Abstract
A hydraulic dissolved air measurement system and method are described that include a testing device, a pressure sensor, a piston actuation device, and a controller. The testing device includes a housing and a movable piston that define a measurement chamber configured to receive a hydraulic fluid sample from a hydraulic reservoir. The controller controls the piston actuation device to move the piston to expand the measurement chamber to an expanded state after the hydraulic fluid sample is received in the measurement chamber. The controller determines a volume change value that represents a volume increase of the measurement chamber based on the movement of the piston. The controller receives a pressure value from the pressure sensor that represents the pressure within the measurement chamber in the expanded state, and determines a dissolved air content of the hydraulic fluid sample based on the pressure value and the volume change value.
