The MPVZ2202 device series is a silicon piezoresistive pressure sensor providing a highly accurate and linear voltage output - directly proportional to the applied pressure. The sensor is a single monolithic silicon diaphragm with the strain gauge and a thin-film resistor network integrated on-chip. The chip is laser trimmed for precise span and offset calibration and temperature compensation. They are designed for use in applications such as pump/motor controllers, robotics, level indicators, medical diagnostics, pressure switching and respiratory equipment.

Sensing Element Thin Film Temperature Compensation And Calibration Circuitry 2 Vout+ 4 Vout- 1 GND Figure Temperature Compensated Pressure Sensor Schematic VOLTAGE OUTPUT VERSUS APPLIED DIFFERENTIAL PRESSURE The differential voltage output of the sensor is directly proportional to the differential pressure applied. The output voltage of the differential or gauge sensor increases with increasing pressure applied to the pressure P1 side relative to the vacuum P2 side. Similarly, output voltage increases as increasing vacuum is applied to the vacuum P2 side relative to the pressure P1 side. Table Maximum Ratings 1 Rating Value |
