Parameter Analysis

The 330730-040-13-CN extension cable is designed to maintain signal integrity over its 4-meter length, with a typical capacitance of 69.9 pF/m. The armored construction with FEP outer jacket provides excellent protection against mechanical damage and chemical exposure. The FluidLoc option prevents oil leakage through the cable interior, while the connector protector shields connections from moisture and humidity. The cable’s temperature range of -51°C to +177°C ensures reliable operation in extreme conditions.

Application Scenarios

This extension cable is ideal for use with 3300 XL proximity probes in vibration monitoring systems for turbines, compressors, pumps, and other rotating machinery. It is suitable for applications where oil or liquid exposure is a concern, and where connector protection is needed in humid environments. The 330730-040-13-CN is commonly used in power generation, oil & gas, and petrochemical industries.

Installation Guide

When installing the 330730-040-13-CN extension cable, ensure that the system length (probe + extension cable) is either 5 or 9 meters as required. Use the provided silicone tape as an alternative to connector protectors, but avoid in turbine oil exposure areas. Connect the cable securely to the probe and Proximitor sensor, following the recommended torque specifications. Field wiring should use a three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the Proximitor and monitor.

Compatibility

The 330730-040-13-CN is compatible with Bently Nevada 3300 XL 11 mm proximity probes and 3300 XL Proximitor sensors. It is designed for use with 3300 series monitoring systems. Ensure that the total system length (probe + extension cable) is either 5 or 9 meters for proper calibration.

Maintenance Advice

Regularly inspect the extension cable for signs of wear, damage, or contamination. Keep connectors clean and dry. If the cable is exposed to harsh environments, consider using connector protectors for added protection. Periodically check the cable’s electrical characteristics, such as capacitance and resistance, to ensure they remain within specifications.

Procurement Advice

When ordering the Bently Nevada 330730-040-13-CN, verify the model number to ensure it matches your system requirements. Confirm the cable length, connector option, and agency approval. For international orders, check the specific country code (CN) to ensure compliance with local regulations. Purchase from authorized distributors to guarantee genuine parts and warranty support.
