Maxitrol TS114J Temperature Sensor

The Maxitrol TS114J is a high-precision discharge air temperature sensor engineered for direct-fired make-up air applications. Designed to interface seamlessly with the Selectra Series 14 modulation system, this thermistor-based component monitors airflow at the discharge point to provide real-time feedback to the electronic amplifier. It operates within a specific temperature range of 110°F to 160°F, making it ideal for industrial heating processes and commercial ventilation where higher discharge setpoints are required. For accurate sensing, the TS114J must be mounted within a mixing tube, such as the MT1 or MT2 series, to ensure the element is shielded from radiant heat and exposed to a representative cross-section of the air stream. In Series 14R configurations, this sensor facilitates the instantaneous response of modulator-regulator valves, maintaining stable discharge temperatures without the hunting or lag associated with mechanical dampers. When servicing, verify that the sensor resistance matches the TD114J remote selector or integral amplifier dial to prevent system calibration errors.

• System Compatibility: Purpose-built for Maxitrol Selectra Series 14 and 14R control circuits, ensuring plug-and-play integration with M or MR series valves.
• Operational Stability: Eliminates rapid cycling by providing continual gas flow adjustment based on precise discharge air temperature sensing.
• Optimized Heating Range: Specifically calibrated for the 110°F to 160°F range, filling the gap for high-temp make-up air and industrial oven needs.
• Reliable OEM Performance: Designed as a direct replacement part, maintaining the original engineering specifications for 10,000Ω @ 77°F resistance curves.

• Which mixing tube is required for installation? The TS114J is typically installed in an MT1-series mixing tube (available in lengths from 6" to 57") to protect the sensor and ensure an accurate average temperature reading across the duct.
• How do I verify if the sensor is faulty? Measure the resistance across the sensor leads with the wiring disconnected. For a Series 14 sensor, the resistance should be approximately 10,000 ohms at 77°F, decreasing by roughly 42 ohms for every degree the temperature rises.
• Can I use this with a 55-90°F selector? No. The temperature range of the sensor (TS114 or TS214) must match the range of the remote selector (TD114) or the integral dial on the amplifier to ensure proper gas flame modulation.
