-> This is a new optical fiber type CMD using LED as light source. This equipment is composed of transmitter(Sensor head, heat-resistance fiber and amplifier) and receiver and detects steel material which passes through between them.
-> This doesn't specify power source. It is capable of being used within the scope of 100 to 240VAC.
-> Water-cooling or air-purge isn't required for sensor head because non-air dust purge hood is applied.
-> 8-point LED display unable to monitor the margin and emitting state.
-> Warning output is provided.
