With a total of 4 patents to his name, Ammann's work has advanced the understanding and application of fluid conductivity measurement.
Latest Patents
Ammann's latest patents include a "Method and device for detecting failures in inductive conductivity measurements of a fluid medium." This invention focuses on detecting open-circuit and short-circuit failures in electromagnetic measurements of liquid conductivity. The method involves immersing a sensor with at least two toroidal cores into the liquid, where one core carries an excitation coil and the other carries an induction coil. When an AC excitation voltage is applied, the induced current or voltage measured in the induction coil is proportional to the liquid's conductivity.
Another significant patent is the "Method and device for inductive conductivity measurements of a fluid medium." This invention also utilizes a sensor with two toroidal cores for electromagnetic measurement. The exemplary methods include converting the induced current at the induction coil into an alternating square-wave voltage, followed by rectification. A sample-hold circuit is employed to avoid transition time during the conversion, ensuring that the demodulated DC voltage accurately reflects the conductivity of the measured liquid.
