Incrementing
Increasing a value by 1, i.e. counting up to higher values in individual steps.
Incremental position measurement
The distance to be measured is divided into equal elements (increments), which are then counted. The distance covered is obtained from the total for the increments from a single point of reference. Th
Incremental position encoder
Encoder whereby a bar pattern ( incremental position measurement ) is applied to a disc. As this rotates, the angle of rotation is determined via the number of increments counted during the period of
Parallel connection
Assembly option for hydraulic valves whereby the required valves for a function — e.g. directional valve, flow valves , high response proportional valves are assembled on top of each other on a base p
Top pressure limit
1. Top limit for any temporary exceeding of the calculated pressure where a device or system will still be functional (DIN 24 312). 2. Pressure ranges above around 800 bar are referred to as the top p
High pass (filter)
Electronic circuit that allows high-frequency signals to pass through unchanged, but results in a reduction in amplitude and a phase lead at low frequencies (Figure H 7) .
High torque motors
Term for — mainly slow-speed — hydraulic motors with very high displacement and therefore very high torque. High torque motors are generally designed as multi-stroke hydrostatic motors in terms of the
Run up time constant To
Time for the run up of a hydraulic motor from standstill to a given rotation speed. Applicable when the valve is fully open and there is no external torque, the time constant To max is a characteristi
Run up performance
Transient response of a hydraulic motor during the run up to working speed. In this context, the run up time constant is of most interest, as is any overshoot.
High pressure filter
Filter to be installed in the pressure line within a circuit. The housing, therefore, must withstand the nominal pressure associated with the system, although this is not the case for the filter eleme
