330130-030-13-05 Bently Nevada Armored FluidLoc Cable

330130-030-13-05 Bently Nevada Armored FluidLoc Extension Cable

Product Introduction

The Bently Nevada 330130-030-13-05 extension cable represents a premium interconnect solution for 3300 XL 8 mm proximity transducer systems in hazardous locations. This cable connects the 8 mm probe to the Proximitor Sensor, enabling precise shaft vibration, thrust position, and eccentricity measurements in critical rotating machinery operating in explosive atmospheres.

Manufactured in the U.S.A., this 3300 XL extension cable offers a 3.0-meter (9.8 feet) length with both an armored outer jacket and the advanced FluidLoc option. The armor delivers exceptional protection against crushing and abrasion, while FluidLoc technology actively prevents oil and other liquids from leaking out of the machine through the cable's interior. Additionally, the 330130-030-13-05 includes a connector protector for enhanced connection security.

What truly distinguishes this model is its comprehensive hazardous-area certification suite. Carrying CSA, ATEX, and IECEx approvals (05 suffix), this cable is suitable for installation in explosive gas and dust environments worldwide. Its electrical performance, including 1.32Ω center conductor resistance and 69.9 pF/m capacitance, guarantees accurate, low-noise signals over the full 3.0-meter length.

System Compatibility & Performance

This 3300 XL extension cable operates exclusively with 3300 XL 8 mm probes and Proximitor Sensors. The complete system delivers a linear range of 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). This range corresponds to an output voltage of approximately –1 to –17 Vdc.

Performance specifications are validated using an AISI 4140 steel target, a -24 Vdc power supply, and a 10 kΩ load. For applications involving different target materials, note that system accuracy and interchangeability specifications may not apply. The 330130-030-13-05 incorporates patented TipLoc and CableLoc molding methods, which significantly enhance the mechanical bond between the probe tip and body while providing exceptional pull strength. Such robustness proves essential in high-vibration environments like steam turbines, centrifugal compressors, and large generators.

Furthermore, the combination of armored construction and FluidLoc technology makes this cable particularly valuable for oil-wetted turbine bearing housings and gearboxes. The included connector protector adds an extra layer of security against environmental contamination and accidental disconnection.

Installation Guidelines

Proper installation of the Bently Nevada 330130-030-13-05 requires careful attention to total system length. Specifically, the extension cable length and the probe length must sum exactly to the Proximitor Sensor's total specified length. Any deviation can introduce measurement inaccuracies.

For field wiring between the Proximitor Sensor and the monitor, use 0.2 to 1.5 mm² (16 to 24 AWG) tinned, 3-conductor shielded triad cable. The maximum allowable field wiring distance is 305 meters (1,000 feet). However, longer runs may cause signal rolloff at high frequencies, so always consult the frequency response graphs provided in the product documentation.

Although each cable includes silicone tape as an alternative to connector protectors, we strongly advise against using this tape in applications where the probe-to-extension cable connection contacts turbine oil. The 330130-030-13-05 already provides superior FluidLoc protection and includes a connector protector, making silicone tape unnecessary in oil-wetted areas. When installing in hazardous locations, always follow the relevant CSA, ATEX, or IECEx installation guidelines and use appropriately certified barriers and wiring practices.

Frequently Asked Questions (FAQ)

Q1: What hazardous-area approvals does the 330130-030-13-05 carry?
A1: This model carries CSA, ATEX, and IECEx certifications (05 suffix), enabling installation in explosive gas and dust environments worldwide. These approvals make it suitable for refineries, chemical plants, and offshore platforms.

Q2: What is the difference between FluidLoc and standard extension cables?
A2: FluidLoc actively prevents oil and other liquids from leaking out of the machine through the cable's interior. This feature is essential for turbine bearing housings and gearboxes where oil migration poses operational and environmental risks.

Q3: Can I use the 330130-030-13-05 with non-3300 XL series probes?
A3: No. This cable is specifically engineered for 3300 XL 8 mm probes and Proximitor Sensors. Using it with other series may result in incompatible electrical characteristics and mechanical fitment issues.

Q4: How do I calculate the correct total cable length for my system?
A4: Add the probe length to the extension cable length. The sum must equal the total length specified for your Proximitor Sensor. For the 330130-030-13-05, the 3.0-meter extension is typically paired with a probe whose length complements the sensor's total requirement.

Q5: Does the connector protector provide additional environmental sealing?
A5: Yes. The included connector protector offers enhanced protection against moisture, dust, and accidental disconnection. When combined with the armored jacket and FluidLoc feature, the 330130-030-13-05 delivers comprehensive environmental protection for demanding industrial applications.
