water proof UV sensor with G3/4" thread for pantograph arc detection
Properties of Waterproof UV Sensor UV-Arc
The UV-Arc is a waterproof sensor with a male threaded body (G3/4") to be used on trains to measure intensity and length of pantograph arcs according to EN 50317. This indicates the quality of the contact between a pantograph and the contact wire and allow a location of defects at the wire within a rail network. The UV-Arc sensor is configured for this special application. It contains a very sensitive photodiode with an additional fi lter to suppress solar UVB sensitivity. The time constant is adjusted to the typical arc lengths and the metal housing provides high EMC safety.
