Gas, liquid pressure measurement Liquid pressure system and switch Aviation and navigation inspection Features • Pressure range: 0kPa ~ 100kPa... 100MPa • Gauge, absolute and sealed gauge • Constant current / Constant Voltage power supply • Isolated construction, enable to test measure various fluid media • 012.6mm compact size OEM pressure sensor • Stainless steel 316L/ Hastelloy C materials • Wide temperature compensation range -10°C ~ 80°C Application • Industrial process control • Level measurement • Pressure inspection meter • Pressure calibrator • Cooling equipment and air conditioner Introduction MPM283 piezoresistive pressure sensor is OEM pressure sensor with stainless steel isolated diaphragm, the whole product has integrated construction, high endurance, high stability and good reliability , it can be used specially for middle and high pressure measurement. The sensor using high accurate and stable pressure die, are produced on the advanced production line. Sensors are tested automatically, and compensated zero and temperature performance with provided resistors. The installation dimension is consistent with general products which makes the sensor has a good interchangeability. Electric Performance Power supply: <2.0mADC;^ 10V DC Electric connection: Kovar pin or 100mm silicon rubber flexible wires Common mode voltage output: 50% of input (typ.) Input impedance: 3kQ~ 8kQ Output impedance: 3.5kQ ~ 6kQ Response (10%~90%): <1ms Insulated resistor: 100MQ, 100VDC Overpressure: 1.5 time FS or 110MPa(min. value is valid) Construction Performance Diaphragm: stainless steel 316L Housing: stainless steel 316L Pin: Kovar or silicon rubber flexible wires O-ring: Viton Net weight: ~ 8g MICRO SENSOR CO.,LTD

Open the catalog to page 2The other pins are useless Note: The actual electric connection method, please check the parameter label enclosed with products. 1. The resistance bridge on the left of the dashed is sensing die’s bridge circuit; 2. If the sensor has no compensated board, it is needed to connect outer compensated resistor to compensate zero and temperature drift, the connection to see the above chart. Connect zero calibrated resistor R3 (R4), the other resistor R4 (R3) is short circuit as negative power supply; R1 or R2 is zero temperature compensated resistor, only one of them is used, the other is open...
