The Maxitrol TS114E is a high-precision discharge air temperature sensor engineered for direct-fired make-up air systems. Designed to integrate seamlessly with Selectra Series 14 modulation controls, this 10,000-ohm thermistor provides the critical feedback loop required for stable gas flame modulation. It operates within a specialized 100-250 degrees F range, making it the standard choice for industrial HVAC temperature control applications requiring higher discharge setpoints. By utilizing this sensor in conjunction with a Maxitrol mixing tube, technicians can ensure an accurate average air temperature reading, preventing the hunting or erratic firing common in poorly sensed streams. This OEM temperature sensor is compatible with Maxitrol modulator-regulator valves, including the M411, M511, and M611 series. Its rugged construction facilitates reliable performance in demanding environments, ensuring that gas-fired heating equipment maintains consistent output without the mechanical lag found in traditional mod motors. For contractors performing retrofits or repairs, the TS114E is essential for meeting ANSI Z83.18 engineering specifications for discharge air regulation. Key Benefits Enhanced Precision: Delivers instantaneous response to temperature fluctuations, ensuring stable air temperatures. Broad Compatibility: Specifically designed for Series 14 systems and direct-fired equipment. Rugged Durability: Built with high-quality materials to resist corrosion in industrial HVAC environments. Optimized Mixing: When used with a mixing tube, it provides an accurate representative sample of the discharge air stream. Common Questions What is the resistance of the TS114E sensor? The TS114E is a 10,000-ohm sensor at 77°F. Resistance decreases as the temperature increases, allowing the Selectra amplifier to modulate the gas valve based on the discharge air temperature. Can I use the TS114E without a mixing tube? It is highly recommended to use a Maxitrol mixing tube (such as the MT1 or MT2 series) to ensure the sensor captures a blended average of the air temperature rather than a localized hot or cold spot. How do I troubleshoot a TS114E sensor? Check for an open or short circuit in the wiring. You can verify functionality by measuring the DC voltage at the amplifier terminals; erratic readings often indicate improper sensor location or induced voltage from nearby high-voltage lines.
