Abstract

The invention provides a breakover detection device for use with a centrifugal separator. The device comprises a main chamber, a float in the main chamber operative to actuate switch contacts in response to the presence of liquid in the main chamber, an inlet and outlet for the main chamber arranged so that small volumes of liquid trickle from the inlet to the outlet without activating the float and large volumes of liquid at least partially fill the main chamber, thereby activating the float, electrodes in the main chamber for connection to circuitry discriminating between different liquids detected by the float in the main chamber. The device can detect the occurrence of breakover in a centrifugal separator, without leading to shutdown solely as a result of an increase in volume of the separated liquid.
