Scanning Head

A wired scanning head belongs to the standard scope of delivery for the RS350. It can detect rotor marks for electromechanical meters and pulse diodes for electronic meters. LEDs with a wave-length of 400 – 1100 nm and with pulse frequencies up to 3 kHz can be detected.
The scanning head is delivered with a fixing device. The clamping width is 10 mm to 180 mm.
