Trane SEN0999 Temp Sensor
The Trane SEN0999 is a high-precision mixed air temperature sensor engineered for commercial and industrial air handling units. Featuring a 15-foot capillary tube, this sensor is designed to provide comprehensive average temperature readings across the duct cross-section, preventing localized stratification from causing inaccurate system cycling. This OEM Trane replacement is critical for economizer control and maintaining discharge air setpoints within tight tolerances, especially in ReliaTel controlled units where the mixed air temperature (MAT) input is a primary requirement for reference enthalpy or dry bulb operations.
Built with a durable aluminum construction and finished in a high-visibility blue color for easy identification during field service, the SEN0999 operates reliably across a wide thermal range from -40°F to 158°F. The 10kΩ thermistor output integrates seamlessly with existing building automation systems (BAS) and zone controllers, allowing for cascade proportional-integral control loops to manage heating and cooling hydronic coils. Replacing a drifted or contaminated sensor with this authentic Trane part ensures the system avoids low-limit trips and maintains the 45°F MAT threshold essential for protecting equipment against potential freezing conditions.
Key Benefits- 15-Foot Capillary Reach: Enables wide-area sensing to eliminate errors caused by air stratification in large return air plenums.
- Precise Thermistor Accuracy: Provides a 10kΩ signal compatible with standard Trane HVAC controls and economizer actuator modules.
- Rugged Aluminum Housing: Resists moisture and airborne contaminants typical in industrial environments to prevent signal drift.
- Standard Receptacle Connector: Simplifies field installation by matching factory wiring harnesses for quick "plug-and-play" replacement.
Is the SEN0999 a direct substitute for previous sensor models?
Yes, the SEN0999 (often identified by the SEN00999 kit number) is a genuine replacement for older mixed air sensor versions and is confirmed to fit a wide array of Trane commercial rooftop units.
What are the symptoms of a failing mixed air sensor?
Technicians frequently see "8 Flash" error codes on the RTEM or economizer modules, incorrect -40° or +158° readings in the BAS, or the system locking in minimum position due to a false 45°F low-limit diagnostic.
Can the capillary be cut to length?
No, the 15-foot capillary should be routed or coiled if the full length is not required; cutting the tube will destroy the sensing element and lead to immediate component failure.
