Measurement tasks

Cepstrum analysis

A cepstrum is the 'spectrum of a spectrum' and is particularly

suitable for detecting regular structures in a frequency spectrum.

Above all, in the case of complex patterns with many harmonics and

sidebands - that frequently occur if roller bearings or gearings are

damaged- a cepstrum simplifies the evaluation of the measurement

data.

User-defined measurement quantities

As well as measurement tasks with fixed specified measurement

quantities, VIB XPERT provides measurement tasks where the

measurement quantities can be freely defined. The voltage (±30V,

AC/DC) or current (±30mA, AC/DC) can be connected as an input

signal and recorded as an overall value, as a time waveform* or as a

spectrum*. The assignment of the input signal to the measurement

quantity is specified by the 'Measurement quantity' and 'Unit'

parameters in the transducer setup (see P. 2-20).
Examples of user-defined measurement quantities:

- Measurement of the pressure as a current level (4-20mA, DC).

Connection to pressure transmitter.

- Measurement of the flow rate as a current or voltage signal (4-

20mA / 0-10V, DC). Connection to flow rate measuring device.

- Measurement of the sound pressure as a time signal or spectrum.

Connection to a microphone.

- Displacement measurement (inductive sensor VIB 6.640).

Only the following cables can be used as sensor cables:

VIB 5.433 - Connection cable for low voltage signals

VIB 5.434 - Connection cable for low current signals
