MAMAC Systems TE-702-B-17-D 12" Duct Temperature Sensor 20K Ohm

The MAMAC Systems TE-702-B-17-D Duct Mounted Temperature Sensor is a heating control component used to measure air temperature within ventilation ducts, and related mechanical equipment. It uses a 20k ohm temperature coefficient thermistor with a 12-inch probe that is installed directly into ductwork to detect airflow temperature changes. It provides resistance-based output that is interpreted by building automation controllers for regulating heating and cooling performance in commercial HVAC systems. It is mounted through duct walls or panels to support monitoring and control of supply or return air conditions within ventilation management systems.
