This Rigid Duct Point Temperature Sensor measures 4" and provides input for cost-effective, accurate temperature sensing to the Modular Building Controller (MBC), Remote Building Controller (RBC), Stand-alone Control Unit (SCU), MPU and Terminal Equipment Controllers via an 18 AWG twisted, shielded cable pair.
The sensor resistance varies proportionally to the temperature being measured and has an 100,000 Ohm reference resistance at 77 Degrees Fahrenheit..
