Abstract

See full text

A crust breaker bath detection system includes a cylinder defining a piston chamber. A piston is slidably displaced within the piston chamber by a pressurized fluid. A crust breaker rod connected to the piston is displaced through a crust layer into a bath having a bath voltage when the piston is displaced in the cylinder in a piston drive direction. A controller is in electrical communication with the cylinder. A conductive member is retained by and in electrical contact with the piston and in continuous contact with the cylinder. The conductive member defines a portion of a bath detection circuit including the crust breaker rod, the piston, the conductive member, the cylinder and the controller. The bath detection circuit is closed when the crust breaker rod contacts the bath such that the bath voltage is communicated to the controller by the bath detection circuit.
