Optodyne's VS-5000 series Vibration Sensor is a noncontact, highly sensitive means of measuring displacement, velocity, and acceleration. Performing as a storage oscilloscope for mechanical vibration, the VS-5000 meets precision engineering requirements of microelectronic, aerospace, automotive, and R&D applications. A single axis (VS-5010) or the two-axis (VS-5020)system, provides measurement accuracy of ±0.5 ppm, resolution to ±0.05 microinch, speed up to 200 in/sec, and frequency response from do to 400 kHz. The extremely high signal-to-noise ratio of thes two-axis system (VS-5020) permits the user to measure simultaneously both target and background phenomena, while maintaining the integrity of each measurement.
