Tension Loop Control for Clear Plastic
In this application, monitoring of the tension loop control is done by an ultrasonic sensor, the Banner S18U. The S18U bounces sound waves off of the clear plastic for a reliable and consistent sensing application. Standard photoelectric sensors have difficultly detecting clear material, particularly if its condition changes – in this application, the loop will fluctuate.As the loop fluctuates, its distance from the S18U also changes.
