Product Overview

The Bently Nevada 330730-080-11-CN is a 3300 XL 11 mm extension cable with armored construction. This cable connects a 3300 XL 11 mm probe to a Proximitor Sensor. Cable length reaches 8.0 metres (26.2 feet) as specified by option 080. The connector and cable option 11 indicates armored FluidLoc cable construction. Agency approval option CN specifies country-specific certifications for this model. All components of the transducer system use gold-plated brass ClickLoc connectors throughout. ClickLoc connectors lock into place positively, preventing any connection from becoming loose. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body. Additionally, the CableLoc design securely attaches the probe cable to the probe tip with 330 N (75 lb) pull strength. For oil and liquid containment, the FluidLoc option prevents leaks through the cable interior.

Armored FluidLoc Construction (Option 11)

The 11 connector and cable option provides two critical features for demanding applications. First, flexible AISI 302 stainless steel armor surrounds the entire cable length. This armor resists crushing, cutting, and abrasion damage effectively. Second, the FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable interior. For turbine and compressor installations, FluidLoc proves absolutely essential. The FEP outer jacket covers the armor for additional chemical protection. Consequently, the 330730-080-11-CN survives harsh mechanical and fluid exposure environments.

ClickLoc Connector System

The 330730-080-11-CN uses gold-plated brass ClickLoc connectors at both ends. These connectors lock into place with a positive engagement mechanism. Vibration cannot loosen a properly mated ClickLoc connection under normal operating conditions. For harsh industrial environments, this reliability proves essential. All 3300 XL 11 mm probes and Proximitor sensors accept these connectors. The probe case configurations include several thread options. Unarmored thread options include ½-20, 5/8-18, M14 x 1.5, and M16 x 1.5 varieties. Reverse mount probes come with either 3/8-24 or M10 x 1 threads. The 330730-080-11-CN connects to any of these probe types seamlessly.

FEP Insulation & Cable Construction

Fluoroethylene propylene (FEP) insulation distinguishes this extension cable from standard options. FEP offers excellent chemical resistance and exceptional thermal stability. The triaxial construction provides two separate layers of shielding for noise rejection. Center conductor carries the probe signal with minimal loss. Inner coaxial shield returns the signal reference path. Outer coaxial shield connects to earth ground for noise protection. This triaxial design rejects common mode noise effectively. The 330730-080-11-CN maintains signal integrity over its full 8.0 meter length. Operating temperature spans -51°C to +177°C for extreme industrial environments.

Country-Specific Approvals (Option CN)

The CN approval option indicates country-specific certifications for the 330730-080-11-CN. These approvals meet local regulatory requirements for specific nations. For example, certain countries have unique flammability or environmental standards. The CN option serves markets with national certification requirements. Consult Bently Nevada documentation for exact countries covered by this option. For global applications without country-specific needs, order the 00 approval option instead. The 330730-080-11-CN satisfies local compliance for its intended destination.

System Linear Range & Gap Setting

When used with a complete 3300 XL 11 mm system, this extension cable supports specific measurement ranges. Linear range reaches 4.0 mm (160 mils) for standard operation. This range begins at approximately 0.5 mm (20 mils) from the target. Linear range extends from 0.5 to 4.5 mm (20 to 180 mils). Output voltage spans approximately -1 to -17 Vdc across this range. Extended DSL range reaches 0.5 to 5.0 mm (20 to 200 mils). Output voltage extends to -19 Vdc in this extended range. However, the extended DSL range does not apply when using zener barriers. The recommended gap setting measures 2.5 mm (100 mils). The 330730-080-11-CN does not alter these specifications at all.

Installation Guidelines

Follow these steps for proper installation of the 330730-080-11-CN.

1. Inspect both connectors for damage before beginning installation.

2. Connect one end to the 3300 XL 11 mm probe using ClickLoc engagement.

3. Connect the other end to the Proximitor Sensor using ClickLoc engagement.

4. Route the armored cable away from high voltage sources to avoid noise pickup.

5. Secure the cable with tie wraps every 30 cm to prevent movement.

6. Avoid sharp bends that could damage the FEP insulation or armor.

7. Verify the FluidLoc seal is intact at both connector ends.

8. Check continuity using the resistance specifications in the table above.

Note: The 330730-080-11-CN armored cable weighs 140 g/m, so support the cable properly along its route. Do not exceed the minimum bend radius of the armored construction. For country-specific approval documentation, contact Bently Nevada with your destination country.

Common FAQs

1. What is the length of the 330730-080-11-CN?

This cable measures 8.0 metres (26.2 feet) in total length. The 080 option code specifies this particular length. Other lengths are available with different option codes. For example, 050 indicates 5.0 metres. Choose the length that matches your probe-to-Proximitor distance. The 330730-080-11-CN with 080 suits most standard installations.

2. What does the FluidLoc option provide on the 330730-080-11-CN?

The FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable interior. For turbine and compressor applications where oil wicking along the cable is a concern, this feature proves essential. The 330730-080-11-CN with FluidLoc maintains machine integrity while providing reliable measurement signals.

3. What is the difference between armored and standard cable on the 330730-080-11-CN?

Armored cable (option 11) includes flexible AISI 302 stainless steel armor surrounding the FEP insulation. Standard cable weighs 45 g/m, while armored cable weighs 140 g/m. The armor resists crushing, cutting, and abrasion damage. For installations in harsh mechanical environments, the 330730-080-11-CN armored version provides superior protection.

4. What approvals does the 330730-080-11-CN carry?

The CN approval option indicates country-specific certifications rather than general approvals. Standard options like 00 carry no approvals. The CN option meets unique national standards for specific destination countries. Before ordering the 330730-080-11-CN, verify that CN approvals apply to your installation location.

5. What is the operating temperature range for the 330730-080-11-CN?

Operating temperature spans -51°C to +177°C (-60°F to +351°F). Storage temperature matches this same range. FEP insulation provides excellent thermal stability across this range. For this reason, the 330730-080-11-CN suits high-temperature turbine and compressor applications. The armored construction also withstands these extreme temperatures without degradation.
