Ultrasonic Technology
Ultrasonic proximity sensors can be used as a non-contact device in many areas of automation.
They are employed wherever distances have to be measured in the air, since they not only detect objects, but they can also
indicate and evaluate the absolute distance between themselves and the target. Changing atmospheric conditions such
as temperature are compensated during evaluation of measurement. Ultrasonic proximity switches working as diffuse or
reflex sensors send out ultrasonic impulses in cyclical intervals. If these are reflected by an object, the resulting
echo is received and converted into an electrical signal. TARGETS Ultrasonics Ignore
