Maxitrol TS214G Sensor

The Maxitrol TS214G Sensor is a precision discharge air temperature sensor designed for integration with Maxitrol Selectra systems. This dual-range thermistor monitors air stream temperatures to provide essential feedback for gas-fired modulation controls. Engineered for versatility, it supports 55°F to 90°F and 90°F to 140°F operating ranges, making it a critical component for indirect-fired makeup air units. When paired with a mixing tube, the TS214G ensures accurate air sampling and stable discharge temperatures. Field technicians rely on its consistent resistance-to-temperature curve to maintain strict environmental tolerances in commercial HVACR applications. Replacing a faulty sensor with an authentic TS214G prevents erratic burner behavior and ensures the system maintains the desired HVAC discharge air temperature setpoint. Proper installation within the air stream is required to avoid stratification issues and ensure rapid thermal response.

• Dual-Range Versatility: Supports both standard and high-temperature discharge air requirements in a single footprint.
• High-Precision Monitoring: Delivers accurate resistance feedback to Maxitrol Selectra modulating valves for tight temperature control.
• Rugged Construction: Built for the high-velocity environments found in industrial makeup air sensors.
• Compatibility: Optimized for use with Maxitrol mixing tubes to ensure laminar flow over the sensing element.

What is the primary function of the TS214G sensor?
It monitors the discharge air temperature in a duct and sends a signal to the modulation control to adjust the gas flow to the burner.

Can the TS214G be used without a mixing tube?
While functionally possible, using a mixing tube is highly recommended to ensure the sensor reads a true average temperature rather than localized hot or cold spots.

How do I select between the 55-90F and 90-140F ranges?
The operating range is typically determined by the wiring configuration and the specific Maxitrol amplifier or controller it is connected to.
