Detection in small openings

Ultrasonic sensors with a special sonic nozzle enable detection of objects and liquids in very small container openings, e.g. the filling of microtiter plates or test tubes.

Presence detection

Ultrasonic sensors detect objects regardless of their material, color or surface. Synchronization-or multiplex mode also enables reliable detection of large objects, gaps or even semi-transparent objects.

Object detection with stable signal thanks to filter function – Object detection in demanding environments

Object detection in demanding environments

Thanks to the rugged housing design and robust transducers, the ultrasonic sensors are also suitable for use in harsh conditions (e. e. washdown environment).

Technology

Ultrasonic sensors are based on the measured propagation time of the ultrasonic signal. They emit high-frequency sound waves which reflect on an object. The objects to be detected may be solid, liquid, granular or in powder form.  Ultrasonic sensors reliably detect transparent and other demanding objects where optical technologies fail.

Ultrasonic proximity switches – Functionality of ultrasonic sensors

Ultrasonic proximity switches

Transmitter and receiver are integrated in one housing. The sensor switches as soon as the sonic signal is reflected back by an object within the adjusted sensing range (background suppression principle).

Advantage: simple installation, low cabling efforts

Ultrasonic retro-reflective sensors

Ultrasonic retro-reflective sensors

Transmitter and receiver are integrated in the same housing. The sensor detects the sound reflected by a fixed reflector. The sensor switches as an object interrupts the distance between sensor and reflector.

Advantage: Independent of object attributes, reliable signal even with extremely weak or diffuse reflective or sound-absorbing objects

Ultrasonic through beam sensors

Ultrasonic through beam sensors

Transmitter and receiver are mounted opposite each other in two housings. The sensor switches as soon as an object interrupts the sound waves.

Advantage: shortest response times of all ultrasonic sensor principles, longer ranges than in the size comparable retro-reflective sensors or proximity switches
