Polytec, Inc. Portable Digital Vibrometer PDV-100

Vibration measurements are made easy with the PDV-100. After focusing the laser beam on the vibrating object the measurement 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 without any loss of accuracy. Available accessories include the PDV-BS transportation bag with integrated lithium ion batteries for nominal five hours operation time, the VIB-A-T01 tripod and a USB-based 2-channel data acquisition VibSoft-20 fornotebook operation
