Sensors
Energy-efficient, innovative measurement that pays off over the long term

High quality and comprehensive portfolio
Saving energy thanks to highly accurate measurements – Siemens sensors record and transmit readings extremely quickly and accurately, providing an optimal basis for precise and therefore energy- and cost-efficient control of the entire HVAC plant.
With innovations such as integrated self-monitoring and highly versatile multisensors for different applications, Siemens sensors are a secure investment for the future. And thanks to a simple installation concept they can be quickly installed and put into operation – so your investment pays off right from the start.

A range of sensors to meet every need
Whether for measuring temperature, pressure, humidity, air quality or flow in rooms, ducts or outside areas, Siemens offers a transparent, clearly structured range of sensors for typical HVAC measurements and applications. The range also includes multisensors that measure mixed gases, as well as sensors for special areas.

Digital correction algorithms guarantee clean, clear measurement signals. Tested applications ensure full compatibility with all HVAC controllers from Siemens. In addition, the connection to standard commercial third-party systems is always an option thanks to standardized output signals.

Highlights:
  • Perceptible energy savings – thanks to fast, high-precision measurement and efficient measuring techniques"
