Maxitrol TS214B Temperature Sensor

The Maxitrol TS214B is a high-precision Dual Discharge Air Temperature Sensor engineered specifically for Selectra Series 14 and Series 44 gas flame modulation systems. This veteran-grade component is critical for direct-fired make-up air units, offering dual-range sensing capabilities at 55°F to 90°F and 120°F to 170°F. Designed for housing within a mixing tube, the TS214B averages the stratified airstream to provide accurate feedback to the amplifier, ensuring stable gas flow control without the lag associated with traditional mod motors. It is a direct fit for industrial applications like paint spray booths or door heaters where rapid switching between setpoints is required. The TS214B works in tandem with Maxitrol TD114B selectors and A1014 amplifiers to maintain consistent discharge temperatures. Built for the rigors of the mechanical room, this sensor features a robust thermistor design that interfaces seamlessly with M411, M511, and MR212 modulating valves for precise thermal management.

• Dual-Range Versatility: Supports both low-range 55-90°F and high-range 120-170°F setpoints for multi-stage processes.
• System Compatibility: Fully compatible with Selectra Series 14 and 44 electronic modulation systems.
• Enhanced Accuracy: Integration with an MT-series mixing tube eliminates temperature stratification errors.
• Rapid Response: Provides instantaneous electronic feedback for smoother modulation compared to mechanical alternatives.
• Industrial Durability: Engineered for direct-fired heating environments with an operating range of -40°F to 125°F.

What systems is the TS214B compatible with?
It is primarily used in Maxitrol Selectra Series 14 and 44 systems. It must be paired with selectors and amplifiers that share the same suffix and temperature range to ensure proper calibration.

Does this sensor require a mixing tube?
Yes, for accurate discharge air temperature sensing, the sensor should be installed within a Maxitrol mixing tube (such as the MT1 or MT2 series) to ensure it samples an average of the duct air.

How do I troubleshoot a TS214B sensor?
Technicians can verify the circuit by replacing the sensor with a 10,000-ohm, 1/2-watt test resistor at the amplifier terminals. If the system modulates correctly with the resistor, the sensor or its wiring is likely faulty.
