POLYTEC's portable multi-purpose, non-contact vibration system, the PDV-100 is a combination of state-of-the-art optics and digital signal processing.

Available from Warsash Scientific , the PDV-100 measures surface vibration velocity without contact, utilising laser doppler vibrometry (LDV) technology.

The system yields excellent measurement performance, ease-of-use and long-term calibration stability in a truly portable and robust package.

The PDV-100 is designed for non-contact vibration measurements where mobility and durability are important:

* Predictive maintenance of machinery.

* Operating vehicles, trains or airplanes.

* Buildings, bridges or other large outdoor structures.

* Multi-purpose field testing.

* Scientific expeditions

The lightweight signal processing equipment and optional transportation battery pack has enabled the PDV-100 to used in wide range of applications, from measuring the stability of World Trade Centre Building 4 during the recovery effort at "Ground Zero", to the vibration measurement of bees in a South American jungle by a scientific research team, and measuring vibrations on high tension/high voltage cables.

The system's digital signal processing provides superior performance with an improved velocity resolution and its digital signal interface to data storage or processing guarantees data accuracy and minimises EMC interference.
