KOBOLD Instruments, Inc. NE - Conductive Level Switch

Product Features For Conductive Liquids Only (>20 uS/cm) Multiple Switchpoints Usable with Dirty / Corrosive Media Highly Reliable Kobold's NE conductive level switch can be used to monitor the level of moderately to strongly conductive liquids only. The device works through measurement of the electrical resistance between a sensing electrode and a reference electrode. This simple design incorporates no moving parts and makes this device especially suitable for difficult applications, such as monitoring the level of low density liquids, high viscosity liquids, or liquids containing large quantities of suspended particulates. A complete NE level switch system consists of a reference electrode, a sensing (control) electrode and a relay/power supply.
