Siemens Building Technology 544-342-16 Temperature Sensor
The Siemens 544-342-16 is a professional-grade flexible averaging duct temperature sensor designed for accurate thermal monitoring in large-scale HVAC air handlers and supply ducts. Engineered with a 16-foot flexible probe, this sensor mitigates the effects of temperature stratification by providing a true average reading across the entire duct cross-section. Utilizing a high-precision 1k Ohm Platinum RTD (375 alpha) sensing element, it delivers a stable resistance output signal compatible with most major building automation systems (BAS) and Siemens industrial controllers. The probe’s bendable design allows for custom serpentine installation patterns, ensuring comprehensive coverage even in complex duct geometries. With an operating range of -40°F to 180°F (-40°C to 82°C), this duct temperature sensor is built for the rigors of commercial air distribution. The unit is housed in a standard NEC-approved 2x4 inch utility box with 1/2-inch knockouts, facilitating rapid integration into existing control loops without specialized mounting hardware.
- Stratification Compensation: The 16-foot flexible averaging probe ensures high-accuracy readings in large ducts where air temperature is inconsistent.
- Platinum RTD Precision: Features a 1k Ohm Pt RTD element (375a) to provide long-term stability and minimal signal drift.
- Universal BAS Compatibility: Industry-standard output allows for seamless integration with Siemens, Talon, and other North American building controls.
- Durable Construction: Designed for an environmental operating range of -40 to 180 degrees Fahrenheit for high-demand HVACR applications.
- Simplified Installation: Standard lead-type connections and a bracket-mounted design streamline field replacement and commissioning.
Common Questions
What is the advantage of an averaging sensor over a single-point sensor?
In large air handlers, air can separate into layers of different temperatures. A single-point sensor only reads one spot, whereas the 16-foot averaging duct sensor measures the temperature along the entire length of the probe, providing a more accurate representation of the total airflow temperature to the controller.
Is the probe flexible enough for a serpentine install?
Yes, the 544-342-16 features a flexible, bendable probe specifically designed to be zigzagged across the face of a coil or duct to capture the highest possible sampling area for the BAS.
What control systems are compatible with the 1k Ohm Platinum RTD?
The 1000 Ohm Platinum RTD with a 375 coefficient is a standard signal type used by Siemens Building Technologies and is also natively supported by many third-party HVAC controllers and generic resistance-to-analog inputs.
