Siemens Building Technology 544-342-8 Temperature Sensor
The Siemens Building Technology 544-342-8 is a professional-grade duct averaging temperature sensor designed for precise climate monitoring in large-scale air handling units and complex ductwork. Featuring a 1k Ohm Platinum (375 alpha) RTD sensing element, this unit delivers high-accuracy resistance feedback to North American building automation systems. The primary advantage of this flexible averaging probe is its ability to mitigate the effects of temperature stratification by sampling air across its entire 8-foot probe length, ensuring the controller receives a representative average rather than a single-point reading that could be skewed by laminar flow or localized "hot spots."
Engineered for rugged mechanical environments, the Siemens 544-342-8 operates across a wide temperature range of -40°F to 180°F (-40°C to 82°C). The probe is constructed for flexibility, allowing technicians to snake the element across the duct cross-section using standard mounting clips. Connection is established via 20 AWG twisted pair leads within a standard NEC-approved junction box, facilitating seamless integration into existing HVAC control systems. This sensor is essential for discharge air, return air, or mixed air applications where precise thermal data is critical for staged heating and cooling efficiency.
Key Benefits- Sensing Accuracy: Utilizes a Pt1000 RTD element for stable, long-term duct temperature sensing without significant drift.
- Averaging Performance: The capillary-style 8-foot probe eliminates errors caused by air stratification in large commercial ducts.
- Wide Compatibility: Standard 1k Ohm output signal integrates directly with Siemens controls and most third-party BAS platforms.
- Durable Construction: Built to withstand the constant vibration and airflow typical of industrial air handling environments.
- Ease of Installation: Flexible probe design allows for custom grid layouts to maximize cross-sectional air sampling.
How should the averaging probe be oriented for maximum accuracy?
To get the most representative temperature, the 8-foot flexible element should be crisscrossed over the entire duct area. Ensure the probe is installed against the direction of airflow and maintained at least 50mm away from any heat exchangers or humidifiers.
Does this sensor require a specific controller?
The 544-342-8 is a passive RTD sensor. It requires a controller capable of reading a 1k Ohm Platinum (375 alpha) resistance curve to translate the signal into a temperature value.
What is the best way to secure the 8-foot probe within the duct?
Use specific Siemens mounting clips or copper strapping at every bend to prevent the probe from sagging or vibrating against the sheet metal, which can lead to mechanical failure over time.
