Bently Nevada 330130-085-12-00 Extension Cable 8.5m

Bently Nevada 330130-085-12-00 FluidLoc Extension Cable with Connector Protector

Product Introduction

The Bently Nevada 330130-085-12-00 extension cable provides a reliable interconnection between the 3300 XL proximity probe and the Proximitor sensor. This version offers an 8.5-meter (27.9 feet) length with the FluidLoc cable option and an included connector protector. Specifically, the FluidLoc design prevents oil and other process liquids from leaking out of the machine through the cable's interior. Meanwhile, the connector protector adds an extra layer of defense against contamination at the probe-to-cable connection point. Additionally, both ends feature corrosion-resistant, gold-plated ClickLoc connectors for secure, low-resistance connections. Consequently, the 330130-085-12-00 delivers excellent signal integrity while protecting against fluid ingress and environmental contaminants. This model carries no hazardous area approvals (Option 00), making it suitable for general industrial environments where ATEX, CSA, or IECEx certifications are not required.

Technical Specifications

The Bently Nevada 330130-085-12-00 maintains consistent electrical performance for precision proximity measurement applications.

• Capacitance: The cable exhibits a typical capacitance of 69.9 pF/m (21.3 pF/ft). This low value minimizes signal attenuation over the 8.5-meter cable run.

• DC Resistance (RCORE): The center conductor to center conductor resistance measures 1.87 ± 0.28 Ω for this 8.5-meter length.

• DC Resistance (RJACKET): The outer conductor to outer conductor resistance is 0.56 ± 0.11 Ω.

• Connectors: Both terminations feature gold-plated ClickLoc connectors. These provide excellent corrosion resistance and maintain a secure mechanical connection under vibration.

• Pull Strength: The cable incorporates patented CableLoc technology, delivering a pull strength of 330 N (75 lbf). This robust design prevents accidental disconnection during installation or maintenance.

• Input Compatibility: Accepts one non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe.

• Linear Range: When configured with a 3300 XL system, the linear range spans from 0.25 to 2.3 mm (10 to 90 mils), corresponding to approximately -1 to -17 Vdc.

Environmental and Mechanical Parameters

This extension cable is engineered for dependable operation in general industrial environments.

• FluidLoc Technology: The FluidLoc cable option prevents oil and other liquids from leaking through the cable interior. This feature reduces fluid loss and minimizes environmental contamination risks.

• Connector Protector: The included connector protector shields the probe-to-cable connection from dirt, moisture, and other contaminants. This protection is especially valuable in dusty or wet industrial settings.

• Sealing Compatibility: When paired with 3300 XL 8 mm probes, the system employs a Viton O-ring to seal differential pressure between the probe tip and the case.

• Humidity Resistance: The complete system shows less than a 3% change in Average Scale Factor (ASF) after 56 days of testing at 93% humidity per IEC standard 68-2-3.

• Operating Temperature: All specifications are validated between +18°C and +27°C (+64°F to +80°F) at a maximum altitude of 2000 meters.

• Approvals: This model carries Option 00, meaning no hazardous area approvals are required. It is suitable for non-classified general industrial installations.

• Target Material: Performance characteristics apply to systems calibrated against AISI 4140 steel targets. Accuracy specifications do not apply to other target materials.

Installation Guidelines

Proper installation of the 330130-085-12-00 ensures optimal performance and long-term reliability.

• Power Supply: The Proximitor sensor requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption. With barriers, the range is -23 Vdc to -26 Vdc. Operating at voltages more positive than -23.5 Vdc may reduce the linear range.

• Field Wiring: Use 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable. The maximum allowable distance between the Proximitor sensor and the monitor is 305 meters (1,000 feet). For high-frequency signals, refer to frequency response graphs for rolloff characteristics.

• Output Resistance: The output resistance is 50 Ω, which matches standard monitoring system inputs.

• Connector Protection: Each cable includes silicone tape for optional use. However, Bently Nevada advises against using silicone tape in applications where the probe-to-cable connection is exposed to turbine oil. For such environments, the included connector protector is the recommended solution.

• Probe Gap: For AISI 4140 steel targets, set the probe gap to 1.27 mm (50 mils) for optimal linear performance.

• Pressure Sealing: While 3300 XL probes are designed with Viton O-ring seals, they are not pressure tested prior to shipment. Contact the custom design department if pressure testing is required for your specific application.

Frequently Asked Questions (FAQ)

Q1: What does the "00" approvals option mean for the 330130-085-12-00?
The "00" designation indicates that no hazardous area approvals (such as CSA, ATEX, or IECEx) are required for this cable. This model is intended for general industrial installations in non-classified areas where explosion-proof certifications are not necessary.

Q2: Is the 330130-085-12-00 compatible with both standard and XL series probes?
Yes, this cable accepts 3300-series 5 mm and 8 mm probes, as well as 3300 XL 8 mm probes. The gold-plated ClickLoc connectors ensure full compatibility across the 3300 product family.

Q3: What is the advantage of having both FluidLoc and a connector protector?
FluidLoc prevents oil from migrating through the cable interior and leaking from the machine. The connector protector separately shields the external connection point from dirt and moisture. Together, they provide comprehensive protection against fluid ingress and environmental contamination.

Q4: Can I use the silicone tape instead of the connector protector?
Yes, silicone tape is included as an alternative. However, Bently Nevada recommends using the connector protector when the connection will be exposed to turbine oil. For standard dry environments, either option may be suitable.

Q5: How does the 8.5-meter length affect signal quality compared to shorter cables?
The 330130-085-12-00 maintains signal integrity at 8.5 meters with its low capacitance of 69.9 pF/m and controlled DC resistance. For most industrial monitoring applications, this length performs identically to shorter cables within the specified linear range and frequency response.
