Daikin-McQuay 330419603 Water Sensor
The Daikin-McQuay 330419603 Water Sensor is a precision 3K-MR thermistor engineered for heavy-duty chiller evaporator monitoring. Standard in many water-cooled chiller configurations, this evaporator leaving water sensor provides real-time temperature feedback to the main control board to manage the approach temperature and prevent freeze-up conditions. High-accuracy temperature sensing is critical in HVAC refrigeration loops to ensure the compressor modulates correctly based on the chilled water loop setpoint. This specific thermistor assembly features a 30-foot cable length, providing the necessary reach for remote mounting on large-scale industrial Daikin-McQuay units. By monitoring the leaving water temperature, the system can protect the heat exchanger and maintain maximum thermal efficiency. This part is a direct OEM replacement for legacy part numbers T2392-30, 073012003, and 12900150, ensuring zero-latency communication with the factory building management system (BMS).
Key Benefits- Direct OEM Compatibility: Ensures immediate integration with Daikin and McQuay chiller controllers without calibration offsets.
- Extended 30-Foot Reach: The pre-terminated 30' cable simplifies routing through complex mechanical rooms and panel conduit.
- High-Precision Resistance: The 3K-MR thermistor element provides a tight tolerance for accurate leaving water delta-T calculations.
- System Protection: Critical for detecting low water temperature alarms to prevent evaporator tube icing and catastrophic failure.
- Does this replace the T2392-30? Yes, the 330419603 is the current manufacturer-specified replacement for T2392-30 and 073012003.
- What is the resistance curve for this sensor? This is a 3K ohm at 25°C (77°F) thermistor, specialized for McQuay refrigeration applications.
- Can the 30-foot lead be shortened? While possible, it is recommended to coil excess lead to maintain the integrity of the factory shielding and resistance values.
