LJJ1 cold metal detector
When the measured object blocks the output of the light source output from the detector.
The cold metal detector (LJJ series) is mainly used in metallurgical systems to enable on-line inspection of on-site (opaque) objects.
Cold metal detectors can be divided into two categories: red light type and infrared light type according to different light sources.
According to different detection methods, it can be divided into three types: on-beam, reflective and self-reflective.
Working voltage: AC24V or 220V
Detection distance: red light 12m, infrared light 25m
Minimum detection distance: Φ20mm
Working environment: -25℃ ~ 65℃, after adding water to 130℃
Response time: relay 20ms, level, electrical contact 2ms
