Tech/Engineering / vibration measurement
 German term or phrase: Schwingpegel context: technical data for a vibration transmitter (sensor) "Optionell kann das 4-20 mA Normsignal mit einem Wechselstromsignal mit einer Amplitude von 0-1 mA (Spitze) überlagert werden. Dies wird zum Beispiel zur Frequenzanalyse des Schwingungssignales verwendet. Beispiel: Bei einem Messbereich von 8 mm/s und einem aktuellen Schwingpegel von 4 mm/s beträgt das Ausgangssignal einen Wert von 12 mA +/- 0.5 mA Wechselstromüberlagerung." Thanks in advance for your help.

 verlocity, oscillation level, frequency (bandwidth) Explanation:A ceramic gyro is a sensor that measures rotational (angular) velocity by oscillating a piezoelectric ceramic resonator with alternating voltage. The NECTokin Ceramic Gyro uses an extremely simple construction: piezoelectric ceramic rods, to which electrodes are attached during the printing process. This gives the sensor consistent quality and a wide range of applications, including shake detectors for hand-held video cameras. Piezoelectric ceramics change shape (stretch and shrink) when subjected to electric voltage. Alternately, they produce voltage when their shapes are altered. First, piezoelectric ceramic rods are placed horizontally at right angles to one another to form X and Y axes. Next, electrodes is attached to the X axis, and the two lines crossing the Y axis. Then when alternating electric voltage is applied to the electrodes on the X axis, the piezoelectric ceramic rods begin to oscillate back and forth along the X axis. If the electric potential of the two electrodes on the Y axis is measured at this time, there will be no change. This is because the piezoelectric oscillation is only occurring along the X axis, and no force has been applied to the Y axis. But if the ceramic rods are rotated on their axis, the oscillation of the X axis and vertical/Coriolis force are applied. When this occurs, potential appears in the electrodes on the Y axis in relation to Coriolis force. So it is possible to find out the rotation of the ceramic rods on their axis by looking at changes in electric potential. 3D Motion Sensor > Glossary ...

vibration amplitude

Explanation:
Vibration level shouldn't be used in your context because of the unit mm/s (according to the reference given below, vibration level should be reserved for dB).

--------------------------------------------------

Here\'s a conversion from VdB (the V stands vor vibration, not Volt) to in/sec, to show that this is about a level, not frequency.

Also, take a look at the definition of \'amplitude\' in the glossary (http://www.predict-dli.com/PdMXonweb/Resources/Glossary.html... The frequency is 1/\'Period T\', if memory serves.

Here\'s an example from an American site that actually deals with (mechanical) vibration, not any electromagnetic oscillation:

Look at CMCP-500 series, Description.

Sorry for causing confusion. The second \'level\' is to be taken as the general term, it\'s not the specific \'level\' used in the first reference. Mea culpa.

Kenneth clarified the rms problem, I suppose. Somewhat simplified, read \'rms\' as a suffix describing how the numeric value relates to the waveform. In the German sentence appears another of these suffixes - \'Spitze\', or peak-to-peak. You\'ll see this also as pp (e. g. 260 Vpp). It\'s not a unit.

--------------------------------------------------

Another clarification:
Spitze is peak (pk), while Spitze-Spitze is peak-to-peak (pp).

vibration frequency

Explanation:
The vibration amplitude is 4 mm, 4mm/sec is the frequency.

I have studied both of Klaus´ references carefully - as a musician I am very interested in vibration. The definition of amplitude he recommends says that amplitude has three meanings: amplitude of displacement, amplitude of velocity, and amplitude of acceleration. So far, so good. And since 4 mm/s is a velocity, it would be a velocity amplitude. But the other reference says \"a vibration velocity amplitude of 120 VdB is equivalent to 10 millimeters per second rms\". But rms is acceleration. So this text is confusing me completely.

I used to think I understood something about vibration (I play string instruments and use modern recording studios), but not any more.

I assume I am misunderstanding Klaus, too, since he first says you can´t call it a level, and then \"Here\'s a conversion from VdB (the V stands vor vibration, not Volt) to in/sec, to show that this is about a level\". That a level is an acceleration is clear to me, I know about levels, and dB. Maybe the author of the context was also confused, and should have written \"4 mm/sec rms\". In which case it would be an acceleration, or a level. But as given, it is surely a velocity.

6 hrs   confidence:
vibration amplitude

Explanation:
I'm not claiming the points, since the above answer has already been proposed, but maybe I can clear things up a bit:

First, this is an amplitude, since the text says that a +/- 0.5 mA ac signal will be superimposed on the output signal with a measurement range of 8 mm/s and a Schwingpegel of 4 mm/s, and with a peak ac output signal level of 1.0 mA. Since 0.5 mA is one half of 1 mA, and the signal varies by 0.5 mA in each direction, what is being measured is the amplitude of the vibration, and in fact the peak-to-peak amplitude (from one extreme to the other).

Secondly, with regard to velocity and accleration: it is possible to measure position (units of m, mm etc), velocity (m/s, mm/s etc) and accleration (m/s2/ mm/s2 etc) (those '2's are superscripts). Here what is being measured is the velocity of the vibration (mm/s).

See for example from the ref:

Eigenschaften
• Lastunabhängiger Schwingpegel von
10 m/s2, 10 mm/s und 10 µm
• Quarzgenaue Schwingfrequenz von
159,15 Hz (Kreisfrequenz 1000 s-1)
• Geeignet für Messobjekte bis 520 g

By the way, be careful with the '+/-': here it means that the ac signal varies by plus or minus 0.5 mA (ie, 1 mA peak-to-peak), (Germans love to do this), but +/- in English is usually used to express a tolerance for a value. Personally, I would reword this.

And a final by the way: 'rms' stands for 'root mean square' and refers to the 'effective' value of an ac signal -- it has nothing per se to do with acceleration.
