Filter monitoring system
A fluid filter monitoring system includes a filter relief valve movable in response to a pressure buildup caused by filter clogging to sequentially actuate a pair of pressure-operated switches. A temperature sensor senses the temperature of fluid in the hydraulic system. A control unit, including a...

| description | A fluid filter monitoring system includes a filter relief valve movable in response to a pressure buildup caused by filter clogging to sequentially actuate a pair of pressure-operated switches. A temperature sensor senses the temperature of fluid in the hydraulic system. A control unit, including a microprocessor, controls the energization of a plurality of indicators, depending upon the status of the temperature sensor, the pressure-operated switches and the duration of actuation of the switches. |
