Overview

HPM81/82 single crystal silicon differential pressure transmitter adopts MEMS technology, with high stability and accuracy up to 0.075%. The transmitter is equipped with a complex signal processing module with integrated static pressure and temperature compensation. It ensures accurate measurement and long-term reliability even under fluctuating static pressure and temperature conditions. Designed for accurate measurement of differential pressure, HPM81 provides a standard output of 4-20 mA DC and HART protocol compatibility, making it ideal for seamless integration into various control systems. With its innovative design and good functions.

In addition, it can be made into an explosion-proof version with an explosion-proof grade of Ex ia II CT6 Ga.
