The Maxitrol TS144 is a precision-engineered discharge air temperature sensor designed specifically for integration with Selectra modulation systems. This dual-range thermistor serves as the primary feedback loop for the gas valve, ensuring optimal burner adjustment based on real-time discharge temperatures. Functioning within a 40°F to 80°F minimum and 80°F to 140°F maximum range, it provides the critical data required for Selectra air temperature control in industrial and commercial make-up air applications. Technicians should note that this sensor is intended for installation within a mixing tube to ensure laminar airflow across the element, preventing erratic signal fluctuations and short-cycling of the indirect fired burner. Its rugged construction resists the thermal stressors common in high-static environments, maintaining calibration accuracy for long-term HVAC temperature regulation. When replacing a Maxitrol temperature probe, verify the resistance curve matches your specific amplifier or Selectra controller to ensure seamless system communication and modulation accuracy. Key Technical Benefits Dual-Range Versatility: Supports a broad temperature spectrum, accommodating both low-limit and high-limit discharge setpoints. Precise Modulation Feedback: Interfaces directly with Selectra systems to provide instantaneous resistance changes for smooth burner modulation. Mixing Tube Compatibility: Specifically designed for stable mounting in air streams, reducing the impact of turbulence on sensor readings. Field Reliability: High-grade thermistor element designed for the rigorous duty cycles of industrial HVACR equipment. Common Technician Questions Where should the Maxitrol TS144 be installed? This sensor must be mounted in the discharge air stream, ideally within a mixing tube located down-stream of the blower to ensure a representative air sample is measured. Does this sensor work with all Maxitrol Selectra systems? The TS144 is compatible with specific Selectra series. Always verify the resistance-to-temperature requirement of your specific modulating valve and amplifier combination. Can the TS144 be used for space sensing? No, this is a discharge air sensor. For space sensing applications, a dedicated room thermostat or remote setpoint controller should be utilized.
