Bently Nevada 330906-02-12-05-05-02-05 3300 NSv Reverse Mount Probe

Présentation du produit

The Bently Nevada 330906-02-12-05-05-02-05 3300 NSv Reverse Mount Probe is a high-precision, non-contact displacement sensor designed for industrial machinery where reverse or compact mounting configurations are required. This probe is part sur the 3300 NSv series, engineered to provide reliable shaft position and vibration measurements even in constrained spaces where standard probes cannot be installed.

Operating on the eddy current principle, the probe measures variations in the electromagnetic field caused by the proximity sur a conductive target. This allows for accurate detection sur static shaft position and dynamic vibration signals, making it an essential component in rotor health monitoring and predictive maintenance systems. The reverse-mount design enhances flexibility for machinery layouts with limited space or unusual mounting orientations.

Its stainless steel housing ensures durability in challenging industrial environments, and its integration with 3300 NSv Proximitor modules supports full system compatibility for API 670 machinery protection standards. Typical applications include turbines, compressors, pumps, and motors.
