Sensors for measuring visibility and present weather

Wide range of visibility sensors designed for monitoring on roads and in tunnels. Models with a wide measuring range are available to detect fog and haze; models with both digital and analog outputs, as well as relays for activating external equipment to be integrated into intelligent transport systems and used to automatically switch warning signals in changing visibility conditions.

All models are also “Present weather” sensors, that is, they can measure the intensity of precipitation by providing the analysis of water particles: fog, rain, snow or mixed form.
