Model 786-500-IS Low-Frequency Intrinsically Safe Accelerometer

Brand: Wilcoxon Sensing Technologies
Request Information
Favorite
Wilcoxon’s intrinsically safe 786-500-IS sensor is certified for usage in hazardous areas and offers clear signals at low vibration levels. The sensor is designed with extended low-end frequency response and improved signal-to-noise ratio compared to other general-purpose models. It can be used to detect both low- and high-speed vibrations and is optimized for detecting vibration on slow turning machinery such as cooling tower fans and slow-speed gearboxes. 

The 786-500-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
  • Extended low frequency response
  • Clear signals at low vibration levels
  • Class I, Div 1/Zone 0/1 certified
  • Hermetically sealed
  • ESD protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
