"What is the concentration of the detergent in the bath?“
"Does my bathroom still clean the next five heavily soiled components?"
"What is the protein's percentage in the milk?"
"Is my cow healthy? Is she fed optimally?"
"Does the delivered liquid include unwanted additives?"
"I can document the composition of my liquid product across the whole process line without any sample-taking."
|"Is it possible to detect a carryover, e.g., by a cooling lubricant, into subsequent process steps and identify the source?"|
In contrast to conventional electrical methods of characterisation, the impedance spectroscopy applies an AC signal to the material under test for a wide range of frequencies.
This method offers non-invasive, in-line measurements in real time. The harmless, emitted electromagnetic wave interacts with the material and can be measured.
The advantage of ultra wideband impedance spectrocopy over other technologies lies in the wide frequency range that is covered: it allows to detect different constituents of a complex liquid mixture in a single measurement.
|MINIATURISATION: compact and robust sensors|
|NON-INVASIVE: no direct contact to the medium necessary|
|REAL-TIME: up to 100.000 measurements per second|
|ULTRA WIDEBAND: measuring the composition of a (complex) liquid|
|PSEUDO-NOISE SIGNALS: harmless and hard to disturb|
