Abstract: A sensor system for sensing environmental conditions inside of a sealed enclosure includes a microcontroller and a thermal conductivity sensor for sensing inert gas concentration. The thermal conductivity sensor is operably coupled to the microcontroller. The thermal conductivity sensor includes a lamp with a filament that is exposed to the environment inside of the sealed enclosure, a thermal mass and a temperature sensor coupled to the thermal mass. The lamp is disposed at least partially within the thermal mass. A heater is coupled to the thermal mass.

Abstract: Glass edge sealant curing system including a method and apparatus for curing edge sealant around a stack of Thermopane windows. Infrared heating units abut three sides of the edges of a stack of Thermopanes on a conveyor. One of the infrared heating units moves in a path perpendicular to the conveyor travel, traveling in and out towards one of the edges of the glass. Once the three edges have been cured, the infrared heating unit across the conveyor raises up to allow the stack of panes to pass underneath and subsequently moves back into position for heating of the trailing edge of the stack of Thermopanes. The heaters are controlled according to one or more algorithms providing for appropriate energy consumption. Optical sensors are provided for determining the height of a stack of Thermopanes, as well as the length and width for appropriate heater energization, and thermopiles are provided for sensing the appropriate curing.
