Product Overview
The Bently Nevada 330105-02-12-20-02-05 is a premium-grade 3300 XL 8mm Reverse Mount Proximity Probe, engineered for high-accuracy, non-contact measurement / shaft vibration and position in critical rotating machinery. As part / the 3300 XL series, it is fully compliant with API 670 standards, making it suitable for turbomachinery protection systems in the most demanding industrial environments.
This model features a reverse mount configuration with a probe length / 200 mm, making it ideal for installations where access to the front side / the mounting surface is restricted. The probe uses eddy current technology to deliver accurate measurements / both static and dynamic conditions on metallic targets, typically shaft rotors made / 4140 steel.
