Belt tear detector is a protective device to detect and alarm the longitudinal tear of conveyor belt. It is used for automatic alarm or emergency stop when the conveyor belt is torn, punctured, damaged at the junction or sharp objects protruding out of the conveyor belt.

Features:

1.Trigger within 90 degrees range, full protection

2.Action stroke is less than 5 codes, detection blind area is as small as 1cm

3.Self-detection function, which can be replaced in time when it is accidentally damaged

Why is there a tear?

When mining raw materials such as ore and coal, sharp iron and wood are mixed in due to various reasons, such as tool loss, on-site repair, etc., which enter the chute with the raw materials, fall and run through the belt.

According to statistics, 99% of conveyor belt tearing faults occur at transfer points, which are specifically in the following two situations：

-The penetrating foreign objects moves forward with the belt, touches the idler, and splits the conveyor belt.

-If it can't be found in time, the whole belt will be split, resulting in production stagnation and major economic losses.

Detection principle

When an extraneous matter or a large piece of material pierces or a sudden abnormal sag of the conveyor belt, the     extraneous matter will squeeze with the sensor installed in front of the roller, thereby triggering the belt detection         sensor. The detector receives the sensor signal and converts it into a switch signal output ( Stop signal), so as to prevent the conveyor belt from tearing or within the minimum range.

The penetrating foreign material moves forward with the belt and touches the sensor detector.

The sensor detector sends the signal to the converter, and the converter sends out the switch signal of shutdown and alarm.

The conveyor power system loses power and stops running.

Features and advantages

-It can be triggered within 90 degrees to protect in all directions；

-The movement stroke is less than 5mm,and the detection blind area is as small as 1cm；

-Self-detection function, it can be replaced in time when it is accidentally damaged；

-Fault indication function, which is convenient for users to quickly find fault points；

-Delay function, can solve the malfunction interference；

-EPDM Cover，  longer service life；

-Customized frame, better fit with the conveyor belt

​

-When the detector is touched by a foreign object, the converter will send a signal.  ( 1NO+1NC)。

-Stable, and the reaction time (0~9 seconds) can be adjusted as needed to avoid misoperation.。

-The sensitivity adjustment can be adjusted according to the requirements to meet the requirements of different working conditions.

-Self-detection alarm function, protect the safety of the conveyor belt comprehensively. When the sensor is damaged and the line is faulty, a fault alarm signal is sent out.

-After triggering, the fault must be cleared before resetting, so as to avoid belt damage caused by forced startup.

-After troubleshooting, the operator needs to reset it manually before running, so as to ensure the life safety of the maintenance personnel of the conveyor.

-A single controller can be equipped with up to five sensors, which can cover the whole blanking point. Each sensor has an independent channel, and has the function of indicating the fault point, thus reducing the troubleshooting time and downtime.

-The detector is 10~ 15mm away from the idler, which can reduce the detection blind area.

-After installation, adjust the height of the sensor by using the height adjustment hole on the detector.

-The sensor should be 30mm away from the belt surface. This distance can accurately catch the foreign bodies passing through the belt, and avoid the accidental touch caused by the vibration of the belt.
