Bently Nevada 330103-05-10-10-12-RU
Full Technical Specification, Product Overview, Applications, and Advantages
1. Product Introduction
The 330103-05-10-10-12-RU is a high-precision eddy current proximity probe designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery.
It is part of the 3300 XL 8 mm proximity probe series, which is widely used in industrial condition monitoring systems. The probe detects the distance between its conductive tip and a rotating shaft or target and converts the variation into an analog voltage signal.
This model is configured with enhanced environmental features and is adapted for installations that may require Russian standard certifications or custom requirements (RU). It is suitable for continuous operation in harsh industrial environments, including high temperatures, oil contamination, dust, and vibration.
