The first "real" industrial Laser
Vibrometer
The new Polytec Industrial Vibrometer Sensor, IVS-200 is a self-contained compact design, at a low price.
Laser Doppler Vibrometers (LDV's) are widely used by research engineers in the automotive, computer drive, micro mechanics and other industries The development of many modern products would have been impossible without the contribution of LDV technology

Laser vibrometers help F1 engines rev higher
Polytec's HSV-series laser vibrometers are being used by F1 and Nascar engine manufacturers to characterise and improve the valve performance of engines.
Vibration measurement eases automotive production
Laser vibrometers are easy to set up and operate and can exchange data with existing CAE hardware and software.
LDVs are also an ideal tool for online testing of products during the manufacturing process.
Current applications include the testing of brake pads, turbo chargers, DC motors, gear boxes, domestic appliances such as washing machines, vacuum cleaners etc.
to micro devices such as micro-sensors, electronics and MEMS devices.
Up until now, the relatively high price, physical size and research-type design of LDVs has limited the wider use of such systems in production lines.
The new Polytec Industrial Vibrometer Sensor, IVS-200, The new Polytec Industrial Vibrometer Sensor, IVS-200 is a self-contained compact design, at a low price.
The IVS-200 has been designed expressly for industrial, production and on-line 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 20 kHz.
Compared with mechanical vibration transducers (accelerometers, strain gauges, etc), Polytec Laser Vibrometers have the key advantage of being non-contact and non-mass loading, with greater accuracy and without mechanical cross-coupling 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 whilst 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.
The IVS-200 vibration sensor is available now in quantities suitable for multi-point testing on production lines, or as a test evaluation kit to prove the system performance for subsequent installations. Request a free brochure from Lambda Photometrics ...
