The XTP Differential Pressure Sensor is an external pressure transducer that monitors pressure in the vertical common vent.

The transmitter uses a patented Si-Glas™ variable capacitance sensor. This MEMS sensor provides extraordinary sensitivity and long term stability. New digital compensation is accomplished using a highly reliable application specific integrated circuit (ASIC).

The transducer converts measured pressure into a corresponding voltage, which is then relayed to the control to modulate the damper position and/or fan speed – thus regulating pressure at the set-point.
