Your benefit

Process stability in aggressive environments
- Unaffected by moisture and vapors
- Chemically resistant to aggressive media thanks to a patented parylene sensor front and a completely metal housing with no weak points (LEDs)
- Pressure-resistant up to 6 bar
- Sensor consists of FDA-compliant materials for use in the F&B industry
Reliable and efficient object detection
- Minimal interfering reflections thanks to extremely narrow sonic beams (+/- 10 mm)
- M18 versions with a wider sonic beam allow larger sensing distances
- Thanks to response times < 6 ms, the sensors are ideal for fast applications
- Sensing distances of a maximum of 200 mm (M12) or 1000 mm (M18)
- Retro-reflective sensors guarantee absolutely reliable object recognition (beam interruption principle)
Simple, cost-effective installation and setup
- Housing in industry standard stainless steel M12 and M18
- Extremely simple installation due to the elimination of vibration-free mounting required with typical ultrasonic sensors

Applications

Presence detection of bottles in fast star fillers to prevent filling failures
Presence detection in aseptic filling machines
Level detection in pressure tanks up to 6 bar
Level measurement in lab technology (e. g. ink)

Technology

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

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
