The Series TE-A Averaging Temperature Sensors are used to measure the temperature in large ducts and air handler units. Bendable aluminum capillaries are available in 6-, 12- and 24-foot lengths. These capillaries consist of four thermistor or RTD sensors, which are internally averaged to give a single output signal. Series CC1 mounting brackets are available to mount the capillary to the wall of the duct or air handler without kinking the sensor wires inside the probe. For faster installation, the temperature sensor enclosure has multiple knockouts, wide mounting ears and a screw-off captured lid.
