Model 993B-7-M12 General-Purpose Hermetic Triaxial Accelerometer

Brand: Wilcoxon Sensing Technologies
Request Information
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.
Features
  • 3 axis simultaneous sensing
  • Broad frequency response
  • Captive mounting screw
  • Hermetically sealed
  • ESD-protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
