摘要： The present disclosure relates to methods and devices for reducing moisture, dust, particulate matter, and/or other contaminates entering a sensor. A sensor assembly may include a housing with an inlet flow port and an outlet flow port. The housing may define a fluid channel extending between the inlet flow port and the outlet flow port, with a sensor positioned in the housing and exposed to the fluid channel. The sensor may be configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A hydrophobic filter may be situated in the fluid channel, sometimes upstream of the sensor. When so configured, and during operation of the sensor assembly, a fluid may pass through the inlet flow port, through the hydrophobic filter, across the sensor, and through the outlet flow port.

摘要： The present disclosure relates generally to sensors, and more particularly, to methods and devices for reducing moisture, dust, particulate matter, and/or other contaminates entering a sensor. In one illustrative embodiment, a sensor assembly includes a housing with an inlet flow port and an outlet flow port. The housing defines a fluid channel extending between the inlet flow port and the outlet flow port, with a sensor positioned in the housing and exposed to the fluid channel. The illustrative sensor is configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A hydrophobic filter may be situated in the fluid channel, sometimes upstream of the sensor. When so configured, and during operation of the sensor assembly, a fluid may pass through the inlet flow port, through the hydrophobic filter, across the sensor, and through the outlet flow port. The hydrophobic filter may be configured to reduce the moisture entering the fluid channel of the sensor.
