Carrier HH79NZ013 Temperature Sensor

The Carrier HH79NZ013 Temperature Sensor is a high-precision OEM thermistor assembly designed for critical monitoring in industrial and commercial HVACR applications. As a direct replacement for the obsolete HH79NZ037 and HH79NZ003 models, this clamp-on temperature probe ensures seamless integration with existing control logic without requiring invasive pipe modifications. Engineered for the Carrier 30GB-200-550 chiller series and compatible 48JK/500 models, it provides real-time resistance feedback to the main controller, preventing frost formation and optimizing compressor modulation. The ruggedized HVAC temperature sensor housing is purpose-built to withstand the high-vibration environments of mechanical rooms while maintaining accurate thermal conductivity across fluid lines. This factory authorized part is essential for technicians looking to resolve communication faults or sensor out-of-range errors in large-scale cooling plants and process water systems.

• Direct OEM Replacement: Replaces HH79NZ037 and HH79NZ003 with exact electrical specifications for plug-and-play installation.
• Non-Invasive Clamp-On Design: Secures firmly to piping for accurate surface temperature readings without the need for system drawdown or hot work.
• Enhanced System Reliability: Delivers precise thermistor feedback to the control board to manage defrost cycles and head pressure effectively.
• Broad Industrial Compatibility: Specifically sized for Carrier 30GB chiller series and commercial air handlers.

Is this sensor compatible with non-Carrier equipment?
This 10k ohm nominal thermistor is specifically calibrated for Carrier industrial controllers, particularly the 30GB-200-550 series. Using it with non-Carrier boards may result in inaccurate temperature scaling.

Does the HH79NZ013 require special thermal paste for installation?
While the clamp provides sufficient mechanical contact, veteran technicians recommend a thin layer of high-conductivity thermal grease between the probe and the pipe for the fastest response times.

Can this be used as a replacement for the HH79NZ037?
Yes, the HH79NZ013 is the official superseding part number for the HH79NZ037, maintaining the same resistance-to-temperature curve required by the system firmware.
