Exercises Exercise 4.1 Application of an inductive proximity sensor
The number, distance and direction of transport of material containers are to be
checked on a conveyor belt. For the purpose of marking, the transport containers are
provided with an aluminium marking plate. What do you need to consider when
selecting an inductive proximity sensor for this task?
How do you achieve the largest possible switching distance for a given sensor
What do you need to pay particular attention to in this instance?
What is the positive influence of the hysteresis on the switching behaviour of an
inductive proximity sensor? Consider what you would need to observe in practice if
switch-on and switch-off point were exactly the same distance from the proximity
sensor. 58 © Festo Didactic GmbH & Co. KG • FP 1110 4. Inductive proximity sensors Exercise 4.2 Detection of vibrating steel cylinders
Steel cylinders are transported on a conveyor belt, see fig....
