Flush Diaphragm 60MPa 100MPa Gas Pressure Sensor Core MEMS Technology
Flush Diaphragm 60MPa 100MPa Gas Pressure Sensor Core MEMS Technology
Description
Gas Pressure Sensor Core is a standard and common sensor applied in air and chemi-industry, liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. Silicon Oil-filled and isolated from measured media by a stainless steel diaphragm and body. The most important specification for industry
application is long term stability.
The PS19B sensoris designed for industry application with perfect long term stability. It have good ability on preventing fouling, crystallization and jamming of thick liquids .PS19B is widely used in food, medicine, health and wine industry etc
Feature
● MEMS technology
● Imported Piezoresistive silicon chip employed
● Sensor diameter:19mm
● Used in food, medicine, health and wine industry etc
