TACHOMETRIC ROLLER

for belt conveyors

Tachometric roller for belt conveyors in many sectors

The tachometric roller is a monitoring roller for conveyor belt protection. The speed sensor inside this type of product is installed in place of a lifter. The tachometric roller is supplied with a ring for length adjustment. Speed information is transmitted as a variable-frequency electrical pulse.

Conveyor belts are used in many sectors, such as the food industry, mining and many others. The tachometric roller is an indispensable device for monitoring and protecting this essential equipment.

Operation and use of the tachometric roller

The tachometric roller is a mechanical device that measures the speed of rotation of an axis. It generally consists of a toothed wheel fixed to the roller axle and a sensor, usually inductive, which detects and measures the passage of the wheel’s teeth. By counting the number of passes in a given time, it is possible to determine the speed of rotation of the roller and, consequently, the speed of the conveyor belt. This rotation is then analyzed by measuring instruments, which translate the data into a precise distance or speed. So it’s constantly on the move.

This constantly rotating mechanical component rotates at a speed proportional to that of the object or mechanism being measured. Each time the roller turns, a series of pulses is generated. The tachometric, meanwhile, counts these pulses over a given period, enabling the speed of the object concerned to be deduced.

This type of product is guaranteed precision and durability. Its ability to withstand various stresses (such as temperature or wear) has a direct influence on the tachometer’s reliability.

Web speed monitoring

Conveyor belt speed control is crucial to ensuring the quality of the products conveyed and preventing operating problems. Conveyor belt speed control is crucial to ensuring the quality of the products conveyed and preventing operating problems. By monitoring speed via the tachometric roller, speed can be adjusted to maintain optimum performance and prevent problems.

Protection against overloads and unexpected shutdowns

Another advantage of tachometric roller products is that they can detect overloads and unexpected stops of the moving conveyor belt. In the event of overload, roller speed may decrease, signalling a potential problem. Similarly, if the speed suddenly drops to zero, this indicates an unexpected stop, which may be caused by a belt jam or break. In these situations, the control system can react quickly by stopping the belt or adjusting its load to avoid damage.
