FUNCTIONAL PRINCIPLE: Incremental inputs over time are the base
signals for measurement and evaluation of torsional vibrations and static
torsion. |
Further on this angular displacement signal may be converted to angular velocity or
acceleration. The programmable analog outputs are useful to store the measurement
as analog signal on tape. In parallel the signals are evaluated using a FFT algorithm
resulting in a 128 point spectrum.
The used measurement cycle may be defined by either a trigger input or by a known
number of increments per revolution.
 |
The static torsion is defined by using two trigger input signals in parallel to
the measurement inputs.
The final results (vibration, FFT, static angle) are output via the RS 232 interface and
may be further evaluated using the WinVA software (shipped
with the Vibration Analyzer DA2).
COMPLETE PACKAGE INCLUDING SOFTWARE WinVA: The software WinVA completes the system and guarantees a
user friendly operation.
A software package for Windows NT/95 is a scope of
supply of the Vibration Analyzer DA2. Additionally a serial cable for the RS 232
interface and a link cable for the operation of two DA2 (4 channel operation) is supplied.
 |
The settings of the Vibration Analyzer DA2 may be interactive set up and stored.
Measurement results may be online displayed, evaluated and stored in files.
A wide range of diagram types (waterfall, orbit, order tracking...) is available.
