Feedback system for continuously adjustable valves
Continuously adjustable valves generally have internal feedback of force and position feedback, which monitor the position in a corresponding to ensure the most precise possible correlation between th
Contamination measurement
The standard process to measure the number of particles is currently automatic particle counting on an opto-electronic basis (e.g. HIAC), but this does not specify the size of the particles. In contra
Modulation
Change in the characteristic size of a carrier frequency under the influence of electrical pulses representing the signal to be transmitted. In measuring and control technology , the preferred term te
Law of superposition
The law of superposition states: If an input variable (xe1) brings about an output variable (xa1) and also another input variable (xe2) brings about an output variable (xa2), therefore: if the law of
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
Temperature range
Area between the minimum and the maximum permitted temperature (e.g. of the medium, environment, etc.)
Clock signal
Signal supplied to the accumulating functional elements of a synchronous control via their clock. At signal value "L": Clock pulse and at signal value "0": Clock pause (DIN 19 237).
Delay valve
Pneumatic time element, which has the same construction as an RC element, i.e. a combination of a throttle valve and a small air container. After the container is filled, a valve is reversed ( Figure
Indication accuracy
Accuracy with which a pointer instrument indicates. It is generally defined in accuracy classes. Here it is important to state whether the accuracy relates to the permissible error limits on the value
Transient response
Describes the change of an over time when adding characteristic curves of the input signal (DIN 19 226) ( Figure U 5 ). The step function is a characteristic change of the input signal . . The or is t
