Description
Overview
The Bently Nevada 330704‑000‑100‑10‑01‑CN is an 11 mm proximity probe designed for long‑range, high‑accuracy displacement and vibration measurement in large rotating machinery. As part of the 3300 XL Proximity Transducer System, it provides stable linearity, extended measurement range, and robust mechanical durability suitable for demanding industrial environments.
Design and Construction
This probe supports multiple mounting thread configurations—including ½‑20, 5/8‑18, M14 × 1.5, and M16 × 1.5—allowing flexible installation across a wide range of machine housings. The sensing system delivers a 100 mV/in/s sensitivity and supports 4–20 mA output, enabling integration with standard industrial monitoring and control systems.
The 330704‑000‑100‑10‑01‑CN incorporates Bently Nevada’s patented TipLoc molding process, which permanently bonds the probe tip to the body for enhanced mechanical strength. The extension cable uses gold‑plated ClickLoc connectors to ensure secure, vibration‑resistant electrical connections.
