Maxitrol TS114G Sensor

The Maxitrol TS114G is a specialized discharge air temperature sensor designed for integration with Maxitrol Selectra Series 14 electronic gas modulation systems. This OEM replacement sensor is calibrated for a specific 90-140 degrees F operating range, providing high-accuracy thermal feedback to the amplifier and mixing tube assembly. In a typical commercial HVAC setup, the TS114G monitors the supply air stream and signals the modulating gas valve to adjust firing rates, preventing temperature overshoot and ensuring consistent discharge conditions.

Built for industrial duty, this thermistor-based temperature sensing element is housed in a rugged assembly to withstand high-velocity airflow and constant thermal cycling. When performing a system diagnostics check or field replacement, verify that the existing mixing tube is free of debris to ensure the TS114G maintains a linear resistance-to-temperature response. This sensor is essential for direct-fired make-up air units where precise discharge air temperature control is required for occupant comfort and equipment safety.

Key Benefits for Contractors

• Direct OEM Compatibility: Ensures the resistance curve matches the original system specifications, eliminating the need for recalibration.
• Durable Construction: Heavy-duty materials designed for commercial HVAC environments and high-cycle industrial use.
• Simplified Installation: Designed as a drop-in replacement for the Maxitrol TS114G within standard mixing tube configurations.

Common Questions

Is the TS114G compatible with Series 21 or 44 systems?
No, the TS114G is specifically calibrated for Series 14 gas modulation controls. Using this sensor with incompatible amplifiers will result in incorrect temperature readings and erratic gas valve behavior.

Does this sensor require a specific mixing tube?
Yes, for accurate discharge air temperature sensing, the TS114G must be installed within a compatible Maxitrol mixing tube to ensure the element receives a representative sample of the air stream.

How do I verify if the sensor is faulty?
Technicians should perform a resistance check across the sensor leads and compare the ohms against the Maxitrol Series 14 calibration chart for the current ambient temperature.
