The OSA Oil Separator Alarm monitors the level of the separated liquid in oil/petrol separators and generates an alarm signal when it is necessary to empty the separator.
It consists of an alarm unit and an ES4 capacitance sensor for detecting the layer level. The unit has two relay outputs, audio/visual alarms, test and reset buttons, and also monitors the sensor for shorts or cable breaks in the sensor circuit. The ES4 capacitance probe is mounted at least 150mm below the normal level of the separator. When the oil or petrol layer reaches the critical level, the unit generates an alarm signal.
