OSA Oil Separator Alarm - Oil and Silt

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. In addition, the maximum permissable silt/sludge level in the separator can be also be detected.

OSA consists of an alarm unit, an ES4 capacitance sensor for detecting the layer level and an ES8 Ultrasonic silt sensor. 
The alarm unit has 2 relay outputs, audio/visual alarms and also test and re-set buttons. The alarm unit monitors the sensors for short circuits or cable breaks in the sensor circuits.
