Bently Nevada 330130-085-10-05 FluidLoc Extension Cable

Product Introduction

The Bently Nevada 330130-085-10-05 extension cable provides a reliable connection for 3300 XL 8 mm proximity probe systems. This model stands out with its FluidLoc cable design, which specifically prevents oil and other liquids from leaking through the cable's interior. Consequently, it offers superior protection for turbine and compressor applications. Additionally, its gold-plated ClickLoc connectors ensure corrosion-resistant and secure connections.

Technical Specifications

Electrical Characteristics
The 3300 XL extension cable delivers consistent electrical performance for accurate vibration monitoring. For instance, its nominal DC resistance from center conductor to center conductor is 1.87 ± 0.28 Ω. Meanwhile, the resistance from outer conductor to outer conductor is 0.56 ± 0.11 Ω. Furthermore, the cable features a typical capacitance of 69.9 pF/m (21.3 pF/ft). These parameters ensure signal integrity across the 8.5-meter length.

Power and Supply Requirements
The Proximitor Sensor requires a power supply of -17.5 Vdc to -26 Vdc without barriers. It consumes a maximum of 12 mA. However, with barriers, the required range is -23 Vdc to -26 Vdc. Operation at a voltage more positive than -23.5 Vdc can result in a reduced linear range. Moreover, the supply sensitivity is less than 2 mV change in output per volt change in input, and the output resistance is 50 Ω.

FluidLoc and Approvals
The "10" connector protector option designates the specialized FluidLoc cable. This feature is critical for preventing oil from leaking out of the machine, making it ideal for wet environments. Additionally, the "05" approval option grants this cable CSA, ATEX, and IECEx certifications. Therefore, it is suitable for installation in potentially explosive atmospheres globally.

Mechanical Design and Installation

Physical Weight and Construction
This cable weighs 0.618 kg due to its specialized construction. Its design incorporates a patented CableLoc method that provides 330 N (75 lbf) pull strength. As a result, it securely attaches the probe cable and probe tip. The Bently Nevada 330130-085-10-05 also uses corrosion-resistant, gold-plated ClickLoc connectors for a durable connection.

Installation Guidelines
When installing, ensure the extension cable length and the probe length add up to the Proximitor Sensor's total length. For field wiring, we recommend using 3-conductor shielded triad cable, sized 0.2 to 1.5 mm2 (16 to 24 AWG). The maximum length between the sensor and monitor is 305 meters (1,000 feet). Remember, each extension cable includes silicone tape, but we do not recommend silicone tape for applications exposed to turbine oil.

Probe Compatibility
This extension cable accepts one non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe. The system's linear range begins at approximately 0.25 mm (10 mils) from the target, extending from 0.25 to 2.3 mm (10 to 90 mils).

Performance and Environmental Stability

System Accuracy
All performance characteristics apply to systems consisting solely of 3300 XL 8 mm components. The system accuracy and interchangeability specifications are valid when calibrated to an AISI 4140 steel target. Do not apply these specifications to systems using other target materials.

Environmental Robustness
The Bently Nevada 3300 XL system demonstrates high stability in harsh conditions. For example, the Average Scale Factor (ASF) changes by less than 3% when tested in 93% humidity, per IEC standard 68-2-3, for up to 56 days. This ensures reliable operation in demanding industrial environments.
