Product Overview

The Duwei DWH3 series differential pressure sensor module is a two-wire 4~20mA sensor module. It utilizes a high-performance MEMS pressure-sensitive chip and a dedicated conditioning chip, and employs a multi-segment compensation algorithm to achieve multi-stage temperature compensation for the sensor, reducing the impact of the environment on differential pressure output. It is widely used in air or neutral gas detection and control. It is suitable for gas pressure detection in various ventilation and air conditioning systems and equipment, as well as differential pressure detection applications in cleanrooms, laboratories, and gas pipeline filter resistance.
