It uses high stable silicon die. Stainless steel 316L housing with diameter 019mm. 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. MPM289 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.

It is recommended that the sensor should be installed as Suspended Mode to avoid face tight press 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°C ~ 2500. When working temperature is lower than -20C, or sensor is applied in critical environment, please contact us. MICRO SENSOR CO.,LTD...
