Abstract
According to one aspect, a lubricant level sensing system for an actuator is provided. The lubricant level sensing system includes a pressure port in an outer housing of the actuator, a pressure sensor, and a pathway from the pressure port to the pressure sensor. The pathway establishes fluid communication between the pressure sensor and a free volume of an internal cavity of the outer housing relative to a lubricant level in the internal cavity such that the pressure sensor detects a pressure of the free volume used to derive the lubricant level.
Claims8
A lubricant level sensing system for an actuator, the lubricant level sensing system comprising:
- a pressure port in an outer housing of the actuator;
- an external pressure sensor;
- and
- a pathway from the pressure sensor to establish fluid communication between the pressure sensor and a free volume of an internal cavity of the outer housing relative to a lubricant level in the internal cavity such that the pressure sensor detects changes in pressure of the free volume used to derive the lubricant level.
