Product Brief Describtion：
The IP68 waterproof NTC temperature sensor is designed for reliable temperature monitoring in HVAC evaporator and refrigeration systems. Featuring a TPE overmolded probe structure, it provides excellent moisture resistance and protection against water ingress in demanding operating environments. Available in 10K and 100K resistance options, this NTC temperature probe is suitable for air conditioners, evaporators, cooling equipment and refrigeration applications. Custom resistance values, B-values, cable lengths and probe configurations are available to meet different OEM requirements.
Typical Application:
Commercial ChillerUsed for evaporator, water tank and pipeline temperature detection of industrial and commercial chillers. Provides accurate temperature feedback to the control board to realize stable cooling regulation and anti-freeze protection.
Ice Maker & Ice MachineMonitors evaporator and water temperature during ice making and harvesting cycles. Helps the controller judge ice formation status and automatically switch working modes to ensure consistent ice production.
Refrigeration SystemsSuitable for temperature collection on cooling loops inside refrigeration equipment. Reliable temperature signal output supports over-temperature alarm and normal operation protection of the refrigeration system.
Low Temperature Refrigeration EquipmentTPE overmolded structure maintains stable sensing performance in continuous low-temperature and humid environments. Ideal for long-term temperature monitoring of cold-type refrigeration devices.
Feature & Advantage
IP68 Waterproof GradeTPE overmolded integrated sealing structure, fully protected against water ingress, suitable for humid, wet and condensate-prone refrigeration environments.
High Precision NTC Thermistor10K resistance, B3950, ±1% tolerance, delivers consistent and accurate temperature readings for reliable system control.
