  • Patent number: 10779429
    Abstract: A method for forming a flameproof transmitter is disclosed. The transmitter includes a flameproof housing including an interior surface, a display aperture and a shoulder adjacent to the aperture at first end of the housing. A transparent panel including an outer face and a perimeter is inserted into the housing from a second end to threadingly engage a fastener feature located on the interior surface of the housing such that the fastener element contacts the transparent panel and retains the transparent panel against the shoulder. A perimeter interface region between the perimeter of the transparent panel and the interior surface of the flameproof housing creates a perimeter gap that does not exceed a predetermined flameproof gap limit and a face interface region between the outer face of the transparent panel and the shoulder creates a face gap that does not exceed the predetermined flameproof gap limit.
