The future is digital

POLYTEC GMBH : 23 January, 2003  (New Product)
The PDV-100 fully incorporates digital signal processing, resulting in unequalled accuracy and long-term calibration stability. For the best resolution even at very low vibration levels three user-selectable velocity ranges are available (max. velocity 500mm/s, velocity resolution ≤ 0.05 μm/s). The PDV-100 incorporates three digital low pass and 1 analog high pass filter for reducing the acquisition bandwidth (max. bandwidth 22kHz) and removing spurious environmental vibrations.
Again Polytec is setting a new standard with the PDV-100 Portable Digital Vibrometer.

The PDV-100 is a ruggedized Laser Doppler Vibrometer for non-contact vibration testing. With its small size, low weight and low power consumption, it's the world's first Laser Vibrometer truly deserving the name portable.

In addition to the analog vibration velocity output, the PDV-100 features a digital signal interface in S/P-DIF standard that is compatible with many data loggers and data acquisition boards with digital input.

In the PDV-100 the best features of digital demodulation and the flexibility and portability of an „all-in-one' housing design are combined.
