GLS 1000 is a float switch with PNP or NPN switching output signals presented by Wika. GLS 1000 is suitable for a multitude of media such oil, water, diesel and refrigerants. A permanent magnet built into the float, through its magnetic field, activates the semiconductor sensors built into the guide tube. The switching operation is contact-free and free from wear. Since no mechanical switching process is triggered, the sensor offers an unlimited number of switching cycles.
If the user requires, up to four switch points can be specified with a minimum distance of just 2.5 millimetres between each, which means even the smallest of level changes can trigger a switching pulse. It has an accuracy of ≤ 1 mm allows reliable level monitoring. GLS 1000 features a temperature output with Pt100/Pt1000 resistance for monitoring the temperature of liquids. As it is similar in shape and structure to its conventional counterparts, GLS 1000 digital float switch can be used as a replacement for classic PNP/NPN limit level switches, even though it uses electronic switching principles.
