Introduction

MPM281 high stable OEM pressure sensor is the piezoresistive type with isolated construction and precise compensation. It uses high stable silicon die, Stainless steel 316L housing with diameter Ф19mm. 

Wider temperature compensation and zero correction are calibrated by laser trimming technics. The measured pressure is transmitted onto silicon die through 316L diaphragm and inner media, to transform the pressure to electric signal.


MPM281 pressure sensor is inspected and screened on automatic production line, testing and checking time after time strictly. this pressure sensor is widely used for various pressure measurement fields.

*The default code for electric connection is “1”on the parameter card. And it is also allowed to print code “1” if the electric connection is flexible wire (original code “2”). The wire length shall be as per customers’ request on the contact.


Notes

1.It is recommended that the sensor should be installed as Suspended Mode to avoid face type seal and avoid affecting sensor stability.

2.Please pay attention to protect the diaphragm and the compensated board to prevent any damage or bad performance.

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