Parameter Analysis

The 330730-040-01-05 is engineered for low capacitance (69.9 pF/m) to maintain signal integrity over its 4-meter length. The armored construction provides mechanical protection in harsh environments. The cable’s temperature range (-51°C to +177°C) suits extreme industrial conditions. With a tensile strength of 270 N at connectors, it withstands typical installation stresses.

Application Scenarios

This extension cable is ideal for vibration monitoring on rotating machinery including turbines, compressors, pumps, and other critical equipment. It connects 3300 XL 11 mm proximity probes to proximitors, enabling accurate shaft displacement and vibration measurements.

Installation Guide

Connect the extension cable between the probe and the proximitor sensor. Ensure the connectors are clean and properly tightened. Use the provided silicone tape or optional connector protectors to seal connections, especially in humid environments. Avoid sharp bends and protect the cable from mechanical damage.

Compatibility

Compatible with Bently Nevada 3300 XL 11 mm proximity probes and 3300 XL Proximitor sensors. System length options: 5 or 9 meters including extension cable. Field wiring between proximitor and monitor can be up to 305 meters (1000 feet) using three-conductor shielded triad cable.

Maintenance Advice

Periodically inspect the cable for cuts, abrasions, or connector damage. Keep connectors clean and dry. If silicone tape is used, replace it during routine maintenance. Ensure the cable is not subjected to excessive tension or flexing.

Procurement Advice

Verify the model number 330730-040-01-05 matches your system requirements. Consider ordering spare cables to minimize downtime. For applications with liquid exposure, consider the FluidLoc option. For humid environments, order connector protectors.
