Belt Conveyor Monitoring

4B has a wide range of sensors for monitoring the various parts of your belt conveyor. The most common areas for monitoring include: bearing temperature, speed / motion, belt alignment and level / plug indication .

All of 4B's sensors can be connected to our hazard monitoring systems.

 

Bulldog - Conveyor Belt Misalignment & Rip Detection System

The Bulldog alignment and rip detection switch is an electro-mechanical system designed to detect dangerous misalignment of the conveyor and also detection of belt tear damage. The switch will detect horizontal misalignment of belts when contact is made with the roller, the roller arm will be forced to pivot by the belt activating a switch at 20º to trigger an alarm, and 35º to trigger a shut down procedure of the conveyor. The sensors are usually installed in pairs on opposite sides of the belt.

4b Touchswitch sensor

The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.

4B Pullswitch PST2000A

PVC coated steel pull wires and pigtails connect between the switches to provide easy installation and continuous emergency stop access along the length of the entire conveyor. Pullswitches can be installed at 60m intervals, reducing overall system cost. Quick location of a tripped switch is provided by a standard reflector or optional flag marker, and the tripped signal can be wired back to an indicator panel or PLC. The Pullswitch’s IP65 / NEMA 4, 4X, 9 rated enclosure is made from polycarbonate and stainless steel, making the housing corrosion resistant and weatherproof.

4B Binswitch

Detects level or plug situations for bulk granular solids or liquids in tanks, bins, or silos and can be used as a plug or choke detector in chutes, conveyors and elevator legs.

IE Node

The Industrial Ethernet Node (IE-NODE) is a remote monitoring interface designed to provide sensor data to PLC’s or other automation and control systems.

Both units can be expanded to 16 sensor inputs with the installation of optional expansion boards.

B400 Elite elevator / conveyor belt alignment monitor

The B400 Elite Beltswitch belt misalignment monitor uses 4B Touchswitch sensors to monitor belt alignment in bucket elevators and conveyors. Each control unit incorporates two independent monitoring circuits for early detection of belt misalignment on one or two bucket elevators / conveyors. The 4B Touchswitch is an electro-mechanical limit switch with no moving parts. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact.
