Product Overview
The MPR Series is a compact, piezoresistive silicon pressure sensor offering a digital output for precise pressure measurement across a wide range of applications. Featuring calibration and compensation for offset, sensitivity, temperature effects, and non-linearity via an onboard ASIC, this sensor is ideal for higher volume medical, commercial appliance, and industrial/HVAC devices. Its very small form factor, digital I2C or SPI-compatible output, and IoT readiness simplify integration and enhance system connectivity. The MPR Series provides a Total Error Band specification for comprehensive performance measurement, reducing manufacturing costs and enabling sensor interchangeability.
