Bently Nevada 330130-040-13-05 Extension Cable 4m

Bently Nevada 330130-040-13-05 3300 XL Extension Cable

Product Introduction

The 330130-040-13-05 is a genuine Bently Nevada extension cable designed specifically for 3300 XL proximity probe systems. This 4.0-meter (11.5 feet) cable features armored construction with FluidLoc technology, providing robust protection against mechanical damage and fluid ingress. It includes a connector protector to safeguard the critical probe-to-cable interface during installation and maintenance. Furthermore, this cable carries multiple hazardous area approvals including CSA, ATEX, and IECEx, making it a versatile choice for refineries, chemical plants, and offshore platforms. The 330130-040-13-05 ensures reliable signal transmission between your 3300 XL probe and Proximitor sensor.

Electrical Specifications and Resistance Values

First, let us examine the electrical characteristics of this extension cable. The nominal DC resistance from center conductor to center conductor (RCORE) measures 0.88 ± 0.13 Ω for the 4.0-meter length. Meanwhile, the resistance from outer conductor to outer conductor (RJACKET) is 0.26 ± 0.05 Ω. These low, consistent resistance values ensure minimal signal attenuation across the cable. Additionally, the extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical, which maintains signal integrity over the total system length. The 330130-040-13-05 integrates seamlessly with 3300 XL 8 mm proximity probes and Proximitor sensors, preserving the system's overall accuracy.

Mechanical Construction and Armored Protection

The -13 option in the product code specifies armored construction combined with a connector protector. This armored layer provides exceptional resistance to crushing, abrasion, and impact damage, which proves critical in harsh industrial environments. Furthermore, the FluidLoc cable design prevents oil and other process liquids from leaking out of the machine through the cable's interior. This feature is particularly valuable in turbine and compressor applications where oil migration could compromise monitoring integrity. The armored extension cable weighs approximately 103 g/m (1.5 oz/ft), with a total weight of 0.618 kg for the 4.0-meter length. The connector protector supplied with each cable ensures the probe-to-extension cable connection remains free from contamination.

Hazardous Area Approvals and Global Compliance

The 330130-040-13-05 carries the -05 approval option, which includes three major certifications: CSA, ATEX, and IECEx. These approvals allow installation in explosive atmospheres across North America, Europe, and international locations. Specifically, the cable is suitable for use with 3300 XL proximity probes installed in Class I, Division 1 and Division 2 hazardous areas, as well as Zone 0, 1, and 2 environments. Always refer to the specific approval documentation and installation drawing 140979 for proper application. The multiple approvals simplify global procurement and reduce the need for region-specific cable variants.

Compatibility with 3300 XL Proximity Systems

This extension cable works exclusively with Bently Nevada 3300 XL 8 mm proximity probe systems. The system performance specifications assume a complete assembly comprising a 3300 XL 8 mm probe, this extension cable, and a 3300 XL Proximitor sensor. The system requires a power supply of -17.5 Vdc to -26 Vdc, with a maximum consumption of 12 mA. When used with barriers, the voltage range is -23 Vdc to -26 Vdc. The supply sensitivity is less than 2 mV change in output voltage per volt change in input voltage, ensuring stable readings. Additionally, the output resistance is 50 Ω, matching the Proximitor sensor's input requirements.

Installation Guidelines and Best Practices

Proper installation of your 330130-040-13-05 ensures optimal system performance. First, inspect the connector protectors before installation to confirm they remain intact. Next, use the provided silicone tape as an alternative to connector protectors, though Bently Nevada advises against silicone tape in applications where the probe-to-cable connection may contact turbine oil. The tape can degrade in oil environments and compromise the seal. Additionally, when routing the armored cable, avoid sharp bends that could stress the internal conductors. The recommended field wiring uses 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned conductors. Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet).

Packaging and Shipping Details

Each 330130-040-13-05 cable arrives in original factory packaging, which protects it from physical damage during transportation. The package includes the 4.0-meter armored extension cable with pre-installed connector protector. Additionally, silicone tape is included as an alternative sealing option. Please note that mounting hardware, probes, and Proximitor sensors are sold separately. We ship all orders via FedEx, UPS, or DHL with full tracking capabilities to ensure timely delivery to your facility.

Frequently Asked Questions (FAQ)

1. Can I use this cable with 3300 XL 5 mm or 50 mm probes?
No, the 330130-040-13-05 is specifically designed for 3300 XL 8 mm probe systems. Using it with other probe sizes may affect system accuracy and linearity.

2. What is the purpose of the connector protector?
The connector protector prevents contamination from entering the critical probe-to-extension cable connection point. This ensures reliable electrical contact and extends the service life of the connection.

3. Is the armored cable suitable for buried or conduit installations?
Yes, the armored construction provides mechanical protection suitable for conduit runs. However, always follow local electrical codes and Bently Nevada installation guidelines for proper routing.

4. How do I clean the cable connectors if they become dirty?
Use a lint-free cloth with isopropyl alcohol to gently clean the connector surfaces. Avoid abrasive materials that could scratch the contacts. Always allow connectors to dry completely before mating.

5. Does the 330130-040-13-05 include the silicone tape?
Yes, each cable includes silicone tape as a sealing alternative. However, Bently Nevada recommends using the connector protector for oil-exposed applications instead of the silicone tape.
