Tubular Air Sensor with Cable

 General description

Tubular Air sensors are generally used where there is a requirement to measure the temperature inside an enclosed area (e.g. Air ducting) where the sensor measures away from the wall of the enclosure. The stainless steel tube offers protection and support of the sensor.

This style allows for a compression fitting for supporting the tube.
