Explosion-proof Run-off Switch

It is used for the detection of the runout of conveyor tapes to prevent faults such as material overflow due to tape runout. This machine is widely used in the transport systems of mining, power and chemical industries.

Working principle:

When the running tape is deflected, the tape edge with support rotation andsqueeze the stick to make it tilt, if the stick tilt is greater than thefirst actionangle, a set of switch signals will be issued immediately, if the stick continuesto tilt greater than the second action angle, another set of switch signals willbe output, two sets of switch signals can be used for alarm or stop, the tapemachine back to normal operation, the stick automatically reset.


Installation and use:

1. Fix the runout switch on the bracket and weld it to the tape frame.

2. The axis of the vertical stick is perpendicular to the tape plane, and thedistance between the vertical stick and the edge of the tape is L=50 100mm.

3. The tape is positioned at the lower 1/3 of the end of the stand.

4.A pair of runout switches can be installed for every 50M of tape.
