Daikin-McQuay 910153379 Pressure Transducer

The Daikin-McQuay 910153379 Pressure Transducer is a critical OEM replacement part engineered for precise suction-side monitoring in high-performance HVAC systems and chilled water systems. Designed to provide real-time refrigerant pressure sensing, this low pressure transducer operates with a standard 0-350 PSI range (P158-5204-01), converting physical pressure into accurate electrical signals for the system controller. This component is essential for maintaining compressor health and preventing low-pressure trip conditions that lead to downtime. As a veteran-grade field-serviceable part, the 910153379 is the direct technical replacement for discontinued models 331764501 and 331764511, ensuring 1:1 compatibility with legacy McQuay chillers and Daikin air handling units without the need for additional bracket modifications or re-wiring in most standard configurations.

• Direct OEM Compatibility: Seamlessly replaces obsolete part numbers 331764501 and 331764511 for fast HVAC system diagnostics and repair.
• Precision Monitoring: High-accuracy 0-350 PSI sensing allows for tight control over superheat and evaporation cycles.
• Rugged Construction: Built to withstand the vibration and thermal cycling common in industrial process control and heavy-duty refrigeration applications.
• Signal Stability: Delivers consistent voltage output to eliminate "ghost" error codes on Daikin VRV or McQuay MicroTech controllers.

Common Questions

Is the 910153379 compatible with all refrigerants?
This pressure sensor is specifically designed for standard HVAC refrigerants typically found in Daikin McQuay chillers and condensing units; verify compatibility with specific synthetic oils and high-pressure blends before installation.

Does this part require a new wiring harness?
When replacing a legacy transducer, it is a best practice to inspect the 3-pin connector for corrosion. This unit typically utilizes the existing low-pressure transducer lead to interface with the main control board.

How can I verify if this transducer is failing?
Technicians should check the DC voltage output at the controller and compare it to the system's manifold gauge pressure using a standard pressure-to-voltage conversion chart found in Daikin technical manuals.
