Model 780A General Purpose Compact Accelerometer

Brand: Wilcoxon Sensing Technologies
Wilcoxon’s top-exit 100 mV/g sensor is designed for monitoring areas with limited space. The general-purpose accelerometer is ideal for monitoring machine vibration on a wide range of rotating equipment such as motors, pumps, fans, compressors, turbines and generators. 

A 316L stainless steel casing provides rugged durability for most extreme environments. The sensing element is housed in a case-isolated Faraday shield, providing maximum protection against ground loops and RF interference.
Features
  • Lightweight for walkaround programs
  • Prevents ground loops in permanent mount applications with proper cabling
  • Can be submersed with proper connector
  • Hermetically sealed
  • ESD protected
  • Reverse wiring protection
  • Manufactured in an approved ISO 9001 facility
