Sonar loop speed control with ultra-sonic sensing

Minimum stretch speed control for flexible extrusions

Our sonar loop control unit uses an ultra-sonic sensor to monitor the position of flexible extrusions between two points.

It is typically used to automatically control the speed of a motorised pay-off unit or syncronize speeds between two belt puller belt units in-line.

The main advantage of the sonar loop is that it gives a controlled speed signal while ensuring the extrusion is not stretched. This is often vital when handling more flexible materials such as silicone, rubber & certain flexible plastics. The sonar loop usually gives a significant improvement to cut length control & accuracy.

The sonar head is fixed in a robust floor-stand. The sensing range is controllable, with an analog 0-10V speeed control output relative to the position of the extrusion in the loop. The unit is finished to IP67 protection & operates on a low voltage 24VDC supply.
