NE - Conductive Level Switch

Brand: KOBOLD Instruments, Inc

KOBOLD NE conductive liquid level switches are made in the USA and are designed for monitoring the level of moderately to strongly conductive liquids in tanks and vessels.

The simple design incorporates no moving parts and makes these conductive liquid level switches 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.

Conductive level switches operate through measurement of the electrical resistance between a sensing electrode and a reference electrode.

A complete NE Series level switch system consists of a reference electrode, a sensing (control) electrode and a relay/power supply like our NE-5048 Electrode Relay for Conductive Level Switches.

Up to six conductive electrodes may be mounted on each NE unit, for a total of up to six switch points.

A wide range of available materials, including 316-Ti stainless steel, Hastelloy® or titanium with optional polyolefin or PTFE coating of electrodes, makes the NE ideal for use with corrosive or dirty media.

The KOBOLD NE Conductive Level Switch Series also features the NEH Cable Suspended Conductive Level Switch for applications that require much longer probe lengths and for applications in tanks with low overhead clearance which restricts or complicates installation.
