28 May 2017 Tablets & Capsules Level switches G series level switches use vibrating probes that mount on bins through 3/4-inch half-coupling to indicate when powder reaches or falls below switch location. GJ switch (left) detects low-bulk-density solids (10 to 15 pounds per cubic foot) that tend to pack or bridge. GS switch (middle) senses fine, low- bulk-density powders (5 to 10 pounds per cubic foot) such as fumed silica. GSS switch (right) is suitable for detecting extremely lightweight bulk solids, those less than 5 pounds per cubic foot, such as polymers. All level switches are approved for Class I, Group D; Class II, Groups E, F, and G; and Class III installations. They require no adjustments, have no moving parts, and are virtually wear-free.
