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
