di-soric ultrasonic sensors are used in automationing tasks for distance measurement and as proximity switches. They work on the principle of sound time measurement which ensures a reliable detection irrespective of colour or surface finish. Even transparent objects, liquids and powders are reliably detected. di-soric ultrasonic sensors are insensitive to dirt and can be applied on long distances. UItrasonic proximity switches, ultrasonic forks and ultrasonic though beam sensors without any blind zone round off the present range.
