FDPFM – Differential Pressure Indicator For Hazardous Locations

Model : FDPFM


Description :

Differential Pressure Indicators are Digital Readout alternative for Gauges suited for application in Laminar Air Flow Cabinets, Clean Rooms, Biosafety Cabinets, AHUs, etc. in Hazardous locations

Differential Pressure Indicators are part replacement for the Analog Differential pressure Gauges & are easy to use with a clear 3 digits LED Display. It comes with a built-in sensor & also a buzzer alarm with an acknowledgment facility for process violation alert.

Salient features include Unit Conversion at the press of a key between mm. W.C. & Pascals, integrated buzzer alarm for set point violation, Offset provision to meet Audit requirements, analog 4-20mA Output for Clean Room Modular Wall Fitment & RS 485 Modbus communication for BMS / SCADA/PLC integration.
