High operating reliability with low maintenance requirements is one of the most important requirements for modern plants and systems. That’s why standards now also mandate electric monitoring of fluid levels.
The NS 1/GFK-MS (-VA) level switches are a particularly low-cost way to meet these requirements in more areas of mechanical and plant engineering. The materials used (GFK, hard PU and brass) offer good strength and resistance against strain and fluids. The heavy-duty, bistable reed contacts are mounted on a perforated rail inside the switching tube and can be adjusted. The shortest distance between two contacts is 80 mm. Subsequent adjustment or replacement of the contacts can be carried out without removing the switch from the tank.
