Description
The Siemens Building Technology 535-490-18 is a precision duct temperature sensor engineered for commercial and industrial HVAC building automation applications. Delivering a linear 4-20mA output signal, it integrates seamlessly with building automation systems (BAS), DDC controllers, and energy management systems for accurate, real-time duct air temperature monitoring.
Key Features
- 4-20mA analog output signal for reliable, noise-resistant long-distance signal transmission
- Temperature sensing range: 20°F to 120°F (-7°C to 49°C) — ideal for supply and return air duct applications
- 18-inch rigid probe for secure insertion into ductwork of varying depths
- Lead wire connection type for straightforward field wiring
- No display — clean, low-profile design suited for concealed duct installations
- Compatible with Siemens APOGEE, TALON, and third-party DDC building automation platforms
Application
Designed for installation in supply air, return air, and mixed air ducts in commercial HVAC systems, the 535-490-18 provides the accurate temperature data needed for zone control, economizer operation, and energy optimization strategies. The rigid probe construction ensures stable sensor positioning even in high-velocity airstreams.
