Float Switches Model NSM, NSP Application Liquid levels can be easily monitored with the following float switch types. Level control schemes can be implemented with at least two floats, whereby one operates as minimum contactor, and theother as maximum contactor. The switches are suited for applications where magnetic level switches are unsuitable due to the danger of the float jamming with dirt particles or deposits. Depending on the shape of the float and the material used, extremely aggressive, hot, soiled or pasty media can also be monitored with float switches. Description The float...

Description The KOBOLD level switches of model NEC have been developed for level monitoring of liquids and for direct pump control for all industrial applications. The float is supplied with a mechanical microswitch with very large switching capacity. The NEC comprises a stable plastic housing made of polypropylene with a total of five cavities sealed back-to-back. The instruments are thus practically unsinkable even when physically damaged. The level switches are available in following basic designs: O NEC-930: polypropylene float with mechanical contact, 5 m Hypalon® cable O NEC-HY930:...
