"What is the concentration of detergent in the bath?"
"Is the cleaning fluid sufficient to clean the next five extremely contaminated parts?"
"What is the milk’s protein percentage?"
"Is my cow healthy? Is it being fed optimally?"
"Does the delivered liquid contain unwanted additives?"
"I can document my liquid product’s composition throughout the entire process line without taking any samples."
|"Is it possible to detect a carryover, e.g., from a cooling lubricant, into subsequent process steps and identify the source?"|
In contrast to conventional electrical methods of characterisation, 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 electromagnetic wave emitted interacts with the material and can be measured.
The advantage of ultra-wideband impedance spectroscopy over other technologies lies in the wide-frequency range that is covered. This allows for the detection of various 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 difficult to disturb|
