Meet the Sensors

With a complete range of sensors for temperature, humidity, air quality, and pressure, Belimo can serve as
your single-source provider of HVAC field-level devices for any building project.


Outdoor air, duct, and pipe temperature sensors are designed for easy installation and are compatible with all major BAS.  Up to eight active measurement ranges simplifies field selection and reduces stock storage for maximum flexibility. Output signals include passive NTC, RTD, 0 5/10 VDC, or 4 to 20 mA.


Durable duct, outdoor air, and condensation sensors are manufactured using the highest quality materialsCombined temperature and humidity sensors provide a flexible and cost-effective solution.  Multi-sensor with selectable output measurement values: relative humidity, absolute humidity, enthalpy, and dew point. 

BACnet or Modbus RTU is available on select models.

Air Quality

Belimo offers a wide range of combined multi-sensors for CO2, humidity, temperature, and VOCs designed to ensure air quality.  Dual Channel self-calibration technology enables the Belimo CO2 sensors to be used for all types of buildings and applications where ABC logic can not be used.

BACnet is available on select models.


Pressure sensors from Belimo can measure extremely high and low pressures in both air and water applications. They offer precise measurement of pressure, differential pressure, and velocity for reliable monitoring. 

Selectable measuring ranges are available for application flexibility.

 Modbus RTU is available on select models. 

Reliable Quality and Seamless Integration 

with Belimo's Sensor Line

The Belimo Quality You Trust 

Belimo, the global leader in the development, production, and marketing of actuators and control valves, added a line of sensors to its product range. Belimo sensors offer trusted reliability, easy installation, and seamless integration with major Building Automation Systems (BAS). They offer a complete line of sensors for measuring temperature, humidity, pressure, flow, C02, and volatile organic compounds (VOCs) in pipes, ducts, and outdoor applications.

Belimo sensors feature innovative uniform enclosures, which allow for easy installation and commissioning. The universal enclosure design streamlines the entire product range and complements Belimo's existing line of actuators and valves.
