OSA Oil Separator Alarm

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 alarm unit has 2 relay outputs, audio/visual alarms and also test and re-set buttons and also monitors the sensors for short circuits or cable breaks in the sensor circuits.

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.
