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 from ground loops and RF interference.

The 780A-D2 is classifed for usage in Class I Division 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:

  • 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
  • Class I, Div 2/Zone 2 certified, non-incendive
  • Manufactured in an approved ISO 9001 facility
