The Vibration-Strobe (vbx) kit has an operating range of 30 to 50,000 flashes per minute. Is uniquely designed to provide precise, instantaneous synchronization to a number of data collectors and FFT analyzers triggered by an accelerometer. Built for portable applications, the vbx is the perfect lightweight phase analysis tool. The vbx allows for the measurement of phase without stopping the machinery to install reflective tape. Phase analysis is quick and accurate using the Filter Bandwidth Selector and the Relative Phase Adjustment. Unique "Tracking Filter" maintains phase lock to input pulse. The vbx can power and be triggered by accelerometers with or without data collectors.
