Flush Membrane Pressure Sensor
Description of flush membrane pressure sensor
Based on piezoresistive silicon technology, UPX20S flush membrane pressure sensor is manufactured from piezoresistive silicon dies. It is features a fully welded construction with a complete flush diaphragm contact the pressure medium, able to measure pressure of viscous liquids or fluids. The measured pressure is transmitted to the piezoresistive silicon sensing element through 316L isolated diaphragm and inner medium, thus to realize the precise transformation of electrical signal from pressure.
The flush diaphragm is welded in the front of the sensor body, which has G1/2 or others.
UPX20S flush membrane pressure sensor is suitable for applications in medicine, food and beverage industry.
