Model 787-500-D2 Class l, Div. 2 Certified Low-Frequency Accelerometer

Brand: Wilcoxon Sensing Technologies
Wilcoxon’s side-exit broadband sensor is certified for usage in hazardous areas. The high-sensitivity accelerometer offers an interior sensing element capable of producing 500 mV/g outputting clear signals at low vibration levels. The low-end frequency response makes it ideal for slow-speed applications such as wind turbine generators and cooling towers. A high top-end frequency response offers clear signals for early bearing fault detection, gearbox wear, and other high-speed applications. The sensor is supplied with a 2 pin MIL-5015 connector. The 787-500-D2 is classified for usage in Class I Div. 2/Zone 2 locations where ignitable gases, vapors or liquids are handled, processed or used but are not usually present during normal operation and can only escape through accidental rupture, breakdown or leaks.
Features
  • High sensitivity
  • Clear signals at low vibration levels
  • Extended low frequency response
  • Class I, Div 2/Zone 2 certified, non-incendive
  • Mounts in any orientation
  • Hermetically sealed
  • Rugged design
  • ESD-protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
