Area Mass Sensors

Smooth, precise, self-correcting speed control of mass conveyors

Sencon's AMS sensors monitor cup accumulation on the cupping press discharge or distribution conveyor. The AMS analog output regulates the variable speed drive of the cupping press, adjusting the rate of press strokes based on cup demand. AMS sensors are also used control pressure on canline conveyors, providing an analog signal that is proportional to can density/can back-up on the conveyor. The signal is used to modulate machine speed or conveyor speed accordingly.

Unique sensors that revolutionized conveyor control on canmaking lines

Sencon's AMS sensors provide an analog signal that is proportional to can density/can back - up on the conveyor. The signal is used to modulate machine speed or conveyor speed accordingly.

STABLE CONVEYOR CONDITIONS

Conveyor stability is vital for today’s lightweight cans and high speed machinery. The AMS enables complete control, creating optimum conveyor conditions and accumulation space as well as minimum can pressure.

CONVEYOR PRESSURE CONTROL

This is accomplished by varying conveyor speed relative to fill level. When full, the conveyor should run at machine rate, creating no excess can pressure. However, as the conveyor empties, the speed should increase. Thus, when recovering from an empty-out situation, conveyor speed is at a maximum, reducing transit and refill times and adding precious seconds into line efficiency.

CUPPING PRESS MODULATION

The AMS is frequently used to monitor cup accumulation on the cupping press discharge or distribution conveyor. The AMS analog output is used to regulate the variable speed drive of the cupping press, adjusting the rate of press strokes based on cup demand.

Area Mass Sensor – how it works

HOW THE SYSTEM WORKS

These systems work on Sencon’s proven capacitance sensing principles and use an array of coated stainless steel wires or a wire mesh as the sensing element. This may be suspended over the conveyor in a canopy fashion, constructing a sensing window the size of the sensing element area. The output signal is proportional to the number of cans within the sensing window. The sensing array is connected to a transmitter (T400WR-UC) which converts the sensor signal to a control signal — either analog or digital.
