NivoPOINT MR series
magnetic float level switches
General
A magnetic float, moving alongside the protection tube tracking the level, activates the reed relays incorporated into the tube. After the float passes, the reed relays retain their output state. The device is capable of direct switching a load within its specification. All wetted parts are made of stainless steel. Various process connections as well as flanged versions (upon request) are available. Vertical adjustment of switching points is possible via mechanical gland. Only models with 2" process connection can be installed without dismantling.
