York 025-29964-001 Water Temperature Sensor: Core Functions
1. Precise Water Temperature Monitoring (The Core of Control)
High-Precision 3K NTC: Features a resistance of 3000Ω at 25°C; resistance changes by approximately 4% for every 1°C change in temperature. The signal is linear and stable, with an error margin of ≤ ±0.2°C.
Dual Inlet/Outlet Monitoring: Simultaneously measures the inlet and outlet temperatures of both chilled water and cooling water. It calculates temperature differentials and approach temperatures to assess heat exchange efficiency, verify normal water flow, and detect potential scaling or blockages.
Wide Temperature Adaptability: Covers a broad range of -40°C to +120°C, encompassing all operating conditions—including unit startup, running, shutdown, and anti-freeze modes—ensuring stable measurement across all four seasons.
2. System Protection and Safety (The Core of Safety)
Anti-Freeze Protection (Critical): Monitors the chilled water outlet temperature; triggers an alarm if the temperature drops below 5°C and initiates an emergency shutdown if it falls below 3°C, thereby preventing evaporator freezing and potential pipe rupture.
High-Temperature Protection: Monitors the cooling water outlet temperature; initiates load reduction or a system shutdown in the event of overheating to prevent excessive condensing pressure and compressor overload.
Water Flow Anomaly Protection: Issues a warning regarding insufficient water flow, pump failure, or pipe blockages if the temperature differential between the inlet and outlet becomes excessively large (>8°C) or excessively small (<2°C).
3. Energy Efficiency Regulation and Fault Diagnosis (The Core of Stability)
Precise Capacity Regulation: Works in conjunction with the inlet guide vanes on York centrifugal chillers (or slide valves on screw chillers) to adjust cooling capacity in real-time based on water temperature, resulting in energy savings of 10–15%.
Fault Pre-Warning: Provides early alerts in cases of temperature drift or abnormal fluctuations, serving as a pre-warning for potential issues such as sensor aging, probe scaling, cable damage, or control system malfunctions.
Data Closed-Loop Integration: Compatible with York’s MicroGateway, CH530, UC800, and IVU control systems. Enables real-time uploading of temperature data, remote monitoring capabilities, and historical data traceability. 4. High Reliability and Long Lifespan (Durable Core)
Red Copper Probe: Features rapid thermal conductivity, corrosion resistance, and scale resistance; remains rust-free and uncorroded even after prolonged immersion in water, ensuring stable measurements.
NTC Chip: Offers high sensitivity, excellent stability, and minimal temperature drift; ensures zero-point stability and no signal attenuation over extended periods of use, with a service life of ≥5 years.
Waterproof and Moisture-Proof Design: IP67 rated protection; features oil-resistant and anti-aging cabling, along with a waterproof-sealed connector, making it ideally suited for the humid, dusty, and high-vibration operating environments typical of equipment rooms.

Common Product Faults and Replacement Indicators
1. Signal Anomalies (Most Common): Temperature readings drift, fluctuate significantly, go missing, or remain fixed/static. This manifests as frequent unit alarms, reduced cooling capacity, decreased energy efficiency, and failure of freeze protection mechanisms.
2. Physical Damage: Probe corrosion/scaling, damaged/aged cabling, or broken/water-ingress-affected connectors. This leads to inaccurate signal readings, short circuits, or open circuits.
3. Exceeding Service Life (≥ 5 Years): Chip aging, resistance drift, or seal failure. This poses risks of measurement inaccuracy, failure of safety protection systems, and potential freezing or physical damage to the unit; replacement is recommended.
4. Resistance Anomalies: The resistance value deviates from the standard 3000Ω ± 50Ω at 25°C, or the resistance value shows no significant change in response to temperature fluctuations; immediate replacement is required.
