| vent-captor | Air Flow Sensors Based on the Calorimetric Principle for Air or Gaseous Media. Compact, Precise, Rugged and Reliable 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. |  | | | | Insertion Type Air Flow Switches |  | Sensors to be connected to an existing pipe or duct by means of a nipple, collar or a welding fitting. They have switching outputs. | | Insertion Type Air Flow Meters | | Sensors to be connected to an existing pipe or duct by means of a nipple, collar or a welding fitting. They feature analog outputs. | | Inline Type Air Flow Switches | | Sensors especially suitable for monitoring small flow quantities. The sensor element is integrated into the sensor tube, avoiding restrictions of flow and/or pressure drops.
