Accumulator pressure monitoring system

摘要

An accumulator pressure monitoring system for monitoring pressure in a hydraulic circuit. The accumulator includes a first chamber filled with a gas, a second chamber filled with a liquid and a movable separator disposed between the first and second chambers. A pressure sensor measures the pressure in the first chamber; and a control unit receives pressure readings from the pressure sensor and compares the pressure readings to threshold pressure values and may control the accumulator based upon this comparison.
