testing
Polytec has developed a laser doppler vibrometer (LDV) which it claims overcomes the usual barriers to online vibration testing of products during the manufacturing process.
Polytec has developed a laser doppler vibrometer (LDV) which it claims overcomes the usual barriers to online vibration testing of products during the manufacturing process LDVs are widely used by research engineers in the automotive, computer drive, micromechanics and other industries, but their relatively high price, physical size and research type design have limited their wider use

Penny + Giles has added to its range the JC6000 robust multi-axis joysticks designed for demanding operator control applications.
The new Polytec IVS-200 industrial vibrometer sensor overcomes these limitations, with a new, self-contained compact design, at the lowest price for any equivalent performance.
The IVS-200 has been designed expressly for industrial, production and online testing applications.
It features an IP-64 protected and ruggedised housing which incorporates the complete LDV interferometer system, including all electronics for signal processing.
The IVS-200 provides a simple analogue voltage output signal proportional to the vibration velocity of the test object, for vibration frequencies up to 20kHz.
Compared with mechanical vibration transducers (accelerometers, strain gauges etc), Polytec laser vibrometers have the key advantage of being noncontact and non-mass-loading, with greater accuracy and without mechanical crosscoupling effects.
They operate at some distance from the test piece (typically 0.2 to 2m range with the IVS-200 units), allowing test parts to be measured on a production line.
This can reduce handling time and enable100% testing to be carried out, with significant improvements in quality confidence and end-customer satisfaction.
