Trane TDR0731 Transmitter
The Trane TDR0731 Transmitter is a precision low pressure transducer designed for critical monitoring in high-performance HVAC systems. This OEM Trane part features a standardized 2-10VDC analog output proportional to a sensing range of 0-20 inches of water column (wc). Engineered for BAS integration and VAV box control, it provides high-accuracy differential pressure measurements essential for maintaining proper airflow management and system static pressure.
Built with a reliable 1/5-inch barbed fitting, the TDR0731 ensures a secure connection to standard 1/4-inch pneumatic tubing. For veteran technicians, this component is a drop-in replacement for failed air pressure sensors, offering a linear voltage signal that allows microprocessor controllers to adjust fan speeds or damper positions with zero-drift stability. Its robust construction is tailored for long-term industrial heating and cooling applications where precise air pressure regulation is non-negotiable.
Key Benefits
- Compatible with Trane HVAC equipment utilizing a 2-10VDC signal.
- Precise 0-20"wc pressure range for sensitive static and differential air monitoring.
- OEM reliability ensures consistent resistance values and signal accuracy over the full operating cycle.
- Simplified installation via barbed pneumatic ports for fast field replacement.
- Enables energy-efficient VFD control by providing real-time duct pressure data.
Common Questions
What is the signal mapping for the TDR0731?
The unit outputs a linear 2VDC at 0"wc and scales up to 10VDC at 20"wc, allowing for precise transducer troubleshooting using a standard voltmeter.
Can this be used for refrigerant pressure?
No, this is a low-pressure air transducer specifically calibrated for water column measurements in air systems, not for high-side or suction-side refrigerant pressures.
What happens if the output stays at 0VDC?
An output below 2VDC typically indicates a loss of 24V power to the sensor or a wiring fault in the control circuit, rather than an out-of-range pressure condition.
