Fully protected against reverse wiring. 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.
