Air flow switches

Air Flow Sensors Based on the Calorimetric Principle for Air or Gaseous Media. Compact
















vent-captors are compact, self-contained flow sensors that work according to a calorimetric principle. The principle allows for the creation of compact, reliable flow sensors with a price/ performance ratio not possible with other physical flow-sensing principles.
Especially at a low flow rate, no other sensing principle can achieve the high accuracy of a vent-captor.
First engineered by weber Sensors more than 20 years ago, weber continues to pioneer sensors based on this principle.




vent-captors are available as insertion and in-line types. Both are also available with a binary output as switches and adjustable set-point and with an analog output as meters with an adjustable measuring range.
