Bently Nevada 330130-060-11-05 FluidLoc Extension Cable

Bently Nevada 330130-060-11-05 Armored FluidLoc Extension Cable

Product Introduction

This Bently Nevada 330130-060-11-05 extension cable represents a premium solution for critical machinery monitoring. It connects non-contacting proximity probes to Proximitor sensors in harsh industrial environments. Specifically, this model offers a 6.0-meter (19.7 feet) length with both armored jacketing and FluidLoc sealing. The FluidLoc feature actively prevents oil and other liquids from leaking through the cable interior. Consequently, this cable is particularly valuable for turbine, compressor, and pump applications where oil exposure is common.

Technical Specifications

The Bently Nevada 330130-060-11-05 delivers a nominal capacitance of 69.9 pF/m (21.3 pF/ft). Its center conductor DC resistance measures 1.32 ± 0.21 Ω. Meanwhile, the outer conductor resistance is 0.39 ± 0.08 Ω. The cable integrates seamlessly with Proximitor sensors that require -17.5 Vdc to -26 Vdc without barriers. Furthermore, the system output resistance is 50 Ω. The supply sensitivity remains below 2 mV change per volt of input variation.

This extension cable supports a linear range of 2 mm (80 mils). The effective measurement zone starts at approximately 0.25 mm (10 mils) and extends to 2.3 mm (90 mils). Additionally, the 3300 XL system maintains excellent stability in humid conditions. Specifically, it shows less than a 3% change in Average Scale Factor after 56 days of 93% relative humidity testing per IEC 68-2-3.

Mechanical and Environmental Features

The Bently Nevada 330130-060-11-05 includes a rugged armored jacket weighing 103 g/m (1.5 oz/ft). This armor provides exceptional protection against physical damage, crushing, and abrasion. Moreover, the cable incorporates patented CableLoc technology for 330 N (75 lbf) pull strength. This ensures the connection between probe cable and probe tip remains secure even under tension.

The defining feature of this model is the FluidLoc cable option. This design prevents oil migration through the cable's interior, a common failure point in standard cables. Therefore, operators can confidently install this cable in environments with continuous oil exposure. The gold-plated ClickLoc connectors further enhance reliability by resisting corrosion and maintaining low contact resistance.

Approvals and Safety Compliance

This 330130-060-11-05 carries the 05 approval option, covering CSA, ATEX, and IECEx certifications. These approvals make it suitable for installation in potentially explosive atmospheres. When barriers are used in the circuit, the power requirement shifts to -23 Vdc to -26 Vdc. Operation at voltages more positive than -23.5 Vdc may result in a reduced linear range. For field wiring, we recommend 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable.

Installation Guidelines

First, ensure the probe is gapped at 1.27 mm (50 mils) for optimal system performance. Next, connect the 330130-060-11-05 using the gold-plated ClickLoc connectors until they click securely. The FluidLoc design requires no additional sealing compounds at the connection points. However, standard silicone tape is included for added protection if needed. For applications with turbine oil, the FluidLoc feature eliminates the need for this tape. Finally, the maximum field wiring distance between the Proximitor sensor and monitor is 305 meters (1,000 feet).

Frequently Asked Questions (FAQ)

1. What makes the 330130-060-11-05 different from standard extension cables?
This model includes both armored protection and FluidLoc oil-sealing technology. The FluidLoc feature prevents oil from leaking through the cable interior, making it ideal for turbine applications.

2. Is the Bently Nevada 330130-060-11-05 compatible with 5 mm probes?
Yes. This cable accepts 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes without any adapter.

3. Can I use this cable in explosive atmospheres?
Absolutely. The 330130-060-11-05 carries CSA, ATEX, and IECEx approvals for hazardous area installation.

4. Does the FluidLoc option require special maintenance?
No. The FluidLoc design is maintenance-free and requires no periodic re-sealing. Simply connect it properly and it performs continuously.

5. What is the maximum distance between sensor and monitor?
The maximum field wiring distance is 305 meters (1,000 feet). Longer distances may cause signal rolloff at high frequencies.
