Bently Nevada 3300 XL Series 21747-045-01 Proximitor Extension Cable with Armor

Overview

The 21747-045-01 (21747-045-01) serves as a critical link within the Bently Nevada 3300 and 3300 XL Proximitor Sensor systems. This specific extension cable is engineered to maintain high-fidelity signal transmission between the proximity probe and the Proximitor sensor, ensuring precise vibration and position monitoring in demanding rotating machinery environments. The inclusion of stainless steel armor provides superior mechanical protection against physical abrasion and fluid exposure common in industrial settings.

Detailed Specifications

Installation and Application

Proper implementation of the 21747-045-01 requires ensuring that the combined length of the proximity probe and the extension cable matches the required system length of the Proximitor Sensor (typically 5.0 or 9.0 meters). This armored version is ideal for internal machine housing or exposed conduit runs where moisture, oil, or mechanical impact risks are present.

FAQs

Can this cable be used with non-XL 3300 sensors?

Yes, the 21747-045-01 is backward compatible with standard 3300 series 5mm and 8mm systems, provided the total electrical length is calibrated correctly.

What is the benefit of the '01' Armor option?

The stainless steel braiding prevents the coaxial core from being crushed or kinked, which would otherwise alter the electrical capacitance and degrade the accuracy of vibration data.
