Airbus uses Balluff sensors in A380 restrooms

Balluff product story

Airbus is equipping the restrooms in its four-engine large-body A380 with a titanium mixer tap using Balluff's Smartlevel technology.
At the heart of this system in the Airbus design are compact, capacitive sensors from Balluff using Smartlevel technology.
The tap design allows passengers to select water temperature and flow supported by a digital light-emitting-diode (LED) feedback display, saving water and waste.
Possible false triggers by the sensors are eliminated because Balluff's contactless capacitive sensors compensate automatically for residues, such as the material build-up of soap and liquid on the sensing surface.
Even a wet paper towel placed onto the sensing areas will not lead to false activation of the sensors, according to the company.
The switching precision is made possible by Balluff's patented oscillation technology, which allows the sensor to suppress undesired interferences.
The company claims that, in general, level-detection applications of heavily foaming liquids or those that leave a film residue are a difficult task for standard capacitive sensors.
Thicker container walls require time-consuming setup procedures.
The material build-up of adhesive media on the inside of the container walls causes the sensors to repeatedly indicate an inaccurate liquid level.
The new self-adjusting capacitive sensors are intended to overcome these problems.
