Level switches that are activated by the movement or magnetic floats that activate reed contacts with the magnetic field.
There are many combinations from a single buoy that temporarily activates the contacts when passing them to several buoys where each one activates one or two contacts that are switched until the buoy returns to its initial state. The devices with several floats facilitate the application because the level will be always reflected in the signal of the l microrruptor, avoiding problems arising from temporary activations of instability.
We have several models, shapes and materials. The parts in contact with the fluid can be made of several metals such as stainless steel, brass, Monel or polymers polypropylene, PSU, PVC, PTB, PTFE, PVDF, Buna, Kynar, Spansil, etc.
Through construction models of NIVOMAT, MADISON and VALCO ATEX Exia, Exd, CSA, CE, UL, NSF, OSHA, ABS, FCC, A3, etc.
It is also possible to construct multiphase levels where calibrated floats allows the interphase measurement between liquids of different density.
