0.5% Accuracy, NEMA 4X (IP66) Enclosure
Wet/Wet Differential Pressure Transmitter monitors differential pressure of air, liquids, and gases. Applications include flow elements, heat exchangers, filters, coils, and pumps.
Features
-
Powered by either DC or AC - take advantage of most readily available power source reducing installation costs
-
Optional LCD does not need a separate power supply - lowers installed cost
-
Selectable voltage range - provides flexible choice for changing design or inputs for process/HVAC controllers being used to monitor and control
-
Push button zero (versus trim pot) - more simple zeroing provides easy install and calibration reducing installation time and possibility of operator error
-
Optional LCD indicator provides local status to identify operational condition
-
Remote sensor option reduces installation labor and material
