Abstract
Provided is a sensor wiper for a sensor pin used for fluid level detection. The sensor wiper comprises at least one swinging wiper having a wiper head for rotational association with a sensor pin, and an arcuate arm connected at a head end thereof to the wiper head. A plurality of inwardly directed radial elements are associated with the wiper head for engagement with the sensor pin. Sloshing action of fluids act upon the arcuate arm to move the wiping head, thereby causing the radial elements to engage and wipe the sensor pin.
