SENSOR FOR DETECTING AT LEAST ONE PROPERTY OF A FLUID MEDIUM IN AT LEAST ONE MEASURING CHAMBER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18044810 titled 'SENSOR FOR DETECTING AT LEAST ONE PROPERTY OF A FLUID MEDIUM IN AT LEAST ONE MEASURING CHAMBER

Simplified Explanation

The abstract describes a sensor that can detect properties of a fluid medium in a measuring chamber, specifically for detecting the fraction of hydrogen (H) in a gas being measured.

• The sensor includes three sensor elements:

 - The first sensor element detects the heat conductivity of the fluid medium and provides a measuring signal.
 - The second sensor element is made of a semiconducting metal oxide and provides a measuring signal.
 - The third sensor element detects a different physical property of the fluid medium and provides a measuring signal.

• An electronic evaluation unit is used to analyze the measuring signals from the three sensor elements.

• The electronic evaluation unit can adjust the operating parameters of the sensor elements, potentially optimizing their performance.

• This sensor design allows for accurate detection of the H fraction in a measuring gas, providing valuable information for various applications.

Original Abstract Submitted

A sensor for detecting at least one property of a fluid medium in at least one measuring chamber, for detecting an H fraction in a measuring gas. The sensor includes at least a first sensor element to detect a heat conductivity of the fluid medium and output a first measuring signal, a second sensor element including a semiconducting metal oxide and designed to output a second measuring signal, a third sensor element for detecting a physical property of the fluid medium, the third sensor element differing from the first sensor element and the second sensor element with regard to the detected physical property and being designed to output a third measuring signal, and an electronic evaluation unit for evaluating the first, second, and third measuring signal. The electronic evaluation unit is designed to change operating parameters of the first and/or second and/or third sensor element.
