Parameter Analysis

The 330730-080-03-CN extension cable offers an 8.0 metre length, suitable for many standard installations. The armored construction with AISI 302 SST armor and FEP outer jacket provides mechanical protection and environmental resistance. The connector protector option adds further protection for connectors in humid or moist environments, and is recommended for all installations. The CN agency approval ensures compliance with specific country requirements. The cable capacitance of 69.9 pF/m and DC resistance values are optimized for use with 3300 XL 11 mm probes and Proximitor Sensors, ensuring accurate signal transmission. The operating temperature range of -51°C to +177°C allows use in extreme conditions.

Application Scenarios

This extension cable is used in conjunction with 3300 XL 11 mm probes and Proximitor Sensors for monitoring and protection of rotating machinery, including:

• Steam and gas turbines
• Compressors
• Pumps
• Other rotating machinery where radial vibration, axial position, or speed measurements are required.

The armored cable and connector protector make it suitable for harsh industrial environments.

Installation Guide

Install the 330730-080-03-CN extension cable between the 3300 XL 11 mm probe and the Proximitor Sensor. Ensure that all ClickLoc connectors are securely locked into place to prevent loosening. The connector protector should be used to provide additional protection in humid or moist environments. Silicone tape is also provided with each 3300 XL extension cable and can be used instead of connector protectors; however, silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil. For field wiring, use three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. Observe the recommended gap setting of 2.5 mm (100 mils) for proper operation.

Compatibility

The 330730-080-03-CN is compatible with 3300 XL 11 mm probes and 3300 XL Proximitor Sensors. It features gold-plated brass ClickLoc connectors that lock into place. The extension cable is designed to work with 3300 XL series systems and meets the requirements for CN agency approval. It can be used with probes having various case configurations, including armored and unarmored ½-20, 5⁄8-18, M14 X 1.5, and M16 X 1.5 probe threads, as well as reverse mount probes with 3⁄8-24 or M10 X 1 threads.

Maintenance Advice

Regularly inspect the extension cable for signs of wear, damage, or loose connections. Ensure that connector protectors are intact and properly seated. If silicone tape is used, check for degradation, especially in oil-exposed environments. Verify that the cable is not subjected to excessive bending, pulling, or environmental extremes beyond its specifications. The patented CableLoc design provides 330 N (75 lb) pull strength, but avoid unnecessary stress on the cable. For optimal performance, keep connectors clean and dry.

Procurement Advice

When ordering the 330730-080-03-CN, verify that the cable length, connector option, and agency approval meet your specific application requirements. The model number 330730-080-03-CN indicates an 8.0 metre armored cable with connector protector and CN agency approval. Ensure compatibility with your existing 3300 XL 11 mm probe and Proximitor Sensor. For alternative lengths or options, consult the 3300 XL series catalog. It is recommended to procure genuine Bently Nevada parts from authorized channels to ensure performance and reliability.
