Two stage deviation switch KPT1-20-3S parameter 380V 3A is also called anti deviation switch. It is used to detect the deviation of belt conveyor during operation, and output alarm or shutdown signal according to the actual deviation of belt, which can effectively prevent accidents caused by belt deviation. The deviation switch of this series has two-level action function. The first level action is used for alarm, and the second level action is used for automatic shutdown. During the operation of the belt conveyor, when the belt deviates and contacts the vertical roller of this switch, the vertical roller rotates automatically. If the deviation continues to increase, the vertical roller of the extrusion will shift.
The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, automatic adjustment of running deviation can be realized without stopping the machine.
The secondary switch signal is used to stop the machine. Connect this signal to the control circuit to realize automatic stop under heavy deviation.
After troubleshooting, the vertical roll can be reset automatically when the tape leaves the vertical roll for normal operation.
In order to adapt to long-term use in outdoor conditions, the product is sealed as a whole, and the internal metal parts are galvanized and purified. The external parts, except the shell, are multi-layer bright chrome plated. The shell is made of cast aluminum/stainless steel, and the surface is treated with electrostatic spraying technology, which is suitable for use in harsh environments.
Operating principle of deviation switch
When the running tape deviates, the edge of the tape drives the vertical bar to rotate and extrude to make it tilt. If the vertical bar tilt angle is greater than the first level action angle, the switch sends out a group of switch signals. If the vertical bar continues to tilt more than the second level action angle, another group of switch signals will be output. The two groups of switch signals can be used for alarm or shutdown respectively. After the belt conveyor resets and operates normally, the vertical bar resets automatically.
Imported travel switch is adopted, with large contact capacity, sensitive action and long service life.

The two-level deviation switch consists of a hard contact and an address coding circuit. The two microswitches are used for the first level deviation alarm hard contact and the second level deviation alarm hard contact, respectively, for the conveyor deviation alarm and emergency stop. When the address coding two-level deviation switch acts, the address coding circuit will immediately send alarm information and address code through the communication loop. The micro switch is used as the hard contact inside the address coding two-level deviation switch, which is safe and reliable. When the address coding two-level deviation switch loses power supply, the address coding two-level deviation switch can have the function of a common protection switch, without affecting the safety protection function.
