KJT-SJ-I non-contact digital slip detector is an economical, reliable, simple and versatile monitoring device for shaft speed and other rotating devices. When it detects that the current speed signal is lower than or higher than In the normal speed range, the switch outputs a set of switching signals for alarm or shutdown. No moving parts, no wear, long safety life, integrated structure, centralized control device, simple setting or troubleshooting. The shell adopts a waterproof and dustproof design, and two bolts fix the shell, so it can be directly installed and used in harsh environments.
●The switch must be balanced and pressed on the fixed bracket of the rack;
●Tie the steel wire rope to the pull rings at both ends, and the rope on each side should not exceed 40m (it should be shortened when there is a slope);
●The pressure on the pull rope should be appropriate to ensure reliable reset of the switch;
●The drawstring is set parallel to the tape, and a lifting ring is added every 10m.
●The factory can purchase steel wire ropes according to the specifications required by users.
The address encoder uses a self-designed protocol to provide an RS485 communication interface to connect to the comprehensive protection instrument. By using shielded twisted pairs and communication repeaters, the transmission distance can reach 1km.
