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. Three different bracket materials makes attachment to tank easy. Great for non-metallic or FRP tanks up to 1" thick. Use as a high or low level switch. Accuracy: +/- 1mm in water.
