Ultrasonic sensors may be a useful alternative where optical sensors come up against their physical limits. This applies, for example, for objects with uneven surfaces or under difficult ambient
conditions, or with highly transparent media as well as moving,
highly reflective liquid surfaces. Typical uses of ultrasonic sensors
are therefore checking the presence of highly transparent foils
and measuring the filling levels in liquid containers. A major advantage of ultrasonic sensors is the absolutely reliable background suppression resulting from their sound time-of-flight
measurement principle.

The new ultrasonic sensor with soundpipe (UT 20 ), in its very
S
compact cubic housing, is a special product variant. As a result of
its narrow sound cone, it allows the detection of objects even
through the smallest of openings and drilled holes with a diameter of less than 5 mm. This makes it ideal for special applications,
such as level measurement in the wells of microplates in medical
analysis systems or for scanning circuit boards in the electronics
industry.
The ultrasonic sensors of the UMT 30 series are real multifunctional artists. A three-digit display makes all sensor settings easy
for users. The add-on menu with numerous supplementary functions, e.g. the synchronisation of several sensors or multiplex operation, in which several sensors measure after one another in ascending order, allows the UMT 30 to offer extremely flexible use
for a wide range of applications.
