Model 787-500-IS Low-Frequency Intrinsically Safe Accelerometer

Brand: Wilcoxon Sensing Technologies
Wilcoxon’s side-exit broadband sensor is certified for usage 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 topend 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-IS sensor is classifed for usage in Class I Division 1/Zone 0/1 locations where ignitable concentrations of flammable gases, vapors or liquids are present continuously under normal operating conditions.
Features
  • High sensitivity
  • Clear signals at low vibration levels
  • Extended low frequency response
  • Class I, Div 1/Zone 0/1 certified
  • Mounts in any orientation
  • Hermetically sealed
  • ESD-protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
