The 330130-040-12-05 extension cable is a critical component for Bently Nevada's 3300 XL 8 mm Proximitor monitoring systems. This cable connects the proximity probe to the Proximitor sensor, enabling accurate vibration and position measurements on rotating machinery. Its 4.0‑meter length provides flexibility for installation in various machine configurations. Additionally, this cable incorporates advanced design features that enhance reliability in demanding industrial environments.
The 330130-040-12-05 features a FluidLoc cable with a connector protector. This design prevents oil and other liquids from leaking out of the machine through the cable interior. The cable is available in both standard and armored versions. The standard extension cable weighs 34 g/m (0.4 oz/ft), while the armored version weighs 103 g/m (1.5 oz/ft).
This extension cable maintains precise electrical properties for accurate signal transmission. The nominal DC resistance from center conductor to center conductor (RCORE) is 0.88 ± 0.13 Ω. Meanwhile, the resistance from outer conductor to outer conductor (RJACKET) measures 0.26 ± 0.05 Ω. Furthermore, the cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. These specifications ensure consistent performance with 3300 XL Proximitor sensors.
The 330130-040-12-05 carries multiple approvals for global use. Specifically, it holds CSA, ATEX, and IECEx certifications for hazardous area installations. These approvals confirm its suitability for Class I, Division 2, and Zone 2 locations. Consequently, this cable is an excellent choice for oil and gas, petrochemical, and power generation facilities.
The cable is manufactured in the U.S.A. and meets strict quality standards. It operates effectively in temperatures from +18°C to +27°C (+64°F to +80°F) at a maximum altitude of 2000 meters. The probe features a patented TipLoc molding method that provides a robust bond between the probe tip and body. Additionally, the CableLoc design offers 330 N (75 lbf) pull strength, ensuring secure attachment of the probe cable and tip.
When used as part of a complete 3300 XL 8 mm system, the 330130-040-12-05 delivers reliable performance. The linear range is 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target. Output voltage ranges from –1 to –17 Vdc over this linear range. The power supply requirement is -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Additionally, the output resistance is 50 Ω, and supply sensitivity is less than 2 mV change per volt change in input voltage.
Installing the 330130-040-12-05 extension cable requires careful attention to detail. First, ensure the system is powered down before connecting or disconnecting the cable. Next, attach the extension cable to the 3300 XL 8 mm probe using the FluidLoc connector. Then, connect the other end to the Proximitor sensor. Importantly, ensure all connections are clean and dry to maintain signal integrity. The included silicone tape can be used instead of connector protectors for some applications. However, silicone tape is not recommended where the probe-to-extension cable connection will be exposed to turbine oil.
For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) 3‑conductor shielded triad cable with tinned wiring. Maximum field wiring length is 305 meters (1,000 feet) between the sensor and monitor. Always refer to the frequency response graphs for signal rolloff considerations when using longer wiring lengths.

1. What is the primary purpose of the Bently Nevada 330130-040-12-05 cable?
This cable connects 3300 XL 8 mm proximity probes to Proximitor sensors for vibration and position monitoring on rotating machinery.
2. Is the 330130-040-12-05 suitable for hazardous locations?
Yes, it carries CSA, ATEX, and IECEx approvals for Class I, Division 2, and Zone 2 hazardous areas.
3. Can I use silicone tape instead of the connector protector?
Silicone tape is included and can be used for many applications. However, do not use it where the connection will be exposed to turbine oil.
4. What is the difference between standard and armored extension cables?
The armored version weighs 103 g/m compared to 34 g/m for the standard cable. Armored cables provide additional mechanical protection.
5. How should I handle the probe pressure sealing requirement?
3300 XL 8 mm probes are designed to seal differential pressure using a Viton O-ring. Contact Bently Nevada's custom design department if pressure seal testing is required.
