PT PDV-100
Portable Digital Vibrometer
Customers requiring a turnkey solution, that is portable, affordable and rugged will fully appreciate the advantages of the PDV-100.

Polytec’s PDV-100 Portable Digital Vibrometer measures surface vibration velocity without contact, utilizing Laser Doppler Vibrometry (LDV) technology. The unique combination of state-of-the-art optics, digital signal processing and Polytec design experience yields excellent measurement performance, easeof-use and long-term calibration stability in a truly portable and robust package.

Vibration measurements are made easy with the PDV-100. After focusing the laser beam on the vibrating object the measure ment range is set via only two push buttons. An illuminated liquid crystal display shows the selected range, the amount of light returning to the PDV-100, and, if applicable, velocity over-range and low-battery warnings. Selectable high and low pass frequency filters condition the velocity signal to suppress low-frequency background vibrations or unwanted high-frequency signals. The analog velocity output interfaces to conventional analog signal processing and recording equipment. The digital velocity signal uses a transmission method proven in digital audio technology. It interfaces to digital inputs of modern recording devices or signal. analyzers with out any loss of accuracy. Available accessories include the PDV-BS transportation bag with integrated lithium ion batteries for nominal five hours operation time and VIB-A-TXX series tripods for firm mounting of the PDV-100 during critical measurements.
