Introduction

Assembled MPM280 Piezoresistive Pressure Sensor

Put general MPM280 pressure sensor into the housing with standard or specialized thread; use face type seal or waterline seal; with flexible construction and strict inspecting and screening; the assembled MPM280 pressure sensor has similar application with general type pressure sensor, it can be used for mounting and production of different pressure instruments;


Welded MPM280 Piezoresistive Pressure Sensor

Put general MPM280 pressure sensor into the housing with standard or specialized thread; and weld sensor with housing together, no O-ring for sealing. The whole product has flexible construction, it has wider application fields than general pressure sensor, and can be used for mounting and production of different pressure instruments;

Notes

1.We suggest you to use Floating construction when you install the sensor to prevent affecting sensor stability;

2.Please pay attention to protect sensor isolated diaphragm and ceramic compensated board, to avoid damaging sensor or affecting the performance;

3.Temperature resistant range of standard Viton O-ring of sensor is -20℃ ~ 250℃. When working temperature is lower than -20℃, or sensor is applied in critical environment, please contact us.
