Resistance to environmental influences

 

Precipitation immunity

The interior parts of the instrument are IP67 waterproof. It is provided with a front screen extending above and in front of the apertures which protects it against direct precipitation. Typically, the instrument is angled downwards, which further protects the front apertures from precipitation.

Temperature range

The instrument is functional in the temperature range of -40°C to +60°C. Acceptable storage temperatures extend to +100°C.

Dirt build up on apertures

The front screen prevents against dirt falling down from above, and mounting the instrument at a sufficient height above the ground reduces the risk of splatter from passing vehicles. Reglular cleaning of the front apertures may be necessary.

Dew and frost

22W of heat is emitted primarily via convection from the cooling fins on top of the instrument. At use, this heats the instrument and prevents build up of dew or frost. When the instrument has been disconnected from its power source, frost or dew may remain on the front apertures for a short while after being powered on again.
