Correction of characteristics
order to compensate for non-linearities , reduce hysteresis and the like. This kind of correction can involve additions, multiplications or substitution (Figure K 9) . It takes place during signal processing
Word
to a Byte, which contains 8 bits, a word is a group of as many bits as a certain type of computer can process in parallel. As a rule, this is the data bus width. Therefore, in an 8-bit processor, a word
Replacement orifice diameter
and d2 which are connected in parallel or in sequential, the diameter dE of a replacement orifice can be calculated. For sequential configuration the replacement orifice diameter is calculated with For
Reversing motor
The direction of rotation of a variable motor shaft can be changed, without changing the direction of the absorbed volume flow by moving the lifting element away from zero. Reversing motors are rarely
Fault diagnostics
Measures for fault detection, fault localisation and fault indication. This can be achieved by the provision of state signals to the machine controls that, by means of comparison with the setpoints , detect
Four position valve
valve that has a 4th switching position in addition to the three standard positions. The 4th position can be used to solve particular tasks, such as a fail safe position in the case of a failure of the electrical
Internal leakage
Leakage occurring inside a device. It is not visible from the outside, but can involve a loss of power. With pumps, for example, this may be a flow of leaking oil from the high-pressure side towards the
Anti-rotation element for cylinders
As the tube casing and piston of a cylinder normally have a circular cross-section, the pistons can rotate in the face of tangential forces. Where this is not permitted and is not prevented by the applied
Efficiency of pipe
and form-related losses — neither of which are related to pressure. As such, the efficiency of pipe can be expressed as follows: This means the higher the efficiency of pipe, the higher the operating pressure
Digital setpoint control
handling and signal processing arise in the setpoint branch (e.g. time profiles, ramps etc.). Such tasks can be resolved all the better digitally, the higher the effort for signal processing . This statement
