Daikin-McQuay 336078351 Transducer
The Daikin-McQuay 336078351 Transducer is a mission-critical 0-350# PSR Transducer engineered for precise pressure monitoring in high-performance HVAC systems. Built for the rigors of industrial process control, this OEM component replaces legacy part numbers including 333992051, 331764511, and 331764521. Its low pressure transducer design utilizes a high-accuracy sensing diaphragm to convert refrigerant or fluid pressure into a stable electrical signal, typically 4-20mA, allowing for real-time adjustments by the system controller. The unit features a durable housing to withstand mechanical vibration and refrigerant pressure spikes common in Daikin chillers and boilers. Designed with a female flare connection, it ensures a secure, leak-free mechanical interface. When performing a field replacement on older equipment, it is standard practice to inspect the wiring harness for signs of wear; some installations may require a 3-conductor 22AWG shielded cable (such as the 336298104) to maintain signal integrity and mitigate electromagnetic interference in the mechanical room.
Key Benefits- Precise Pressure Sensing: Provides an accurate 0-350 PSIG range essential for maintaining optimal subcooling and superheat levels.
- Direct OEM Replacement: Seamlessly integrates with McQuay and Daikin chiller control boards without requiring recalibration of the logic controller.
- Rugged Construction: Engineered to hold calibration despite constant compressor vibration and thermal cycling.
- Enhanced System Protection: Enables rapid high-pressure or low-pressure safety cut-outs to prevent compressor damage and downtime.
Is this transducer compatible with all refrigerants?
This 0-350# PSR Transducer is designed for standard HVAC applications. Always verify that the wetted materials are compatible with the specific refrigerant and oil type used in your system.
What are the signs that a 336078351 transducer has failed?
Technicians should look for erratic pressure readings on the HMI, a "fixed" output signal regardless of actual pressure changes, or "No Signal" alarms indicating a short circuit or open loop in the wiring.
Do I need to replace the wiring harness with the sensor?
While not always required, if you are upgrading from an older NSK series, it is highly recommended to use a new 3-conductor shielded harness to ensure the electrical connection remains moisture-tight and free from signal noise.
