembly sizes.

UPX13 liquid pressure sensor has been widely used in petrochemical, process control, hydraulic systems, pressure instrumentation, pressure calibration equipment, refrigeration equipment and air conditioning systems and other industries.
