The Fixturlaser NXA Runout Probe is a simple electronic tool designed to detect and measure shaft runout. The new tool represents a unique application of a linear variable displacement transducer (LVDT) to provide an easy-to-use but highly accurate measure of machinery problems that can confound the measurement and correction of shaft misalignment.
The Probe connects to the Fixturlaser NXA laser shaft alignment tool via Bluetooth. The NXA comes pre-installed with two firmware utilities (firmware version 4.0.0 or higher, activation may be required) that work with the Probe:
When measuring runout with the new NXA Runout Probe the best practice is to first measure the coupling for non-circular rotation. If runout is detected, the next step is to measure the shaft to determine if the runout is caused by a bent shaft versus an eccentric coupling.
