Siemens Building Technology 544-339-8 Sensor

The Siemens 544-339-8 is a professional-grade duct point temperature sensor engineered for precise thermal monitoring within commercial HVAC air distribution systems. This single-point sensor features high-performance 1k Ohm Platinum RTD (375 alpha) sensing technology, ensuring exceptionally accurate resistance feedback to building automation controllers. Equipped with a rigid 8-inch probe constructed from durable steel tubing, it provides robust penetration into the airflow for stable readings across a broad environmental range of -40°F to 180°F. Designed for seamless integration, the unit includes a standard NEC-approved 2x4 inch electrical conduit box with knockouts, simplifying field wiring for technicians and contractors. Whether used for supply air monitoring or return air tracking, this Siemens HVAC sensor delivers the industrial reliability required for sophisticated climate control logic.

• High-Accuracy Sensing: Utilizing a 1k Ohm Platinum RTD element for superior linearity and long-term stability in thermal detection.
• Industrial Durability: Features an 8-inch rigid probe designed to withstand high-velocity airflow without vibration or displacement.
• Standardized Installation: Integrated with a 2x4 electrical box for traditional mounting, ensuring compatibility with standard conduit systems.
• Broad Operating Range: Rated for temperatures between -40°F and 180°F, making it suitable for both cooling and heating applications.

Is the Siemens 544-339-8 compatible with non-Siemens controllers?

Yes, provided the controller is configured to accept a 1k Ohm Platinum (375 alpha) RTD signal. It is a standard passive resistance output used widely across multiple building automation platforms.

What is the primary application for this 8-inch rigid sensor?

This duct temperature sensor is typically used for single-point measurement in medium-sized ductwork where an averaging sensor is not required but high accuracy is essential for discharge or return air monitoring.

Can this sensor be used in liquid immersion applications?

No, this is specifically a duct point sensor. For liquid sensing in pipes or tanks, an immersion-style sensor with the appropriate thermowell must be used to ensure a pressure-tight seal and proper heat transfer.
