Differential Pressure Transmitter Differential Pressure Transmitters are pressure transmitters designed for HVAC , Pharmaceutical Clean Rooms, Hospital Room applications, kitchen hoods, etc. where precise & low pressure measurements are critical. The D.P. Transmitter has 2 pressure ports for measuring the differential pressure across 2 measurement points . Alternatively it can be used as a static pressure transmitter by venting one pressure port to atmosphere Pressure Measuring Range : 0.0 to 0.1, 0.25, 0.50, 1.00, 2.00, 5.00 In. W.C. 0.0 to +25.0/+50.0/100.0/250.0/1000/5000 mm. W/C 0 to 10, 25, 50, 100, 250, 500, 1000 upto 9999 Pascals -100.0 to +100.0 mm.W.C., -50.0 to +50.0 mm.W.C. - 25.0 to + 25.0 mBar, 0.0 to 100.0 mBar 0.0 to 500.0 mBar, 0 to 1000 mBar (Any other range- Factory set as per customer specifications) Maximum Over Pressure : 2 Times the rated pressure Display : Not provided ( Contact factory for optional display ) Power : 24 Volts D.C. , 200 mA Output : 2 Wire 4–20 mA D.C.
