Environment Condition Shock: no change at 10gRMS, (20-2000) Hz Impact: 100g, 11ms Media compatibility: the liquid or gas which is compatible with stainless steel and Viton Basic Condition Media temperature: (35±1)°C Environment temperature: (35±1)C Shock: 0.1g (1m/s2) Max Humidity: (50%±10%)RH Local air pressure: (86 - 106)kPa Power supply: (1.5±0.0015)mA DC Outline Construction (Unit: mm) MPM283 Type II The suggested mounting dimension is 012.6*°q2 mm MICRO SENSOR CO.,LTD

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 circuit.
