Trane TDR0645 Pressure Transducer
The Trane TDR0645 Pressure Transducer (also referenced as TDR00645) is a heavy-duty suction pressure sensor engineered for precise refrigerant circuit monitoring. This OEM Trane part provides a linear DC signal output, calibrated at 0.5 VDC at 14.7 PSIA (ambient atmospheric pressure) and scaling up to 4.5 VDC at 400 PSIA. Built for high-stakes HVAC system diagnostics, this transducer features a 1/4" SAE female flare fitting with an integrated internal deflator, ensuring a secure, leak-free connection to the suction line Schrader port.
Designed for multi-stage systems and commercial air handlers, the TDR0645 enables real-time pressure monitoring and control, allowing the EEV board to optimize superheat and prevent liquid slugging. The 72-inch lead wire configuration simplifies routing to the control module in large-scale industrial pressure monitoring layouts. Whether you are performing a Trane pressure sensor replacement or troubleshooting a low-voltage error code, this transducer delivers the high-ratio accuracy required for maintaining peak refrigeration efficiency.
Key Benefits:- Precise Signal Scaling: Specifically calibrated for 0.5 VDC output at 14.7 PSI, ensuring accurate atmospheric reference points for system calibration.
- Versatile Compatibility: Engineered as a direct OEM suction pressure transducer for a wide range of Trane and American Standard outdoor units and chillers.
- Rugged Field Construction: Features 7/16-20 UNF-2B threads and a compact, vibration-resistant housing built for high-duty cycle HVAC industrial systems.
- Integrated Safety: The female flare fitting includes a built-in deflator to facilitate installation without unnecessary refrigerant loss.
What is the standard voltage range for the TDR0645?
This transducer typically operates on a 5 VDC input from the controller, providing a linear output signal where 0.5 VDC represents 14.7 PSIA and 4.5 VDC represents 400 PSIA.
Is the TDR0645 used for high-side or low-side pressure?
The TDR0645 is primarily utilized as a suction pressure transducer for monitoring the low side of the refrigerant circuit to manage superheat and cooling staging.
Why is my controller reading 0 PSI when the transducer is connected?
If the sensor signal drops below the 0.5 VDC floor (e.g., 0 VDC), check for wiring harness damage or a failed 5V supply from the control board, as these are common points of failure in technical HVAC troubleshooting.
