Bently Nevada manufactures this extension cable in the U.S.A., and it connects your 3300 XL 11 mm probe to the Proximitor Sensor. This 330730-080-01-05 uses high-quality materials for reliable performance. All transducer system components have gold-plated brass ClickLoc connectors. These connectors lock into place, and they effectively prevent loosening. Therefore, this 3300 XL Extension Cable works seamlessly with the complete 3300 XL transducer system.

Technical Specifications

Cable Length and Type

The cable length option is 080, which equals 8.0 meters (26.2 feet). Meanwhile, the connector and cable option is 01, indicating armored cable. Additionally, the agency approval option is 05 for Multiple Approvals. Thus, the part number 330730-080-01-05 specifies this exact configuration.

Cable Construction and Material

The extension cable material is 75 Ω triaxial cable, and the insulation uses fluoroethylene propylene (FEP) material. For added protection, the optional armor is flexible AISI 302 SST. This armored cable also has an FEP outer jacket. In terms of weight, unarmored cable weighs 45 g/m (0.5 oz/ft). In contrast, armored extension cable weighs 140 g/m (1.5 oz/ft).

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.

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 330730-080-01-05 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). This length runs between the 3300 XL 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). This equals -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).

Probe Compatibility

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. Meanwhile, the reverse mount probe comes with 3⁄8-24 or M10 x 1 threads. All components use gold-plated brass ClickLoc connectors. These connectors lock into place, and they effectively prevent loosening.

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. Thus, these patented features ensure long-term reliability.

Special Options

You can order FluidLoc cable option for the 330730-080-01-05. This option prevents oil and other liquids from leaking through the cable interior. Furthermore, the connector protector option provides additional protection in humid environments. Connector protectors are recommended for all installations. For example, silicone tape comes with each extension cable as an alternative. However, do not use silicone tape where connections will contact turbine oil.

Mechanical Specifications

Probe tip material is Polyphenylene sulfide (PPS). Similarly, probe case material is AISI 304 stainless steel (SST). Probe cable specification is 75 Ω triaxial, FEP insulated. Total probe lengths available are 1, 5 or 9 meters. Additionally, the probe comes standard with a locknut containing pre-drilled safety wire holes.

Installation Guide

Follow these steps to install your 330730-080-01-05 correctly.

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

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

3. Connect to Proximitor: Attach the other end of the 330730-080-01-05 to the Proximitor Sensor. Ensure the ClickLoc connector locks securely.

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

5. Apply Connector Protection: Install connector protectors over each connection point. For dry environments, you may use the provided silicone tape instead.

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

7. Set Gap Voltage: Adjust the probe gap to 2.5 mm (100 mils) recommended setting. This provides optimal linear range performance.

Frequently Asked Questions (FAQ)

1. What is the difference between armored and unarmored extension cable?
The 330730-080-01-05 has flexible AISI 302 SST armor with FEP jacket. Armored cable weighs 140 g/m versus 45 g/m for unarmored. Therefore, armor provides extra protection in harsh environments.

2. Can I use this extension cable with the 8 mm Proximitor Sensor?
Yes, the 3300 XL series uses the same connector interface. Thus, the 330730-080-01-05 works with both 8 mm and 11 mm systems.

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 avoid silicone tape in turbine oil applications?
Silicone tape degrades when exposed to turbine oil. Consequently, use connector protectors instead for these applications. The 330730-080-01-05 connector protector option provides better protection.

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.
