Vibration measurement

Polytec has released a modular vibrometer controller to meet the needs of advanced vibration measurement applications. The design adds digital processing with a range of features that make non-contact vibration analysis more precise, simple and flexible. The OFV-5000 includes improved vibration resolution and dynamic range from digital/analog decoders, remote focus and focus memory with the advanced OFV-505 sensor head, more capacity for a wider range of modules and digital filtering.

The OFV-5000 controller is designed to accept a choice of signal processing modules, each optimised for different frequency, velocity or displacement performance. Each module is therefore tuned for different measurement tasks by making the best use of the vibration information in the Doppler signal obtained by the sensor head.

By selecting from a choice of different analog and/or digital decoders, performance can be precisely tailored to match the demands of the application. Several compatible stand-optic and fibre optic sensor heads are available to meet specific needs for robustness, flexibility and ease of use.
