Rotary pipe joint
Element for connecting pipes that permits rotation at the joint (Figure D 36) . Rotary pipe joints are required wherever hydraulic energy must be routed from a stationary part of a machine to a moving
Digital cylinders (with several positions)
Cylinder design that is equipped with several, mostly binary tiered pistons that can be operated in any combination. Therefore with n pistons 2n-1 positions are obtained with a positioning accuracy th
Carrier sense multiple access with collision detection (CSMA/CD)
Monitoring process for buses with access without a defined sequence. Access collisions are detected. fieldbus
Binary
Two specific, mutually exclusive states, e.g. yes/no, correct/incorrect, on/off, O/ L or 0/1. The binary numerical system has the base 2. With n binary signals it is possible to define 2n states. Ther
One-way trip
Device for actuation in only one direction. In the other direct there is no actuation (CETOP RP 100).
Output module
Output module for a signal transfer element, e.g. main hydraulic stage in a proportional valve.
Response time of a cylinder
Time that is measured between the hydraulic fluid entering the cylinder and the start of the piston movement.
Electric-hydraulic analogy
The understanding of some processes in fluid technology is improved if use is made of the analogies that exist between electrical and hydraulic laws. Given specific boundary conditions, it is possible
Identification of a system
Process of searching for a mathematical model for an actual system which provides a satisfactory description of its stationary and dynamic characteristics. This makes it necessary to define the struct
