Thông tin sản phẩm

The 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


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 and AS9100 facility
