Latest Patents

**Thermocouple device.** This flame-detection device combines an outer thermocouple element selected for corrosion resistance and strong thermoelectromotive force with an inner element that also provides strong thermoelectromotive force. A solder-based junction layer secures their ends while avoiding the formation of an alloy that could have poor corrosion resistance if the elements were welded together.

**Thermocouple instrument.** This instrument contains a thermocouple element made from two dissimilar conductors, insulating material, and inner and outer protective metal tubes. The inner tube’s thermal expansion coefficient is equal to or greater than that of the outer tube, helping it remain firmly engaged within the outer tube and improving resistance to vibration and impact.
