Pepperl+Fuchs developed the ultrasonic sensor series UC18GS with view to both current and future application requirements. Thanks to the adjustable sound beam width and the particularly small dead band of 30 mm at 500 mm range or 70 mm at 1000 mm range, smooth operation is possible without loss of range—even in challenging environments or confined spaces. If, for example, steps on the interior wall of the tank or machine parts protrude into the detection range, the sound beam of the sensor can be configured correspondingly narrower. An integrated interference target suppression provides double protection against any false echoes and ensures reliable measurement results at all times. The UC18GS ultrasonic sensors not only adapt optimally to the application but also increase process reliability at the same time. Target distances, such as liquid levels, can be precisely measured even in the suppressed range without the need for costly adjustments to the application.

The automatic synchronization also enables the parallel and trouble-free use of up to ten sensors in a confined space—without any parameterization effort. For this purpose, each ultrasonic sensor of the UC18GS series has a synchronization input. To suppress mutual interference („crosstalk“), the respective synchronization inputs are interconnected and ultrasonic pulses are emitted in a self-multiplexing, common or externally-triggered mode.
