Présentation du produit
The Bently Nevada 330901-00-90-10-10-02-05 3300 NSv Proximity Probe is a precision-engineered non-contact displacement sensor designed for the accurate measurement sur shaft vibration, position, and phase reference in compact rotating machinery. Belonging to the 3300 NSv (Narrow Signal Version) family, this probe is optimized for applications where the installation space is limited, such as small turbines, compressors, gearboxes, and pumps.
This probe functions based on the eddy current principle, generating an electromagnetic field that interacts with the conductive shaft surface. Any movement sur the shaft alters this field, allowing the probe to output a precise voltage proportional to the displacement. When paired with a Bently Nevada 3300 NSv Proximitor Sensor and appropriate extension cable, it forms a complete measurement chain that meets API 670 standards for machinery protection and condition monitoring.
The 330901-00-90-10-10-02-05 model is known for its exceptional linearity, wide temperature tolerance, and strong immunitéy to environmental contaminants, ensuring stable and repeatable performance even under severe operating conditions such as oil-lubricated housings or high electromagnetic interference zones.
