The 2852-LS provides reliable level alarm and control of liquids and solids. The sensing probe continuously monitors the level changes in a vessel to alarm at user defined set points. It is typically used to control pumps and valves, alarm of high or low product conditions, or alert to potential overflow and dry conditions.
The 2852-LS sensing probe monitors the capacitance field around the probe. As the level of product increases or decreases in the vessel, the probe capacitance changes. This change is used to activate the relays for alarm and control.
