1900/65A-01-00-01-00-00 high-reliability vibration monitoring sensor

1900/65A-01-00-01-00-00 is a high-reliability vibration monitoring sensor developed by Bently Nevada (now part of GE Vernova), belonging to the 1900 Series—a product line specialized in industrial rotating machinery condition monitoring. It is designed to measure bearing housing vibration (radial or axial) in medium-to-large rotating equipment (such as motors, pumps, compressors, and turbines), providing real-time vibration amplitude data to support equipment health diagnosis and fault early warning. Below is its comprehensive detailed information:

I. Core Technical Parameters
