ABSTRACT:
An apparatus and a method are provided for detecting accumulation of particulates in a fluid stream. A differential pressure switch is incorporated in the apparatus for detecting changes in pressure in the fluid stream passing through a strainer having a filter wherein the particulates accumulate at the filter. A body is insertable into a wall of the strainer wherein the body is in communication with the fluid stream. A pressure responsive device is responsive to changes in pressure in the fluid stream due to accumulation of the particulates. A signal producing device is activated to produce a signal upon detection of a predetermined pressure differential in the fluid.
