Product Overview
The MPR Series is a compact, piezoresistive silicon pressure sensor designed for high-volume medical, commercial appliance, and industrial/HVAC applications. It offers a calibrated and compensated digital output via I2C or SPI, simplifying implementation and system connectivity. With a very small form factor, wide pressure ranges, and enhanced performance through direct microprocessor interfacing, the MPR Series provides a cost-effective, high-accuracy solution for portability and space-constrained designs. Its Total Error Band specification minimizes testing and calibration needs, ensuring sensor interchangeability and improved manufacturing efficiency.
