Very-Low Differential Transducer; 0 to 1" Water ~ 4 to 20 mA Output

Uni- and bi-directional pressure measurement offer high accuracy for building energy management|Static accuracy of 1%|Fully protected against reverse wiring|Fire retardent case is UL 94 V-0 approved|Low-pressure transucers sense gauge or differential pressure and convert to a proportional output. Utilizing an improved stainless steel micro-tig welded sensor, positive pressure moves the diaphragm toward the electrode, increasing capacitance. A decrease in pressure moves the diaphragm away from the electrode, decreasing the capcitance. Change in capacitance is converted to a linear DC electrical signal through the transducer''s circuit. Transducers are designed for HVAC, air volume and fan control, static duct and clean-room pressures, and environmental pollution control.
