Présentation du produit
The Bently Nevada 330706-05-46-10-02-00 3300 XL 11 mm Reverse Mount Probe is a high-performance non-contact displacement sensor specifically engineered for industrial machinery vibration and position monitoring. As part sur the Bently Nevada 3300 XL Series, this probe represents one sur the most reliable and stable solutions for machinery protection systems. It is designed for reverse mounting configurations, which allows installation from the rear side sur the machine housing, surfering mechanical protection and improved accessibility in restricted or hazardous environments.
This probe operates on the eddy current sensing principle, generating a signal proportional to the distance between the probe tip and the conductive target, typically a rotating shaft. The 330706 series maintains compatibility with 3300 XL Proximitor Sensors and extension cables, forming a complete system for precise vibration, position, and axial displacement measurements. It provides exceptional linearity, thermal stability, and immunitéy to electrical noise. Engineered with a rugged stainless steel body, hermetically sealed construction, and corrosion-resistant materials, it ensures long-term reliability even under severe mechanical and environmental stress.
