Product Overview
The MPR Series is a compact, piezoresistive silicon pressure sensor featuring a digital output for precise pressure readings across a specified full-scale pressure span and temperature range. It is calibrated and compensated for offset, sensitivity, temperature effects, and non-linearity via an on-board ASIC, ensuring high accuracy and ease of use. Its very small form factor and digital I2C or SPI-compatible output make it ideal for higher volume medical devices, commercial appliances, and industrial/HVAC applications, offering plug-and-play implementation and enhanced system-level connectivity. The sensor boasts ultra-low power consumption and is compatible with a variety of liquid media, with absolute and gage pressure types available.
