Flip flop
Fast, bistable memory element for saving 1 bit. A number of flip flops connected in series are used as a shift register.
Error classification in measurements
A differentiation is made between systematic and random errors: Systematic errors : Are primarily caused by imperfections in the measuring instrument , the measuring procedure and the object measured.
Pressure stages
The pressure stages to be used in fluid technology are defined in DIN 24 312. They are taken from the preferred figure series R5 or R10 (Table D 3) . From these pressures a selection is defined in DIN
Laminar flow
Flow in pipes; flow in gaps. Below the critical Reynolds number (depending on the shape of the cross section), a laminar flow will apply. The individual elements of the fluid only move in the directio
Banked valves assembly (monoblock)
Design for controls predominantly found in mobile hydraulics where more than two functions need to be controlled. Banked valves assemblies are mainly controlled manually and are manufactured as a cast
Operating system
1. program in a digital computer system that together with the characteristics of the computer system forms the basis for the possible operating modes of the digital computer system and in particular
Preheater
Device used to add heat to the hydraulic fluid. It is required where the temperature of the fluid should also be constant at the start of the operating period. The preheating normally takes place elec
Auto-switching cylinders
Hydraulic cylinders , which automatically switch at both ends using an integrated switching device.
Pressure loss through a gap
The pressure loss Δp through a rectangular gap is calculated from the flow Q, the gap-width bg and the 3rd power of the gap-height hg, the overflow length lg of the gap as well as the density ρ and th
