Abstract
A multi-sensing device is provided which includes a first sensor for sensing a temperature of the fluid flowing through the filter element, a second sensor for sensing a pressure generated by the fluid flowing through the filter element; and an indicator for indicating a condition of the filter system, and a microcontroller operatively coupled to the first and second sensors. The microcontroller executes instructions for receiving temperature data from the first sensor and pressure data from the second sensor; if the temperature data does not exceed a first temperature threshold, monitoring subsequent temperature data received from the first sensor until it exceeds the first temperature threshold; and if the temperature data exceeds the first temperature threshold: determining whether the temperature data exceeds a second temperature threshold and whether the pressure data exceeds a pressure threshold; if the temperature data exceeds the second temperature threshold, activating the indicator to indicate that the fluid is in an abnormal condition; and if the pressure data exceeds the pressure threshold, activating the indicator to indicate that the filter element is in a condemned condition.
