MPM180/MPM185 TO-8 Housing Piezoresistive Pressure Sensor Features • Pressure range 0kPa ~ 7kPa.. .1MPa • Gauge, absolute and differential pressure • Constant current / Constant Voltage power supply • Measure non-conductive, non-corrosive gas or liquid • TO-8 packing, enable for PCB installation • Standard 3/16 inch port • Low cost, compact size Application • Air pressure control • Physiology guarding • Medical equipment, blood-pressure meter • -Pressure calibrator • Aviation and spaceflight • Communication system Introduction MPM180/MPM185 TO-8 housing piezoresistive pressure sensor uses advanced ion implantation and micro-mechanical processing technology to produce silicon die which has Wheatstone Bridges and precise mechanical structure, packing sensor as TO-8 type. The measured pressure is transmitted onto the silicon die through pressure port directly. And the pressure value can be transformed into output voltage signal by linearity relationship. Laser trimming compensates sensor temperature performance. The sensor could be used on PCB or small space fields to measure gauge, absolute or differential pressure for the gas or liquid.
