Flush Membrane Pressure Sensor
Description
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 of this flush membrane pressure sensor is welded in the front of the sensor body, which has G1/2 or others.
Features
◇Good performance, entire solid state, high reliability;
◇Operating temperature range: -40~+125℃;
◇Have gauge pressure, absolute pressure and sealed gauge pressure;
◇Flush membrane pressure sensor has imported pressure silicon dies;
◇Flush diaphragm structure, suitable for medical, food, beverage industry.
