• Supported languages DE, EN, FR, IT, ES, PT

Configuration options
• Individual configuration of output signals
• Setting of different measuring ranges
• Additional adjustment of offset values
• Parameterization of Live-Zero-Signal (2..10 V etc.) and the system of units
• Setting options for display indications
• Customized parameterization of traffic-light function (TLF)
• Extension of the physical Modbus address
• Store settings on the mobile device and load on other sensors
• Representation and output of the differential pressure as a volume flow value

Available in North America, European Union, EFTA States and UK.

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.
