    According to different applications, working environment as well as measured media, customers may need to choose different pressure sensors.

    MPM280 pressure sensor is piezoresistive, silicon oil filled with stainless steel construction. It is widely used for measuring pressure which is compatible with stainless steel and Viton.

    ·Pressure Range: 0kPa~20kPa…100MPa

    ·Repeatability: ±0.05%FS (Typ.), ±0.075%FS (Max.)

    ·Pressure type: Gauge, absolute and sealed gauge

    Different from MPM280, MPM281 pressure sensor uses high stable silicon die which ensures high level stability and wider -10~80 ℃ compensated temp. Moreover, it is able to measure low range pressure.

    ·Pressure range 0kPa~7kPa…100MPa

    ·Repeatability: ±0.05%FS (Typ.), ±0.075%FS (Max.)

    ·Pressure type: Gauge, absolute and sealed gauge

    Both MPM280 and MPM281 pressure sensor are 19mm diameter while MPM283 pressure sensor has smaller dimension, 12.6mm diameter and 16.8mm available, proper for those applications which has requirement for compact outline.

    ·Pressure Range: 0kPa~20kPa…100MPa

    ·Repeatability: ±0.05%FS (Typ.), ±0.075%FS (Max.)

    ·Pressure type: Gauge, absolute and sealed gauge

    ·Nonlinearity: ±0.15%FS (Typ.), ±0.25%FS (Max.)

    ·Hysteresis: ±0.05%FS (Typ.), ±0.075%FS (Max.)

    Besides the general pressure sensors mentioned above, we are capable of customized products and solutions. You can tailor your pressure sensor such as pressure port, outline dimension etc. Feel free to contact us via sales@microsensor.cn and our professional R&D and sales team are ready to offer you satisfied service.

    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 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. It is widely used for various pressure measurement fields.
