Abstract:
A filter monitoring device which detects variances in pressure of fluid flowing through a filter element in a filter assembly includes (1) an indicator for conveying data of changes in the differential pressure of the fluid in the filter assembly and (2) a temperature sensor for transmitting data showing any changes in temperature of the fluid being filtered. A microcontroller converts data received about changes in differential pressure and temperature sensing means to digital format and transmits the data along two differential digital lines to a driver and output connector.
