Maxitrol TS194Q Sensor

The Maxitrol TS194Q Sensor is a high-sensitivity thermistor designed for precision temperature monitoring in Series 94 Selectra modular systems. Engineered specifically for use with a Maxitrol mixing tube, this quick response sensor provides the rapid thermal feedback necessary for stable discharge air control in high-performance HVACR applications. For contractors managing industrial gas burners or direct-fired make-up air units, the TS194Q ensures the electronic modulation system maintains strict setpoint accuracy by minimizing thermal lag. Its compact probe design allows for seamless integration into the airstream, facilitating immediate resistance changes that inform the amplifier and modulator valve configuration. Standardizing on the TS194Q temperature sensor within a Maxitrol Selectra setup prevents hunting and ensures consistent combustion efficiency across varying load conditions, making it a critical component for gas pressure regulation and climate control maintenance.

Technical Key Benefits

• Optimized Response Time: Engineered as a ?? response sensor to provide near-instantaneous feedback to the Selectra control loop.
• Precision Compatibility: Direct-fit component for Series 94 electronic modulation systems utilizing dedicated mixing tubes.
• Rugged Construction: Built to withstand the high-velocity airflow and thermal cycling typical of industrial make-up air units.
• System Stability: Reduces temperature overshoot and hunting, prolonging the service life of Maxitrol gas valves.

Common Questions

Where should the TS194Q be positioned for optimal performance?
The sensor must be installed within the mixing tube to ensure the thermal element is exposed to a representative sample of the discharge air, avoiding dead spots or localized heat pockets.

How do I troubleshoot a suspected sensor failure in the Series 94 system?
Technicians should perform a resistance check across the thermistor leads and compare the readings against the Maxitrol TS194Q temperature-resistance curve to confirm the sensor is within calibration limits.

Can the TS194Q be used without a mixing tube?
It is highly recommended to use the specified mixing tube. Operating without one can cause turbulent airflow around the sensor probe, leading to erratic temperature readings and poor modulation control.
