Abstract: A method for testing a heat transfer fluid based on a charged wire test (CWT) includes applying and measuring discharge current through a test circuit formed when a cathode and an anode are at least partially immersed in the heat transfer fluid in a container and a voltmeter coupled to the cathode and the anode is turned on during the CWT. The method includes measuring temperature of the heat transfer fluid during the CWT, determining a current profile based on the measured discharge current, and determining a temperature profile based on the measured temperature. The method includes determining a pass/fail status and/or a rank status of the heat transfer fluid based on pass/fail criteria based on the current profile and the temperature profile during an entire duration of the CWT.

Abstract: It is possible to reduce a decrease in accuracy of measuring the concentration of a measurement target gas even in a case where, in a mixture of gases, there is a gas greatly different from another gas in a rate of change in thermal conductivity with respect to temperature. The concentration measurement device includes a sensor configured to measure the concentration of a measurement target gas in a mixture of gases on the basis of thermal conductivity of the measurement target gas, the mixture of gases including two or more components, and a heating unit configured to heat the mixture of gases so that the concentration of the measurement target gas can be uniquely determined with respect to the thermal conductivity.

Abstract: A method for manufacturing at least one membrane system for a micromechanical sensor for the calorimetric detection of gases. A wafer-shaped substrate is provided. At least one reference volume is introduced from a front side into the wafer-shaped substrate with the aid of a surface or volume micromechanical process while forming a reference membrane covering the reference volume at least in some areas. At least one measuring volume, which is adjacent to the at least one reference volume, is introduced into the substrate from a back side or the front side of the wafer-shaped substrate while forming a measuring membrane. A wafer-shaped cap substrate is applied onto the front side of the wafer-shaped substrate. A membrane system and a component are described.
