Description
This duct averaging temperature sensor is designed specifically to measure air in stratified air such as the mixing section of an air handler. The air in a typical mixing section varies by position according to inlet temperatures and damper position.
A standard single point probe will not provide any sort of useful information. Therefore, this averaging probe solves the problem by measuring and averaging the temperature across nine evenly distributed points in the mixing section.
The duct averaging temperature sensor uses nine separate thermistors wired in a series parallel arrangement. The resulting temperature / resistance curve is the same as a standard single thermistor. Our usual stocking temperature curve is the 10k type2 which is compatible with all the major systems.
Averaging sensors come with a foam backed handy box and three different length probes from 12ft on up to 39 ft in length (3.5m to 12m lengths), Duct averaging temperature sensors should be mounted across the duct in a serpentine fashion with bends in a smooth arc using the included clips.

Further BackGround:
In mixed air sections within an air handler the air is stratified making it a challenge to accurately measure the temperature. Because the damper position and supply/return temperatures change, you cannot trust a simple single-point sensor. Any sort of sequence based on mixed air temperature will benefit from an averaging type sensor.
This sensor uses several single probes wired in the series/parallel configuration shown above. Moreover, the sensor responds with a standard 10k type 2 thermistor curve, making it compatible with all major control systems.
