Overview

The MPM3801GRF is a digital IIC pressure transmitter tailored for volume corrector and precision industrial applications. Built around a robust stainless steel oil‑filled transducer, the device delivers high stability and corrosion resistance in demanding environments. It supports digital communication through standard I²C or SPI protocols, enabling seamless integration with microcontrollers and data acquisition systems. Its low power design makes it suitable for battery‑powered or low‑consumption systems. Secondary temperature compensation enhances measurement accuracy up to ±0.25% of full scale, while compliance with RoHS and REACH ensures environmental safety standards are met. Typical applications include gas pressure monitoring, integration with gas flowmeters, roots and turbine flow measurement systems, and other intelligent pressure instruments across process industries.
