Siemens 24" Platinum RTD Rigid Duct Averaging Temperature Sensor - 100 Ohm

100 ohm RTD sensors provide input for accurate loop powered temperature sensing (detecting) via a 20 AWG twisted, shielded cable pair. The loop current varies according to the temperature being measured. Several models are available for specific mounting and sensing applications. The temperature transmitter equipped Duct Averaging Sensor assembly senses the average air temperature in ductwork where mixing baffles are not provided or where stratification occurs. Each sensor assembly mounts on sheet metal ducts.
