FD820CG Wall-Mounted Micro-Differential Pressure Transmitter | Integrated Monitor for Temperature, Humidity & Pressure in Clean Environments
The FD820CG wall-mounted micro-differential pressure transmitter is a high-performance device customized for micro-differential pressure detection in critical application environments. Integrating the latest digital technology in the field of sensor manufacturing, it completely solves the drift problem of small-range transmitters through precise digital temperature compensation and non-linear correction algorithms. The device supports simultaneous monitoring of multiple parameters: differential pressure (0-50Pa~2500Pa), temperature (0℃~60℃), and humidity (0%~100%RH), with high accuracy of 0.5%F.S/1.0%F.S and long-term stability of 0.2%F.S/year. Equipped with multiple output signal options (4-20mA, RS485, etc.) and MODBUS RTU protocol, it supports flexible wall-mounted or embedded installation, with optional Ex ia IIB T6 Ga explosion-proof configuration, serving as a reliable monitoring core for clean workshops, medical negative pressure environments and other scenarios.
