Float switches

Monitored levels are fundamental for an optimum operating status. If, in addition to level measurement, an alarm or other function is to be triggered in the event a specific level is exceeded or not reached, float switches are used. A float will switch a reed contact, and thereby the desired devices such as horns, pumps, or valves. Here, too, JUMO creates customer-specific solutions with the usual high production depth.
