Overview
The 2852-OWS Remote Mounted Oil Alarm provides reliable interface monitoring of oil/water separators, sump pits and containments for pump control and alarm. The sensing probe continuously monitors for the oil/water interface in a water filled sump or separator. It is typically used to control pumps, operate valves, or activate alarms.
The 2852-OWS sensing probe monitors the capacitance field around the active probe tip. As the volume of separated oil increases in the separator or is drawn down toward the probe tip, the probe capacitance changes. This change is used to activate the relay for oil alarm interface and control.
