Maxitrol TS120 Temperature Sensor

The Maxitrol TS120 Temperature Sensor is a high-precision OEM wall-mounted space sensor engineered for Maxitrol Selectra Series 20/30 and Series 21/31 control systems. Designed to provide accurate environmental feedback, this sensor is essential for maintaining proper burner modulation and stable thermal conditions in commercial and light industrial indirect-fired heating units. While the standard Selectrastat (T120) offers integral sensing and selection, the TS120 allows for remote space temperature sensing when paired with a standalone TD120 temperature selector.

This sensor operates within a 55°F to 90°F temperature range, ensuring efficient operation for atmospheric burner applications. For HVAC contractors, the TS120 is a direct OEM replacement for Maxitrol TS2003A, maintaining system integrity without requiring extensive recalibration. Its durable construction is built to withstand the demands of industrial environments, providing the Selectra amplifier with the precise resistance signals needed to manage modulating gas valves like the MR410, MR510, or MR610 series.

Key Benefits

• Precise Burner Modulation: Delivers accurate ambient temperature data to Selectra amplifiers, preventing rapid cycling and ensuring consistent discharge air temperatures.
• System Versatility: Fully compatible with Series 20 (single furnace) and Series 30 (multiple furnace) configurations.
• Remote Sensing Capability: Ideal for applications where the temperature selection dial must be located away from the actual sensing area.
• OEM Reliability: Genuine Maxitrol replacement part ensures full compatibility with existing atmospheric burner control strings.
• Broad Environmental Limits: Engineered to function reliably in ambient conditions ranging from -30°F to 125°F.

Common Questions

Is the TS120 a direct replacement for the Selectrastat T120?
The TS120 is a remote temperature sensor only. To replace a T120 Selectrastat, which includes both a sensor and a selector dial, you would typically use the TS120 sensor paired with a TD120 selector.

What systems are compatible with the TS120?
It is designed for Maxitrol Selectra Series 20, 21, 30, and 31. It is commonly used in indirect-fired furnaces and make-up air units requiring space temperature control.

Does this sensor include the mixing tube?
No, the mixing tube is not included with the TS120 wall-mounted sensor. Mixing tubes are typically required for duct-mounted sensors (TS121/TS211) rather than wall-mounted space sensors.

Note: Mixing tube not included. Always verify system compatibility before ordering. Professional installation recommended.
