Features Designed for VAV discharge air temperature sensing. Comes with 12 feet of plenum rated cable and 1/4" quick disconnects for ease of installation to any VAV controller. 304 SS thin wall probe with a cold rolled hermetically sealed end forms a monolithic encapsulation cavity for the sensor and is immune to failures caused by high humidity, contamination, thermal shock and vibration. The flat probe end provides a large thermally sensitive area and the sensor is in direct thermal contact to this surface. As a result, extremely fast response is achieved to changes in temperature. Probe is crimped to the flange using a patented process to provide a rugged, reliable and low profile attachment for ease of installation. More than 15 types of interchangeable NTC thermistors, precision platinum, nickel or balco RTDs are available for universal compatibility.
