Abstract
The present invention relates to a water detection subassembly and method for forming same, for use in association with water detection system operating within a digital computing center. The subassembly includes a perforated protective semi-circular shield fitted about a fabric mesh supporting copper conductors connected to a low voltage source. The perforations of the shield are formed into two distinct patterns: The first series comprises sets of openings adjacent to the apex of the shield and periodically spaced therealong. Each opening has a common arcuate length L, a width W, and an internal spacing S and, more importantly, is of sufficient dimension to allow easy entry of aerosol mixtures of air and water droplets originating from above the shield. But each such opening (in combination with neighboring openings), does not weaken each shield unduly to the point the shield will collapse during usual housekeeping operations at the computer center, as when the computing equipment is repaired, replaced, or renovated. In a preferred embodiment, each opening has a common arcuate length L of about 1 inch, a width of about 1/16 to 1/8 inch, and a spacing S of between 2 to 3 inches fo…
