RJJ5 fiber optic hot metal detector
The infrared radiation of the hot workpiece is collected by the glass lens of the hot metal detector and received by the optoelectronic device. If the energy exceeds the lowest set value of the optoelectronic device, the detector outputs a switching amount.
The RJJ5 hot metal detector is a split-type structure that transmits optical signals through optical fibers.
It can be tested at higher ambient temperature. The optical inspection head and optical fiber part can work normally in the environment of -25 °C ~ +500 °C. There are many models of optical detection head and controller.
Working voltage: DC24V or AC220V
Detection temperature: normal type: 550 ° C - 1400 ° C; low temperature type: 300 ° C - 1400 ° C
Output: level, relay, electrical contact
Response time: level, electrical contact: 2ms; relay: 20ms
