The FRD Sensor FD820C Embedded Micro Differential Pressure Transmitter is designed for low-range differential pressure measurement in cleanrooms, HVAC systems, laboratories, medical facilities, and industrial air-handling applications.
With a compact embedded design, the FD820C provides stable differential pressure monitoring for applications where space is limited and reliable pressure feedback is essential. It can be integrated with PLC, HVAC control systems, DCS, and other automation platforms.
Typical applications include cleanroom pressure monitoring, FFU systems, air filter differential pressure detection, ventilation control, and isolation room pressure monitoring.
Micro differential pressure applications often face challenges such as limited installation space, unstable measurement, long-term accuracy drift and difficult system integration.
FD820C addresses these challenges with:
