Siemens Building Technology 544-342-24 Temperature Sensor

Engineered for high-precision building automation, the Siemens 544-342-24 duct temperature sensor is a critical component for large-scale air handling systems where temperature stratification is a concern. This flexible averaging sensor features a robust 24-foot probe length, allowing for comprehensive data collection across the entire cross-section of a duct to ensure accurate thermal reporting to the controller. Utilizing a 1k Ohm Platinum RTD (resistance temperature detector) with a 375-alpha coefficient, this unit provides exceptional linearity and stability in demanding HVAC environments. The 544-342-24 is designed for seamless integration with legacy Siemens Apogee and modern Desigo building management systems, transmitting a precise resistance signal via standard leads.

• Enhanced Thermal Accuracy: The 24-foot averaging temperature probe mitigates errors caused by air stratification, providing a true average temperature for better fan and coil control.
• Industrial Durability: Housed in a standard 2x4 inch junction box, the Siemens RTD sensor is built to withstand rigorous mechanical room conditions.
• Broad Operating Range: Accurate HVAC duct temperature monitoring from -40°F to 180°F (-40°C to 82°C), suitable for both supply and return air applications.
• Building System Compatibility: Native support for systems requiring 1000 Ohm Platinum RTD inputs, ensuring straightforward field replacement and calibration.

Common Questions

Is the 544-342-24 compatible with non-Siemens controllers?
Yes, as long as the third-party building automation system or PLC is configured to accept a 1k Ohm Platinum RTD (375 alpha) signal, this duct averaging sensor will function as intended.

What mounting hardware is required for the 24-foot probe?
For proper installation, the probe should be supported across the duct using mounting clips or a capillary bracket kit to prevent sagging and ensure even coverage of the airflow path.

Can the probe be trimmed to a shorter length?
No, the Siemens 544-342-24 probe length is factory-set. Altering the physical length of the flexible element will damage the sensing circuit and invalidate the 1000 Ohm resistance calibration.
