Tri-axial accelerometers consist of three sensing elements within a single housing. VPS vibration sensor 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. Tri-axial 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 sensor is epoxy-sealed and comes with rugged integral cabling providing a secure connection and reliable data output.
