Post-cure, overcure
1. Subsequent heat treatment (tempering) of certain elastomers whereby optimal characteristics do not emerge until the associated final linking occurs. 2. Unwelcome additional linking under the influence
Accumulator
1. A term only used infrequently these days for hydraulic accumulator . 2. Register in a computer system for carrying out mathematical operations, this register contains an operand prior to carrying out
Corner power
transmission that is given by the max. flow rate and the max. pressure (Figure E 1) : P E = Q max · p max = M 2 · 2πn 2. On constant pumps and variable pumps with pressure controller the corner power is
Contact ratio t p
within a limit the surface area moved past the surface should have a contacting ratio of at least 50% (1:2).
Intrinsically safe
1. Term from electrical engineering: An intrinsically safe device has a power level so low that it can be used in potentially explosive atmospheres. 2. Machine controls are intrinsically safe if, in the
Digital input step
Change in the input variable that changes the output variable by the smallest digital step (1 D = 1 Digit).
Pre-load pressure
1. Pressure intentionally generated by a resistance in a system (e.g. in the outlet line of a system). 2. Pressure to which the oil in a tank is subjected if the suction of the pump requires this. To that
Class of accuracy
actual value or of the end value. Example for electrical measuring instruments: 0.1 — 0.2 — 0.5 — 1 — 1.5 — 2 (VDI 2600).
Baud
Measure for the transmission speed for data: 1 baud = 1 bit/s. Named after the French engineer Jean Marie Baudot (1845—1903). data rate .
Calculated pressure
or systems are calculated under defined conditions to obtain functionality (see also DIN 2401, Part 1). The calculated pressure can be definitive for the operating pressure (corresponds to the actual pressure [...] operated. The calculated pressure corresponds to the rated value in accordance with DIN 40 200 (DIN 24 312).
