Silicon Pressure Sensors
The MPXM2053 device 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.
Features
• Temperature Compensated Over 0°Cto +85°C
• Available in Easy--to--Use Tape & Reel
• Ratiometric to Supply Voltage
• Gauge Ported & Non Ported Options
Application Examples
• Pump/Motor Controllers
• Robotics
• Level Indicators
• Medical Diagnostics
• Pressure Switching
• Non--Invasive Blood Pressure Measurement

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 side (P1) relative to the vacuum side (P2). Similarly,
output voltage increases as increasing vacuum is applied to the vacuum side (P2)
relative to the pressure side (P1).
Preferred devices are Freescale Semiconductor recommended choices for future use and best overall value.
