Description
The Siemens Building Technology 544-973 is a precision room temperature sensor engineered for building automation and HVAC control applications. Utilizing a Platinum RTD (Resistance Temperature Detector) sensing element with a 1,000 Ohm (1k Ohm) resistance at 0°C, this sensor delivers accurate, stable temperature feedback to building management systems and DDC controllers.
Key Features
- Sensing Technology: Platinum RTD (Pt RTD) — 1,000 Ohm (1k Ohm)
- Output Signal: 375a
- Temperature Range: 32°F to 122°F (0°C to 50°C)
- Connection Type: Leads
- Display: None
- Application: Indoor room/space temperature sensing
Application
Designed for wall-mount room temperature sensing in commercial and light industrial environments, the 544-973 integrates seamlessly with Siemens building automation systems and compatible third-party DDC controllers. The lead-wire connection simplifies field wiring, and the absence of a local display keeps the unit low-profile for clean architectural installations.
Why Choose the Siemens 544-973
Platinum RTD technology is renowned for its linearity, repeatability, and long-term stability — making this sensor a reliable choice for energy management, comfort control, and HVAC optimization in commercial buildings. The 1k Ohm element minimizes lead resistance errors, ensuring accurate readings across the full 32°F–122°F operating range.
