Ultraviolet (UV) lamps are used commonly to disinfect water by killing bacteria. High Intensity Infra Red (IR) lamps are used in a variety of industrial processes to provide heat both for drying and curing processes. Correct operation is very important and can be determined by measuring current draw. Using an NK Technologies’ Current Operated Switch provides simple and quick verification. The on/off contacts of the switch may be used to simply indicate status to an operator using a lamp or wired to the input of a PLC preprogrammed with the necessary corrective action. Alternatively, NK’s Current Transducers may be used to provide an accurate measurement of the current draw by a UV, IR or other light source.
