optoelectronic sensorelement for reliable detection
of aqueous precipitation, for use in traffic engineering to save
energy in heating switch points, bridges and streets

Reliable detection of all aqueous precipitation 1 switching contact "heating on" Serial interface, galvanically insulated 1 input rail temperature (4...20 mA) Quadruple analogue output optionally for air temperature, relative air, intensity of precipitation and air pressure Intelligent self adjustment in case of soiling Internal heating effective down to -30°C Optional mounting device, galvanized Optional display in cover of case

mit kapazitivem Messelement, zur Ermitlung der relativen
Luftfeuchtigkeit, optional der Temperatur

Measurering range for humidity 0...100% relative humudity Measuring range for temperature 0...+40°C; 0...+50°C -10...+90°C; -30...+60°C or 0...+100°C Operating range for humidity +10...+95% relative humidity Operating range for temperature -30...+80°C Measuring medium unpressurized,non aggressive and non condensing air Output 0...20mA or 0...10V (3-/4-wire) or 4...20mA (2-wire) Supply voltage 15...30VDC or 24VAC Accuracy +/- 3,5% relative humidity accuracy temperature +/- 0,8°K
