York 025-28678-112 Transducer

The York 025-28678-112 Transducer is a precision-engineered OEM pressure sensor designed for accurate monitoring in industrial HVAC control systems. Operating on a 5VDC supply, this ratiometric transducer provides a linear output signal ranging from 0.5 to 4.5 VDC, calibrated for a stable pressure range of 6 to 74 PSI. As a critical component for York and Johnson Controls chiller assemblies, it facilitates real-time pressure feedback to the microprocessor, ensuring the system maintains precise setpoints for optimized refrigerant flow and compressor protection.

Constructed with a 1/2"-20 UNF-2A SAE external port and an Amp-style electrical connector, the York 025-28678-112 serves as a direct, drop-in replacement for the AKS32R transducer and P499REAT520C models. Its rugged design is built to withstand high-vibration environments and extreme thermal cycling typical in heavy-duty commercial HVAC maintenance. By integrating this authentic York replacement part, technicians can resolve fluctuating pressure readings and prevent unnecessary system shutdowns caused by signal drift or sensor failure.

Key Benefits:

• System Precision: Delivers high-accuracy pressure monitoring across a 6-74 PSI range for tighter control loops.
• Ratiometric Output: Features a standard 0.5 to 4.5 VDC signal for seamless integration with existing control logic.
• Direct Compatibility: Engineered as a genuine 025-28678-112 York replacement for specific chiller and oil pressure applications.
• Contractor Grade: Durable housing and 5 VDC input requirements meet stringent industrial specifications for longevity.

Common Questions:

What is the thread size for the York 025-28678-112?
This transducer utilizes a 1/2"-20 UNF-2A SAE external port, common in York chiller applications for secure, leak-free pressure sensing.

Can this be used for oil pressure monitoring?
Yes, the 025-28678-112 is frequently applied as an oil pressure transducer in centrifugal and screw compressor packages where precise low-pressure monitoring is required.

Does this part require calibration after installation?
While the York 025-28678-112 is factory-calibrated, technicians should verify the analog input at the control panel to ensure signal integrity across the wiring harness.
