Triaxial accelerometers consist of three sensing elements within a single housing. Wilcoxon’s 99B-7-M12 senses three mutually perpendicular axes at a single mounting location. Proponents of multi-axial sensors cite the increased speed of data collection, inherently consistent readings and reduction in wiring for permanent installations. Triaxial sensors monitor machinery with limited mounting areas, providing a full spectrum of data including horizontal, vertical and axial vibration levels at a single mounting location. The 993B-7-M12 is hermetically sealed and comes with the industry popular M12 connector.
