The Bently Nevada 330130-075-10-05 extension cable serves as a dependable interconnection between the 3300 XL proximity probe and the Proximitor sensor. This particular version provides a 7.5-meter (24.6 feet) length with the FluidLoc cable option. Specifically, the FluidLoc design prevents oil and other process liquids from leaking out of the machine through the cable's interior. Additionally, this model includes corrosion-resistant, gold-plated ClickLoc connectors on both ends. Consequently, the 330130-075-10-05 offers superior protection against fluid contamination while maintaining excellent signal integrity. Moreover, its CSA, ATEX, and IECEx approvals make it suitable for installation in hazardous areas. Therefore, this cable is an ideal choice for turbine and compressor vibration monitoring applications.
The Bently Nevada 330130-075-10-05 delivers consistent electrical performance for precision proximity measurement systems.
Capacitance: The cable exhibits a typical capacitance of 69.9 pF/m (21.3 pF/ft). This low capacitance minimizes signal attenuation over the 7.5-meter run.
DC Resistance (RCORE): The center conductor to center conductor resistance measures 1.65 ± 0.25 Ω for this 7.5-meter length.
DC Resistance (RJACKET): The outer conductor to outer conductor resistance is 0.49 ± 0.10 Ω.
Connectors: Both terminations feature gold-plated ClickLoc connectors. These provide corrosion resistance and a secure mechanical connection that withstands industrial vibration.
Pull Strength: The cable utilizes patented CableLoc technology, delivering a pull strength of 330 N (75 lbf). This robust design prevents accidental disconnection during maintenance or operation.
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.
This extension cable is engineered to endure demanding industrial environments while maintaining measurement accuracy.
FluidLoc Technology: The FluidLoc cable option prevents oil and other liquids from leaking through the cable interior. This feature enhances environmental safety and reduces machine maintenance concerns.
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 cable carries CSA, ATEX, and IECEx certifications. Therefore, it is approved for use in potentially explosive atmospheres.
Target Material: Performance characteristics apply to systems calibrated against AISI 4140 steel targets. Accuracy specifications do not apply to other target materials.
Proper installation of the 330130-075-10-05 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 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.

Q1: What is the difference between the 330130-075-10-05 and the armored version?
The 330130-075-10-05 features FluidLoc technology but does not include an armored jacket. The armored version provides additional physical protection against crushing and abrasion. Choose the standard version for general industrial use where physical damage risk is low.
Q2: Is the 330130-075-10-05 compatible with existing 3300 series monitoring systems?
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 compatibility with all 3300 series Proximitor sensors.
Q3: How does the FluidLoc feature benefit my turbine application?
FluidLoc prevents oil from migrating through the cable interior and leaking out of the machine. This reduces fluid loss, minimizes environmental contamination risks, and eliminates a potential maintenance headache.
Q4: What approvals does the 330130-075-10-05 carry?
This cable is approved with CSA, ATEX, and IECEx certifications. These approvals confirm its suitability for installation in hazardous area classifications requiring explosion-proof instrumentation.
Q5: Can I use the silicone tape instead of purchasing a connector protector?
Yes, the silicone tape is included for this purpose. However, Bently Nevada strongly recommends against using silicone tape when the connection point will be exposed to turbine oil. For oil-exposed applications, use a dedicated connector protector for superior sealing and reliability.
