Differential Vibrometers

For the measurement of "out-of-plane" differential vibration Polytec offers dual-beam systems. Differential vibrometers allow vibration measurement between two points vibrating relative to each other. Specialized fiber optic probes allow the examination of locations that are difficult to access.

  • OFV-552 Fiber-Optic Interferometer 
     
  • HSV-2002 High Speed Vibrometer - particularly for high amplitudes

 

HSV-2000 High Speed Vibrometer

The HSV copes with high vibration speeds up to 30 m/s  and provides single or dual plus differential velocity and displacement measurement capabilities for high-speed applications like 

  • Valve train testing on motor sports engines
  • High power transducers, special drilling machines, as well as impact testing
  • And other measurement tasks requiring high speed LDVs

OFV-552 Fiber-Optic Interferometer

The OFV-552 differential sensor head gives the customer complete access to the probe beam as well as the reference beam.
   

  • Allows measurement of  relative motions between two points of a structure 

  • Widely used for valve kinetics studies, where one laser beam is focused onto the valve and the other onto the cylinder
