Introduction
SPT83 piezoresistive pressure sensor is OEM pressure sensor with stainless steel isolated diaphragm, the whole product has integrated construction, high endurance, high stability and good reliability , it can be used specially for middle and high pressure measurement. The sensor using high accurate and stable pressure die, are produced on the advanced production line. Sensors are tested automatically, and compensated zero and temperature performance. With identical mounting dimension, the sensors are widely used for chemi-industry, process control, liquid pressure system and switch, etc.
