Scanning head HD1080

Scanning head HD1080

Each measurement position of a stationary test system can be equipped with a scanning head HD1080 mounted on a fixing device for easy positioning in all 3 axes. All scanning heads are additional mounted on a common rail and have facilities to lift away from the meter in case of meter change.


The scanning head HD1080 is developed to scan rotor marks and LED’s of electronic meters. It can be used to scan Infrared diodes as well. If the HD1080 is used to scan rotor marks of Ferraris meters, two pulsed LED’s light up the rotor disk. The reflected light is pulsed as well and can be detected independent of the background light.
