KD2, Duct Bank
These two illustrations were another relatively quick project for Decagon Devices, Inc. The KD2 Thermal is an instrument that measures the heat dissipation in various kinds of soils. This is a handy little instrument to have if you're installing electrical cables, for instance, and you need to know about heat tolerances. If you don't get it right, the cables could burn themselves out, causing all sorts of unpleasantness. The accuracy of this measurement is effected by the contact between the KD2's prong and the soil into which it's inserted. Bad contact means a bad measurement, which can be a problem in various kinds of soils. In such cases, thermal grease is used to create continuous contact. The first image is an illustration of precisely that. The second is an image of a duct bank (what a set of industrial-grade power cables might look like after they've been installed). Cheers.
