FDPRHT – Cleanroom Monitor For Hazardous Locations

Model : FDPRHT


Description :

The Clean Room Monitor is designed to measure the vital parameters of Temperature, Humidity & Differential Pressure in CleanRoom Applications. The Model FDPRHT is designed for minimum cabling & easy flush mounting in Modular Wall or Brick Walls of Clean Rooms. The sensors for all 3 parameters are integrated inside for ease of use& installation. The Model FDPRHT is available for Remote Sensors for humidity, temperature & integrated differential pressure. The 3 parameters are displayed on the instrument using external transmitters — Combined Humidity & Temperature Transmitter (HP1) and internal Differential Pressure Transmitter. Standout features in the Clean Room Monitor include integrated buzzer for parameter violation indication, individual LED for process violation, buzzer enable/disable feature & buzzer delay option and any other customized solution. The instruments find immense use in Pharma Clean Rooms, APIs, Bulk Drugs, Electronic Hardware Manufacturing Plants, Test Plants, Green Houses, etc. Easy integration to Building Management Systems (BMS ) & SCADA interfacing allow easy set up & great control.
