Bently Nevada manufactures this extension cable in the U.S.A. for the 3300 XL transducer system. The cable length option is 080, which equals 8.0 meters (26.2 feet). The connector and cable option is 03, indicating armored cable with connector protectors. Meanwhile, the agency approval option is 05, representing Multiple Approvals for international installations. Therefore, this 3300 XL Extension Cable suits demanding applications requiring both mechanical robustness and regulatory compliance.

Technical Specifications

Cable Length and Type

The cable length is 8.0 meters (26.2 feet). This length suits most machinery monitoring installations. The connector and cable option 03 provides two key features. First, the cable has flexible armor for mechanical protection. Second, connector protectors are included for humid environments. Thus, the 330730-080-03-05 offers enhanced durability compared to standard unarmored cables.

Agency Approvals

The agency approval option 05 indicates multiple international approvals. These include certifications for hazardous area installations. Consequently, this cable meets global regulatory requirements. For specific approval details, consult the product documentation or contact Bently Nevada directly.

Cable Construction and Material

The extension cable uses 75 Ω triaxial construction. The insulation material is fluoroethylene propylene (FEP). The armor consists of flexible AISI 302 stainless steel. Additionally, the armored cable has an FEP outer jacket for chemical resistance. For reference, armored extension cable weighs approximately 140 g/m (1.5 oz/ft).

Connector Protectors

This version includes connector protectors as standard equipment. These protectors provide additional protection in humid or moist environments. Bently Nevada recommends connector protectors for all installations. As an alternative, silicone tape comes with each extension cable. However, do not use silicone tape where connections will contact turbine oil.

Electrical Specifications

The extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. For an 8.0 meter cable, the DC resistance shows specific values. Resistance from center conductor to center conductor is 2.0 ± 0.5 ohms. Similarly, resistance from coaxial conductor to coaxial conductor is 0.6 ± 0.2 ohms. Consequently, these low resistance values ensure accurate signal transmission from probe to Proximitor.

Temperature Range

The operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). Therefore, this wide range suits extreme industrial environments. The FEP insulation maintains flexibility across this entire range. As a result, the 330730-080-03-05 performs reliably in both very cold and very hot conditions.

Field Wiring Specifications

Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG) wire. With ferrules, use 0.25 to 0.75 mm² (18 to 23 AWG) instead. Bently Nevada recommends using three-conductor shielded triad cable for optimal performance. The maximum field wiring length is 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. However, longer wiring may cause signal rolloff at high frequencies.

Linear Range and Gap Setting

The linear range is 4.0 mm (160 mils). Specifically, linear range begins at approximately 0.5 mm (20 mils) from target. This linear range extends from 0.5 to 4.5 mm (20 to 180 mils). For reference, this corresponds to approximately -1 to -17 Vdc. The extended DSL range is from 0.5 to 5.0 mm (20 to 200 mils), equaling -1 to -19 Vdc. Nevertheless, the extended DSL range does not work with zener barriers. The recommended gap setting is 2.5 mm (100 mils).

Compatibility and Connectors

This extension cable works with 3300 XL 11 mm Proximity Probes. It also works with the matching 3300 XL Proximitor Sensor. All components use gold-plated brass ClickLoc connectors. These connectors lock into place and prevent loosening from vibration. Thus, the complete transducer system maintains reliable operation.

Patented Technologies

The patented TipLoc molding method provides a robust bond between probe tip and probe body. Additionally, the CableLoc design securely attaches probe cable to the probe tip. This design provides 330 N (75 lb) pull strength. Therefore, these patented features ensure long-term reliability.

Probe Compatibility Details

The 3300 XL 11 mm probe comes in varying probe case configurations. For example, options include armored and unarmored ½-20, 5⁄8-18, M14 x 1.5 and M16 x 1.5 probe threads. The reverse mount probe comes standard with 3⁄8-24 or M10 x 1 threads. Additionally, the probe comes standard with a locknut containing pre-drilled safety wire holes.

FluidLoc Option

3300 XL Probes and Extension Cables can also be ordered with a FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable interior. For applications with potential fluid exposure, consider this specialized option.

Installation Guide

Follow these steps to install your 330730-080-03-05 correctly.

1. Power Down Equipment: Disconnect power from the monitoring system. This prevents electrical damage during installation.

2. Inspect the Cable: Check the 330730-080-03-05 for any shipping damage. Verify the connector protectors are present and undamaged.

3. Connect to Probe: Align the ClickLoc connectors on the probe and extension cable. Push together until you hear a distinct click.

4. Connect to Proximitor: Attach the other end of the cable to the Proximitor Sensor. Ensure the ClickLoc connector locks securely.

5. Install Connector Protectors: Slide the connector protectors over each connection point. Twist until they seat firmly against the connector body.

6. Secure the Cable: Route the armored cable along a protected path. Avoid sharp bends and high-temperature sources.

7. Verify the Connection: Gently tug each connection to confirm locking. The CableLoc design provides 330 N pull strength for reliability.

Frequently Asked Questions (FAQ)

1. What is the difference between option 03 with approval 00 versus option 03 with approval 05?
Option 03-00 has no agency approvals. Option 03-05 includes Multiple Approvals for international hazardous area installations. Therefore, the 330730-080-03-05 suits facilities requiring certified equipment.

2. Can I use this extension cable with the 8 mm Proximitor Sensor?
Yes, the 3300 XL series uses the same connector interface for both 8 mm and 11 mm systems. Thus, the 330730-080-03-05 works with both probe sizes.

3. What is the maximum total system length for this extension cable?
The 3300 XL system allows 5 or 9 meters total length including probe and extension cable. For example, this 8.0 meter cable requires a 1 meter probe for a 9 meter system.

4. Why should I use the included connector protectors?
Connector protectors prevent moisture ingress in humid environments. Unlike silicone tape, they provide reusable protection. For turbine oil applications, connector protectors are strongly recommended over silicone tape.

5. How do I know the ClickLoc connection is secure?
The gold-plated brass ClickLoc connectors produce an audible click when fully engaged. You should also feel the locking mechanism engage. As a final check, always perform a gentle pull test to confirm security.
