Dwyer Instruments 122095-84 2-Wire Thermocouple Type J

The Dwyer Instruments 122095-84 2-Wire Thermocouple Type J measures operating temperatures across air handlers, heating units, and ventilation ductwork. Mounted within process air streams or heating zones of HVAC systems, the joined different wires generate a millivolt signal proportional to temperature fluctuations at the sensing junction. Transmitting this thermoelectric feedback to connected instruments or control boards enables continuous monitoring of thermal conditions. Providing fast temperature tracking allows system controllers to regulate heating sequences, execute safety shutdowns, and support environmental temperature management.
