Siemens Building Technology 533-380-24 Temperature Sensor

Siemens Building Technology 533-380-24 Temperature Sensor

The Siemens 533-380-24 is a professional-grade duct averaging temperature sensor designed for precise climate monitoring in commercial HVAC systems. This unit features a 24-foot flexible probe, making it the standard choice for large air handling units (AHUs) where air stratification often leads to inaccurate readings from single-point sensors. Utilizing a 100 Ohm Platinum RTD (Pt100) sensing element, the 533-380-24 provides a reliable 4-20mA output signal, ensuring seamless integration with most Building Automation Systems (BAS) and North American controllers.

This sensor is built for durability in demanding environments, housed in a rugged 2x4-inch metallic junction box with 1/2-inch knockouts for standard electrical connections. The flexible capillary allows for comprehensive coverage across the duct cross-section, capturing a true average temperature between 20°F and 120°F (-7°C to 49°C). For technicians managing complex air distribution, this 4-20mA duct sensor offers high measurement accuracy of ±0.54°F at 32°F, mitigating the risk of short-cycling and improving overall system efficiency. The lead-based connection type and lack of local display focus entirely on remote monitoring reliability.

Key Benefits for HVAC Contractors:
  • Mitigates Air Stratification: The 24-foot length ensures accurate average readings in high-volume ducts where temperature layers exist.
  • Industry-Standard Output: Features a 4-20mA analog signal for long-distance transmission without signal degradation.
  • Robust Construction: Equipped with a galvanized steel or metallic enclosure rated for NEMA 1 protection in mechanical rooms.
  • Universal Compatibility: Works with a wide range of Siemens components and third-party PLC/BAS hardware.
  • Simplified Installation: Standard utility box design and flexible element allow for rapid mounting with standard clips and no specialized tools.
Common Questions & Technical Insights:

How do I handle the excess capillary length during installation?
If the 24-foot probe exceeds the duct width, the capillary should be neatly coiled and secured using spacing clips. Avoid sharp bends (minimum radius 50mm) to prevent damaging the sensing element.

What is the power requirement for the 4-20mA loop?
This sensor typically operates on a 24V DC loop power supply. Always verify the voltage drop across the entire circuit to ensure the transmitter has sufficient overhead at 20mA.

Can this be used for outdoor air intake monitoring?
While the probe can handle the temperature range, the junction box is rated for interior NEMA 1 environments. For outdoor applications, ensure the housing is protected from direct moisture and solar radiation.
