Bently Nevada 330104-00-08-90-02-CN
Full Product Overview (3300 XL 8 mm Proximity Probe Series)
1. Product Introduction
The 330104-00-08-90-02-CN is a proximity probe from the 3300 XL 8 mm series, engineered for non-contact measurement of vibration and displacement in rotating machinery.
This model uses eddy current sensing technology to monitor the distance between the probe tip and a conductive surface, typically a shaft. It converts mechanical movement into electrical signals, allowing continuous monitoring of machine condition.
The “90” configuration indicates a longer system length, making it suitable for installations requiring extended cable routing. The “CN” suffix generally represents a localized configuration or specific connector/cable standard adapted for certain industrial environments.
This probe is widely used in heavy industry due to its reliability, durability, and ability to operate in harsh working conditions.
