Installation and Application Guide

Step-by-Step Installation Tips

First, inspect the armored probe cable for any signs of damage that may have occurred during transit. Next, verify that the target surface finish meets the specifications required for the 3300 XL system. Then, carefully thread the probe into the mounting hole, applying the recommended torque of 15.2 N•m to achieve a secure fit without over-tightening. Finally, connect the ClickLoc connector to the extension cable, ensuring it is finger-tight. The connector protector helps guard against moisture and contamination.

Application Suitability

This armored Bently Nevada proximity probe is ideal for environments where the cable may be exposed to physical stress. Specifically, it is frequently deployed in steam and gas turbines, high-speed compressors, gearboxes, and large pumps. Additionally, its 1.0-metre length makes it suitable for installations where the junction box is located close to the probe mounting point, simplifying cable routing and reducing material costs.
