Triaxial accelerometers consist of three sensing elements within a single housing. Wilcoxon’s 993A-5 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 are useful to monitor machinery with limited access to mounting areas. They provide full dynamic data over a wide frequency range in horizontal, vertical and axial directions from a single mounting location. The 993A-5 is epoxy-sealed and comes with rugged integral cabling providing a secure connection and reliable data output.
