Calculations of statistical values are available as additional functions. The calculation of the statistical values of a module is based on the ADC signals. The statistical values are all calculated according to the same calculation interval. The calculation interval can be set in ibaPDA in 1 ms steps in the range 100 ms to 5000 ms. The calculation is performed in blocks.
General characteristic values:
|
Characteristic value |
Description |
|---|---|
|
Minimum |
minimum of the input signal |
|
Maximum |
maximun of the input signal |
|
Average |
arithmetic average of the input signal |
|
Root Mean Square (RMS) |
mean square value (effective value) of the input signal |
|
Peak |
maximum or minimum value (absolute) |
|
Peak-to-Peak |
difference between the largest value and the lowest value |
|
Crestfactor |
Crest factor (ratio of maximum to RMS) of the input signal |
|
Used Range |
peak-to-peak in relation to the measuring range |
Bandpass-filtered characteristic values
Six bandpass filters per channel are available for the bandpass-filtered characteristic values. The bandwidth of the BP filters must be at least 50 Hz.
When IEPE mode is set, the characteristic values within a filter are calculated by default for acceleration or can be switched to velocity.
In 24V mode, calculations are either not integrated or are performed with switchable integration.
