Churning losses
Losses arising in hydraulic pumps and motors when the housing is full of oil and the components are moving around inside. These are dependent on the rotation speed and — particularly during idling — m
Planetary motor
Hydraulic motor from the group known as annular gear motors which operate in accordance with the planetary principle. The distinguishing feature of planetary motors is how lots of displacement chamber
Pitot tube
Angled measuring device for determining the total pressure , i.e. the overall figure for the static and dynamic pressure associated with a fluid flowing at a subsonic rate. The pitot tube consists of
Piezoresistive effect
Change in the specific resistance of a metal under a mechanical load (mainly strain). The piezoresistive effect occurs with all metals (including metal strain gauges), although it is particularly pron
Piezoresistive pressure sensor
Pressure transducer based on the piezoresistive effect whereby pressure causes an elastic semiconductor structure to change, which in turn changes the values for resistances connected as a Wheatstone
