SWS-100 Present Weather Sensor

The SWS-100 is optimised for use in applications where accurate and reliable visibility measurements are required alongside basic present weather measurements. The forward scatter measurement principle and unique design ensure the output is both accurate and reliable in all weather conditions and will not be influenced by local light sources, even those that flash.

The availability of digital, analogue and switching relay outputs provides the flexibility to connect to a wide range of ITS (Intelligent Transport Systems), computer systems or local warning devices.

The unique ability to switch equipment using two fog relays and/or a precipitation relay is a feature of the SWS-100 sensor. For example; you can set the relays to automatically switch a speed reduction sign when the visibility is below 100 meters and then switch an additional ‘danger of aquaplaning’ alert when rains starts.

Full compliance with the visibility measurement requirements of the International Civil Aviation Organisation Runway Visual Range specification and easy integration of the Biral ALS-2 ambient light sensor makes the SWS-100 perfect for use in aviation applications where RVR data is needed.
