NCW - Capacitive Level Switch

Brand: KOBOLD Instruments, Inc

The KOBOLD NCW Capacitive level switches are designed to monitor liquid levels in tanks.

They are comprised of a measuring probe and a connecting head with a plug-in evaluation module.

Different probes are available for various operating conditions.

There is a single probe for standard applications, a double probe with PVDF connection for aggressive media in non-metallic tanks, a single probe with an external grounding reference tube for non-metallic tanks or for media with a very low dielectric constant, and a single probe with a split head for liquid temperatures up to 392 °F.

The plastic NCW does not have any mechanical moving parts, minimizing the possibility of any mechanical wear.

The NCW is easy to maintain as the plug-in evaluation modules can be changed if required.
