MPM281 High Stable Pressure Sensor Introduction
MPM281 high stable OEM sensor is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable silicon die, stainless steel 316L housing with diameter 19mm. 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. It can be filled with Fluorinated Oil. Because of its good biological inertness, it can dissolve a large amount of breathing gas, and can be quickly discharged from the human body. It is more suitable for the pressure measurement of the oxygen in medical applications.
MPM281 pressure sensor is inspected and screened on automatic production line, testing and checking time after time strictly. It is widely used for various pressure measurement fields.
