Product Description
The 330130-085-00-CN is an 8 mm Eddy Current Proximity Probe from the Bently Nevada 3300 series of machinery condition monitoring equipment. The "-CN" suffix in the part number strongly indicates a specific configuration for the Chinese market, potentially relating to packaging, documentation, or a regional standard. This probe is a fundamental sensor that generates an electromagnetic field to measure the distance (gap) and dynamic motion (vibration) of a rotating metal shaft. It provides critical data for protecting expensive machinery from damage due to excessive vibration or thrust position failures.
Key Parameters and Specifications
The following table summarizes the key technical parameters for the 330130-085-00-CN.

Application Scenarios
This 8mm proximity probe is a core component for machinery protection in various heavy industries, particularly where metric threading (M10x1) is standard.
Power Generation: Monitoring steam turbines and gas turbines for shaft vibration, eccentricity, and speed (Keyphasor® reference). The robust design is suitable for the high-temperature environment near turbine shafts.
Oil & Gas: Vibration monitoring on critical high-speed equipment such as centrifugal compressors, pumps, and turboexpanders. Its use is often part of compliance with international machinery protection standards like API 670.
Hydroelectric Power Plants: Measuring shaft runout and vibration on large generators and turbines.
General Heavy Industry: Condition monitoring of large motors, fans, and gearboxes in sectors like pulp and paper, chemical, and water treatment plants.
