Reliable as expected

Outdoor sensors from Belimo for measuring outside temperature and humidity for efficient heating and cooling automation.

Innovation for peace of mind

Precise measurement outdoors

Belimo sensors for mounting outside buildings are equipped with an IP65 housing, a snap-on cover and a mounting plate. They are available with passive or active outputs and are compatible with all common building automation systems. 

Combined temperature and humidity sensors with selectable outputs for relative humidity, absolute humidity, dew point and enthalpy are optionally available with BACnet and Modbus communication. 

All outdoor sensors are UL-certified and come with a 5-year guarantee.

Product range

Customer-specific products

These days, challenges in planning and on the construction site are difficult to solve using standard products, which is why customer-specific solutions are becoming increasingly important. We build the sensor you need – with the cable length, connector plug and parametrisation you specify. On request, we mount the sensor to a valve and create a pre-mounted assembly from pipe parts, connections and much more.

  • Different cable types and lengths with or without a connector plug. 
  • Product labelling with your customer information (e.g. where the actuator is to be installed in the building). 
  • Various mounting options (adapted to your installation situation on-site). 
  • Wide range of electrical and mechanical accessories. 
  • We take care of the parametrisation for you (e.g. adjustable running time, switching differential and bus parameters).
  • Completely prefabricated and tested assembly (e.g. seal integrity) with components of your choice.
  • Function test, because Belimo stands for tested quality.

We offer a "complete carefree package" for your application.
