The KOBOLD NEK compact conductive level switch is an excellent choice for small tank level monitoring. It senses level by applying a low AC voltage to a pair of 316-Ti stainless steel electrodes. In a suffi ciently conductive liquid, a small current will fl ow between the electrodes, resulting in switch activation. The NEK is available with either PPS or polypropylene bodies. The design has no moving parts so it excels in dirty liquids with a high solids content. The SS electrodes also enable it to handle many compatible chemicals and aggressive media in use today.
