Level Switches Model NKP

Description

The KOBOLD NKP is an economical level switch available
in polypropylene or PVDF wetted materials allowing for wide
compatibility with many aggressive liquids. It is distinguished
by its repeatable response, compact size, and high capacity
reed switch and is designed for installation into the sidewalls
of tanks. The plastic float, containing a magnet, moves as the
liquid level rises above or falls below the switchpoint. When
the magnet moves close to the reed contact, the switch
closes, completing the circuit. The switch function may be
changed from normally open to normally closed by merely
rotating it 180°. A simple and functional design makes the
NKP virtually maintenance free.
