The Series AVG Averaging Temperature Sensor provides a cost effective solution for HVAC system temperature control. Measure average supply air temperature in large ducts or plenums with the Series AVG. The sensors are designed with a 3/8" (9 mm) diameter bendable aluminum casing terminating into a painted steel, NEMA 4 (IP 65) enclosure. Four environmentally sealed sensor modules are evenly spaced throughout the length of the casing. Select platinum RTD or thermistor modules.
