UV & IR Lamp Status Monitoring
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.
Critical Lighting Systems Preventative Maintenance
High technology lamps have been developed for a variety of specialized industrial and commercial applications. These lamps are expensive and their useful life should be maximized. Installing an NK Technologies’ Current Transducer to measure the current draw of a lamp provides the information to determine the lamp’s condition by comparison to known characteristics. Intelligent control devices, like PLCs, are programmed to adjust the applied voltage or current to optimize the life of the lamp.
Lamp Failure Detection
The simple addition of an NK Technologies’ Current Operated Switch in a lighting circuit provides an isolated on/off signal to either a relay to automatically switch to a back-up lamp or signal a PLC to indicate lamp failure. The split-core model is designed for quick and simple installation for existing installations and the solid-core device provides a compact solution for new installations.
