Application

The general purpose non-intrusive capacitance level switch provides reliable liquid level detection of water based conductive liquids with non-coating and/or scaling characteristics with a 1A relay output. Media examples include hydrochloric, sulfuric acid and water. The liquid level sensor is bracket mounted on the exterior wall of non-metallic tanks and applied as a high level alarm or low level alarm.

Features

Non-intrusive level detection through plastic or fiberglass walls

Installed with PE, PP or PVDF adhesive 3M mounting brackets

Rugged PSO enclosure rated NEMA 4X with conduit connector

60VA relay selectable NO or NC via power supply wiring polarity
