Description
The Siemens Building Technology 540-244-18 is a precision duct-mount temperature sensor engineered for reliable air temperature monitoring in commercial HVAC and building automation systems. Featuring a 100k Ohm thermistor output signal, this sensor delivers accurate, low-drift readings that integrate seamlessly with building management systems (BMS) and direct digital control (DDC) platforms.
Key Features
- 100k Ohm thermistor output signal for accurate, stable temperature measurement
- Wide sensing range: -40°F to 180°F (-40°C to 82°C)
- 18-inch rigid probe for secure duct insertion and consistent airstream contact
- Lead wire connection type for straightforward field wiring
- No display — designed for clean, low-profile installation in duct applications
- Compatible with Siemens Building Technology BMS and DDC controllers
Application
Ideal for monitoring supply air, return air, and mixed air temperatures in air handling units (AHUs), rooftop units (RTUs), and duct distribution systems. The rigid 18-inch probe ensures the sensing element reaches the center of the airstream for representative temperature readings, while the thermistor output provides a high-resolution signal suitable for energy management and comfort control strategies.
