The WCPS300-MH73 series hydrogen pressure sensor transmitter can quickly sense changes in pressure and can be optionally converted into outputs such as 4-20mA/0.5~4.5V/0~10V. The sensor has a range of 0~0.35, 0~200MPa, a nonlinear accuracy of 0.25%, and a comprehensive accuracy of 0.5%. It adopts a unique filtering algorithm and temperature compensation algorithm (compensating temperature -20~85 ℃), and has the advantages of high accuracy, stability, and reliability.
The WCPS300-MH73 series hydrogen pressure sensor/transmitter is widely used in PEM fuel cells, hydrogen refueling stations, hydrogen storage, hydrogen fuel gas, test benches, train brakes and other fields. It not only improves safety and energy efficiency, but also realizes automation and data-driven management, providing enterprises with more efficient, safe and sustainable safety solutions.
