Product Introduction
The Bently Nevada 330703-005-040-10-01-00 3300 XL 11 mm Proximity Probe is a precision-engineered non-contact sensor designed to measure vibration, displacement, and shaft position in critical rotating machinery. Developed as part of the Bently Nevada 3300 XL Series, this probe provides highly accurate and stable measurement performance even in the harshest industrial environments.
With an 11 mm probe tip, the 330703-005-040-10-01-00 delivers exceptional sensitivity, linearity, and temperature stability. It is used primarily with Bently Nevada 3300 XL Proximitor Sensors and extension cables to form a complete transducer system that complies with API 670 standards for machinery protection.
The probe uses advanced shielding and coaxial cable design to resist electromagnetic interference (EMI), ensuring signal integrity in applications involving high electrical noise. Its rugged, corrosion-resistant construction allows long-term, maintenance-free operation in oil-filled, vibration-prone, and high-temperature industrial environments.
This model is ideal for turbine, compressor, and pump monitoring systems where precise shaft vibration or position data are critical for predictive maintenance and system protection.
