NIVOPOINT level switches can be installed in small stand-alone or built-in tanks. They are suitable for level indication of normal and explosive liquids and for level-control tasks. The instrument consists of a probe tube with magnetic float and a housing containing the connection terminals. The magnetic float moves alongside the protection tube tracking the level of the liquid and activating the reed switches. As the float passes a switch it changes the output state of the switch which retains this state latching until the level decreases and the float moves again along the respective switch to switch its state back. The parts of the device are made of stainless steel or plastic. Ex version is only available in stainless steel version.
The interaction of the magnetic float and the reed switches (incorporated in the protection tube) is the basis of the operation of the NIVOPOINT MR and MP magnetic float level switch series.
