Abstract
A sensor apparatus includes a cylindrical sensor window defining an axis and a ring fixed relative to the sensor window and centered around the axis. The ring includes a liquid chamber, at least one nozzle, and an air chamber. The liquid chamber is elongated circumferentially around the axis. The at least one nozzle is fluidly connected to the liquid chamber and has a direction of discharge aimed at the sensor window. The air chamber is elongated circumferentially around the axis alongside the liquid chamber. The air chamber lacks inlets and outlets.
