Based advanced ion implantation and micro-mechanical processing technology, UPX18 water pressure sensor is manufactured based on silicon chip which has Wheatstone Bridges and precise mechanical structure.

The measured pressure acts on silicon chip through pressure port directly, and the pressure value is transformed to output voltage signal in linearity relationship.

This water pressure sensor is suitable for installation in small space, and compatible for non-conductive & non-corrosive liquid or dry gas gauge pressure, absolute pressure or differential pressure measurement.

UPX18 water pressure sensor has been widely used for air pressure control, physiology guarding, medicine equipment, blood-pressure meter etc.
