Carrier 00PPG000008100 Temperature Sensor / NTC Thermistor-type Water Temperature Probe – Monitors Chiller Inlet and Outlet Water Temperatures

Carrier 00PPG000008100 Temperature Sensor / NTC Thermistor-type Water Temperature Probe – Monitors Chiller Inlet and Outlet Water Temperatures

The 00PPG000008100 is a Carrier NTC thermistor-type water temperature sensor, serving as a standard, core temperature-sensing component for 30RB/30RQ air-cooled scroll heat pumps and 30XA/30XW/30XQ water-cooled screw chillers.
Featuring an integrated stainless steel probe and a durable, weather-resistant shielded cable, it is designed to monitor the inlet and outlet temperatures of chilled or cooling water. It transmits real-time temperature-resistance signals to the main control board, providing critical data for compressor start/stop operations, load regulation, water flow monitoring, freeze protection, and cooling/heating mode switching. This sensor is a frequently replaced consumable in commercial central air conditioning maintenance and is compatible with Carrier screw and scroll chiller systems.

Core Functions and Features:
1. Real-time Chilled/Cooling Water Temperature Monitoring: Measures the temperature difference between supply and return water to calculate cooling capacity and match compressor load, enabling energy-efficient variable-frequency control.
2. Low-Temperature/Anti-Freeze Protection: Triggers continuous water pump operation and activates electric heating when the water temperature drops below the anti-freeze threshold, preventing water pipes from freezing and bursting in winter.
3. High-Temperature Overload Protection: Reduces compressor load or shuts down the unit when the return water temperature becomes excessively high, preventing high-pressure and high-temperature faults.
4. Water Flow Logic Interlock: Works with the water flow switch to assess water circulation based on temperature changes; disables unit operation if no water flow is detected.
5. Automatic Cooling/Heating Mode Switching: Heat pump models determine the operating mode (cooling or heating) based on water temperature and adjust the control logic for fans and expansion valves.
6. Fault Self-Diagnosis and Alarm: Issues a water temperature sensor fault code in the event of probe disconnection, short-circuiting, or resistance drift, facilitating rapid troubleshooting and maintenance.

Product Structural and Material Advantages:
1. Stainless Steel Sealed Probe: Features an integrated, seamless encapsulated thermal sensing core; waterproof and rust-resistant; withstands long-term immersion in antifreeze without corrosion; offers rapid thermal conductivity and quick temperature response.
2. Brass Mounting Base: Threaded design fits standard unit thermowells for easy installation and removal; ensures uniform heat conduction and eliminates temperature measurement lag.
3. Double-Shielded Cable: Built-in shielding layer isolates electromagnetic interference from variable frequency drives (VFDs) and contactors, preventing temperature reading fluctuations and false alarms.
4. High/Low-Temperature Resistant Sheath: Specialized gray refrigeration-grade cable; remains flexible and crack-free at -40°C; resists aging and embrittlement in high-temperature equipment rooms or under direct outdoor sunlight.
5. Fully Sealed Potting Process: High-temperature epoxy seal at the probe tail prevents the ingress of condensation or oil, which could otherwise cause sensor short-circuits or failure, thereby extending service life.
