His work has implications for various industries that require precise gas measurement and analysis.
Latest Patents
Estvander's latest patents include a "Solid electrolyte gas analyzer with improved circuit and housing." This invention features an analyzer circuit housed in an electronics housing and a probe housing for immersion in the gas of interest. The electronics housing mounts directly to the probe housing, preferably through a standoff. The analyzer circuit is powered by an AC line input and includes a switching power supply to convert the AC line input to DC power usable by the analyzer circuit. Additionally, the analyzer circuit includes a heater circuit that controls a heater in the probe housing, with the power supply and heater circuit automatically adjusting to different AC line input voltage levels.
Another significant patent is the "Diagnostic method and apparatus for solid electrolyte gas analyzer." This invention equips a solid electrolyte gas analyzer with a diagnostic circuit that intermittently measures the impedance of the solid electrolyte measurement cell. This measurement serves as an indication that the cell may need calibration or replacement. The diagnostic operation is performed in situ, while the solid electrolyte cell is exposed to the gas to be measured and heated to a controlled elevated temperature. The cell impedance is measured at a predetermined frequency by injecting a modulated current through the cell and measuring the resulting voltage drop.
