For Resistive Level Sensors Type: SNL
• Multi-level sensor for conductive liquids.
Fully static. Up to 5 levels (electrodes with adjustable length).
Maximum pressure 6 bar.
Maximum temperature 150°C (high-temperature version).
IP 66-rated, cable outlet or connection head; Teflon-coated electrodes with 316L stainless steel tips.

• Application
Level control or regulation
For tanks, reservoirs, or channels ….
Fluid presence/absence detection
(leak detection, empty pipe detection, pump control).

Resistive level sensor, based on changes in electrical resistance caused by the presence of fluid
between two electrodes. This resistance is converted into a binary signal using a level relay.

The sensor operates on the principle of conductivity between a common
electrode and one or more switching-level electrodes. The
presence of a liquid is detected by a change in resistance at the
contact point of the electrode.
