Low range pressure transducers and transmitters for measuring draft air pressure in air handling systems.
Draft pressure sensors are used to measure the amount of vacuum or suction pressure generated by air moving or expanding through an air duct, ventilation shaft, flue or chimney.
Draft pressure is typically measured in inches of water column, millibar or pascals pressure units.
A draft differential pressure sensors has two ports for measuring the difference between two positions, across which the draft is generated.
A draft gauge pressure sensor will measure the draft pressure relative to the local atmospheric pressure, and depending on the installation can be configured as positive or negative gauge pressure sensor.
If the draft air can move in the reverse direction, then a differential or gauge reference pressure sensor can be scaled with a bi-directional range such as -6 to +6 mbar so that the draft air pressure can be measured in both directions.
