The Goldammer NR 50 is a level regulator for tank inserts designed as a solenoid switch that operates without contact. It features bistable protective gas contacts within a switching tube, which can be configured as fixed or adjustable contact cartridges. The device utilizes a permanent magnet built into a float to switch contacts when the liquid level changes, with a switching difference (hysteresis) of 4 mm.
