2.2 Component Summary
Polytec assembles the vibrometer on the modular principle thus permitting a
user-specific configuration. The combination of the controller OFV-3001 with
the most useful decoders as well as a suitable sensor head provide the
solution to a multitude of measurement tasks. Thus a manageable number of
components cover a wide range of applications. A summary of the
components is shown in
.
The modularity is achieved initially through strict separation of optics and
electronics. Every decoder can be combined with every sensor head.
The controller is equipped with one of the two available velocity decoders as
standard. A maximum of two velocity decoders can be installed. The velocity
decoders are described in
As an option, the controller can be fitted with one of the four available
displacement decoders as well as be supplemented by a PC-based
displacement decoder (refer to
The various standard and fiber optical sensor heads comply with the different
requirements of the vibrometer’s optics. For every sensor head a selection of
lenses covers a wide range of stand-off distances.
