The Bently Nevada 330730-080-10-00 is a high-performance extension cable from the renowned 3300 XL series. This model measures 8.0 meters (26.2 feet) in length. It connects the 3300 XL 11 mm probe to the Proximitor Sensor for vibration monitoring. The key feature of this version is the FluidLoc cable option (code 10). This design prevents oil and other process liquids from leaking out of the machine through the cable's interior. Therefore, it is ideal for turbine and compressor applications where oil exposure is a concern.
This cable uses a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. The FEP material offers excellent dielectric properties and chemical resistance. Its gold-plated brass ClickLoc connectors lock securely into place. This locking mechanism prevents loosening due to vibration. Additionally, the connectors resist corrosion for long-term reliability. The 330730-080-10-00 maintains a typical capacitance of 69.9 pF/m (21.3 pF/ft). This low capacitance preserves signal quality over the full 8.0-meter length.
The FluidLoc option sets this extension cable apart from standard models. FluidLoc creates a positive seal within the cable assembly. Consequently, it stops oil from migrating along the cable interior and escaping the machine casing. This feature is especially valuable in high-pressure turbine environments. It also reduces the risk of environmental contamination and safety hazards.
Furthermore, this cable includes connector protectors for additional moisture resistance. However, silicone tape is also provided with each extension cable. You can use silicone tape as an alternative to connector protectors. But remember, silicone tape is not recommended when the connection will be exposed to turbine oil. Therefore, for oil-exposed applications, we strongly recommend using the connector protectors instead.
The 3300 XL 11 mm probe comes standard with a locknut featuring pre-drilled safety wire holes. This locknut ensures the probe stays securely mounted even under severe vibration. All transducer system components share the same gold-plated ClickLoc connectors. This standardization simplifies installation and maintenance across your entire monitoring system.
The Bently Nevada 330730-080-10-00 delivers consistent electrical performance over its 8.0-meter length. The DC resistance from center conductor to center conductor (RCORE) is 2.0 ± 0.5 ohms. The resistance from coaxial conductor to coaxial conductor (RJACKET) measures 0.6 ± 0.2 ohms. These values ensure proper impedance matching with the 3300 XL Proximitor Sensor.
For field wiring, this cable accepts conductors from 0.2 to 1.5 mm² (16 to 24 AWG). We recommend using a three-conductor shielded triad cable for optimal noise rejection. The maximum field wiring length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, check the frequency response graph for signal rolloff at extended lengths.
When combined with the 3300 XL probe, the system's linear range spans 4.0 mm (160 mils). The linear range starts at approximately 0.5 mm (20 mils) from the target. It then extends from 0.5 to 4.5 mm (20 to 180 mils), corresponding to -1 to -17 Vdc. The recommended gap setting is 2.5 mm (100 mils) for optimal linearity. The incremental scale factor (ISF) is 3.94 V/mm (100 mV/mil) with ±10% interchangeability error.
This extension cable offers a wide operating temperature range of -51°C to +177°C (-60°F to +351°F). For storage, the range extends slightly to -52°C to +177°C (-62°F to +351°F). Therefore, it performs reliably in extreme industrial environments. The optional flexible AISI 302 SST armor with FEP outer jacket provides extra mechanical protection.
The armored version weighs 140 g/m (1.5 oz/ft), totaling 1.12 kg for the 8.0-meter length. The unarmored version weighs only 45 g/m (0.5 oz/ft), totaling 0.36 kg. Choose the armored option for installations where abrasion or impact is a concern. The probe tip material is polyphenylene sulfide (PPS), which offers excellent wear resistance. The probe case uses AISI 304 stainless steel for corrosion resistance.
Bently Nevada's patented TipLoc molding method ensures a robust bond between the probe tip and body. Meanwhile, the CableLoc design securely attaches the cable to the probe tip. This provides 330 N (75 lb) pull strength for reliable connections. All these features make the 330730-080-10-00 a durable choice for critical machinery protection.
Proper installation ensures accurate measurements and long service life. First, verify that the 8.0-meter length suits your system requirements. This cable works within 5 or 9-meter total system lengths. Next, connect the cable securely to both the probe and the Proximitor Sensor. Ensure the ClickLoc connectors are fully engaged and locked.
Set the probe gap to the recommended 2.5 mm (100 mils) for optimal performance. Use the ISF of 3.94 V/mm (100 mV/mil) for calibration. Remember that the extended DSL range (0.5 to 5.0 mm / -1 to -19 Vdc) is not applicable with zener barriers. When routing the cable, avoid sharp bends and excessive strain. The tensile strength limits are 330 N for the probe case and 270 N for the connectors.
For FluidLoc installations, ensure the cable seal is properly engaged at both ends. This prevents any oil or liquid leakage through the cable interior. If you operate in a humid environment, install the connector protectors for added moisture resistance. For armored cables, ensure the armor does not contact live electrical parts.
Your order for the 330730-080-10-00 includes the extension cable with FluidLoc feature. Each unit is individually packaged to prevent damage during transit. We ship exclusively via FedEx, UPS, or DHL for fast, reliable delivery. All shipments are fully trackable and insured.

Q1: What does the FluidLoc option do for this extension cable?
The FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable's interior. This makes the Bently Nevada 330730-080-10-00 ideal for turbine and compressor applications with oil exposure.
Q2: Can I use silicone tape instead of connector protectors?
Yes, silicone tape is provided with each extension cable. However, do not use silicone tape in applications where the connection will be exposed to turbine oil. Use the connector protectors instead for those environments.
Q3: What is the total system length when using this 8.0-meter cable?
The 3300 XL 11 mm extension cable combines with the probe to form a total system length of either 5 or 9 meters. The 8.0-meter cable is typically used in the 9-meter system configuration.
Q4: What is the difference between armored and unarmored versions?
The armored version adds a flexible AISI 302 SST layer with FEP outer jacket. It provides extra protection against abrasion and impact. The unarmored version is lighter and more flexible for easier routing.
Q5: Is this cable compatible with other target materials besides AISI 4140 steel?
Proximitor Sensors are factory calibrated to AISI 4140 steel by default. Calibration to other target materials is available upon request. Please specify your target material when ordering if different from the default.
