MPM283 Piezoresistive OEM Pressure Sensor

Specifications

Product Overview

MPM283 piezoresistive pressure sensor is OEM pressure sensor with stainless steel isolated diaphragm, the whole product has integrated construction, high endurance, and good reliability, it can be used specially for middle and high pressure measurement. The sensor uses high accurate and stable pressure die, are produced on the advanced production line. Sensors are tested automatically, and compensated zero and temperature performance. With identical mounting dimension, the sensors are widely used for chemi-industry, process control, liquid pressure system and switch, etc.

Basic Specification

 Electrical Connection

1. The resistance bridge on the left of the dashed is sensing die’s bridge circuit;
2. 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. The user could select according the specification label which is enclosed with pressure sensor; R5 is sensitivity compensated resistors. We suggest that please connect the outer compensated resistors with pressure sensor as close as possible.

Order Note
1. Please pay attention to protect the diaphragm to prevent sensor from damaging;
2. Please do not pull or drag the Kovar pin or flexible leading wires;
3. Temperature resistant range of standard Viton O-ring of sensor is -20°C ~ 250°C. When working temperature is lower than -20°C, or sensor is applied in critical environment, please contact us.
