Hydraulic Piezo Resistive Pressure Sensor

 

Description
YYS-19 Hydraulic Piezo Resistive Pressure Sensor is standard and common OEM  pressure sensor ,which has good sensitivity, linearity and hysteresis for industry and many other hostile environments. Silicon Oil-filled and isolated from measured media by a stainless steel diaphragm and body.It uses Laser trimming technics or outer resistors to do temperature compensation and zero correction. The whole products has high reliability,high endurance and long stability.
The sensors are widely used for chemi-industry, process control. Liquid pressure system,etc.
