Parameter Analysis

The 330730-040-03-CN offers low capacitance (69.9 pF/m) to maintain signal integrity over its 4-meter length. The armored design provides mechanical protection, while the connector protector shields against moisture and humidity. With a wide temperature range and high tensile strength, this cable is engineered for reliable performance in harsh conditions.

Application Scenarios

This extension cable is ideal for vibration monitoring on rotating machinery including turbines, compressors, pumps, and other critical equipment. It is commonly used in power generation, oil & gas, petrochemical, and manufacturing industries where accurate shaft vibration and position measurements are essential.

Installation Guide

Connect the 330730-040-03-CN between a 3300 XL 11 mm probe and a 3300 XL Proximitor sensor. Ensure the connector protector is properly seated to prevent moisture ingress. For installations where the connection is exposed to turbine oil, use the provided silicone tape instead of connector protectors. Secure the cable with appropriate supports to avoid strain on connectors.

Compatibility

This cable is compatible with Bently Nevada 3300 XL 11 mm probes and Proximitor sensors. It is designed for system lengths of 5 or 9 meters including extension cable. Field wiring between the Proximitor and monitor can be up to 305 meters (1000 feet) using three-conductor shielded triad cable.

Maintenance Advice

Regularly inspect the cable and connectors for signs of wear, corrosion, or damage. Keep connectors clean and dry. If the cable is exposed to harsh environments, periodic replacement may be necessary to ensure measurement accuracy. Always follow Bently Nevada guidelines for handling and storage.

Procurement Advice

When ordering the 330730-040-03-CN, verify the model number and options to match your system requirements. Consider purchasing spare cables to minimize downtime. Ensure you source from authorized distributors like TenBN to guarantee genuine parts and technical support.
