Filter Display Unit FDU
Filter Display Unit FDU
The Filter Display Unit FDU can measure/ display differential pressure for up to three Filters using inbuilt sensors and is designed to give fast & accurate display of differential pressure across the Filters. FDU has up to 3 dedicated 4-digit seven-segment, 0.56” Red LED displays to display PRE, FINE and HEPA Filters readings.
FDU has an inbuilt buzzer for audible alarm on Filter set point exceedance, the Filter display also blinks on set point exceedance for operator’s attention. It has RS485 communication port with MODBUS-RTU protocol for interfacing with PLC/DCS/SCADA systems. It has two digital inputs to indicate the AHU ON-OFF/TRIP status. The unit comes with free utility software for configuration and calibration. FDU is a cost effective replacement for analog mechanical pressure gauges.
The Filter Display Unit (FDU) is a device which can measure/display diferential pressure across the 3 filters of an AHU. With built-in digital sensors, it is designed to give fast and accurate display of differential pressure across the PRE, FINE, and HEPA filters of an AHU. It has up to 3 dedicated 4-digit seven segmet, 0.56″ Red LED displays to display the differential pressure reading across the three (03) filters.
FDU has an inbuilt buzzer for audible alarm on Filter set point exceedance, the filter display also blinks on set point exceedance for the operator’s attention.
It has RS-485 communication port with MODBUS-RTU protocol to interface with PLC/DCS/SCADA systems. The unit comes with free utility software for configuration ad calibration. FDU is a cost effective replacement for analog mechanical differential pressure gauges.
Masibus FDU is use for DP indicator,Differential pressure indicator,multi channel DP indicator with AHU or any HVAC system to monitor filter healthiness with BMS system.
