Description
The Siemens Building Technology 533-380-24 is a professional-grade duct temperature sensor engineered for reliable air temperature monitoring in commercial and industrial HVAC systems. Featuring a 4–20mA analog output signal, this sensor integrates seamlessly with building automation systems and DDC controllers, delivering accurate, continuous temperature data across the full duct airstream.
Key Features
- 4–20mA output signal for direct integration with BAS and DDC controllers
- Temperature sensing range: 20°F to 120°F (-7°C to 49°C)
- 24-foot flexible probe for thorough duct averaging and extended reach installations
- Lead-type connection for straightforward field wiring
- No display — clean, low-profile design suited for concealed duct mounting
- Flexible probe construction allows routing through bends and irregular duct geometries
Application
The 533-380-24 is ideal for supply air, return air, and mixed-air temperature sensing in air handling units, rooftop units, and large duct systems. The 24-foot flexible averaging element spans wide duct cross-sections to provide a representative mean air temperature reading, improving control accuracy and system efficiency.
