KOBOLD Instruments, Inc. NEK - Compact Conductive Level Switch

Product Features Compact Design No Moving Parts Excellent for Dirty, Low-Viscosity or Aggressive Liquids PNP, NPN Transistor Switch or SPDT Relay Output PPS (Ryton®) or Polypropylene Bodies The NEK series compact conductive level switch is an excellent choice for economically monitoring the level of conductive liquids in tanks. The NEK series conductive level switch senses liquid level by applying a low AC voltage to a set of stainless steel electrodes. When a sufficiently conductive liquid is present, a small current will flow between the electrodes, resulting in switch activation. The NEK compact level switch is available with either a PPS (Ryton®) or Polypropylene body with 316-Ti stainless steel electrodes standard. This makes the NEK suitable for many compatible chemicals and media. The solid-state design has no moving parts, so the NEK is also a sure bet for level sensing of contaminated liquids as well as those with high solids content.
