DESCRIPTION

Main uses and scope of application

In the process of conveying materials by belt conveyor, materials, sundries or metal parts may scratch or penetrate the conveyor belt, and the steel wire rope core conveyor belt may cause longitudinal tearing accident, which will bring great losses to your property and safety.

The longitudinal tearing monitoring device of conveyor belt is capsule type, which can reliably send out alarm signal and stop signal when the conveyor belt tearing accident occurs, to stop the continuous development of the accident in time. It is suitable for the safety protection of belt conveyor in various industries.

Working principle and performance

The capsule-type longitudinal tearing monitoring device consists of sensor and control circuit. The sensor is a detecting element for longitudinal tearing, When the conveyor belt is penetrated by foreign materials, the sensor is squeezed as the conveyor belt moves foreward, or when the sensor arranged at the discharge port is squeezed due to material blockage between the chute discharge port and the conveyor belt, the sensor can sensitively and reliably detect the tearing signal of the conveyor belt, output the switching value and send out the stop signal. The control circuit has delay function.

Power indicator lamp and alarm indicator lamp are the same lamp. After being electrified, it is always on as power indicator lamp and flashing as alarm indicator lamp.

After power-on, the indicator light is always on, indicating that the power supply is normal. Press the self-calibration button, and the indicator light flashes. At the same time, measure the output switching value conversion.

Then press the reset button, the indicator light is always on, and the output switching value is reset, indicating that the control box is normal.

The device has the following characteristics

(1) Convenient installation;

(2) The sensor of the detection element has strong sealing performance and can be used under harsh conditions;

(3) The panel of the control box is provided with a self-calibration button. When the self-calibration button is pressed, the field fault can be simulated and the tearing alarm function mentioned above can be realized.

Special control alarm instrument

 

Special control alarm instrument

 

Semiconductor planar light-emitting device, with high brightness, soft color, low power consumption, parallelly driven and long working life.

It can communicate bidirectionally with various detection and control instruments, PLC DO point, PLC serial port, touch screen, industrial personal computer and other equipment with communication interface, and form a monitoring system, using standard ModBUS-RTU communication protocol (international common).

It is designed according to international standard procedures; can also be made according to user requirements; and has alarm memory function.

There are buzzer, test and silencing buttons inside the instrument, and there are external buzzer interface (passive contact signal) and test and silencing button interface.

The instrument has clamp-in structure design and is compatible with demestice XXS series flash signal alarm, which is convenient for installation, maintenance and replacement.

Instrument power supply AC220V.
