The 330130-045-12-05 extension cable is a precision-engineered component for Bently Nevada's 3300 XL 8 mm Proximitor monitoring systems. This cable links the proximity probe to the Proximitor sensor, enabling accurate vibration and position measurements on turbines, compressors, and other rotating equipment. Its 4.5‑meter length provides extended reach for installations where the sensor must be positioned farther from the probe. Additionally, this cable features FluidLoc technology, which effectively prevents oil and other liquids from leaking through the cable interior. The 330130-045-12-05 is therefore a trusted choice for critical machinery protection applications.
The 330130-045-12-05 features a FluidLoc cable with a connector protector, specifically designed to maintain seal integrity in oil-lubricated machinery. This design prevents liquid migration along the cable, protecting both the sensor and the monitoring system. The standard extension cable weighs 34 g/m (0.4 oz/ft), with a total weight of approximately 0.23 kg for the 4.5‑meter length. The cable construction incorporates flexible yet durable materials that withstand the rigors of industrial environments.
This extension cable maintains precise electrical properties essential for accurate proximity measurements. The nominal DC resistance from center conductor to center conductor (RCORE) is 0.99 ± 0.15 Ω. Meanwhile, the resistance from outer conductor to outer conductor (RJACKET) measures 0.30 ± 0.06 Ω. Furthermore, the cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. These specifications ensure consistent system performance when paired with 3300 XL Proximitor sensors, delivering reliable data for machinery protection systems.
The 330130-045-12-05 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 where explosive atmospheres may exist. The 05 approval code indicates full compliance with these stringent international standards.
Manufactured in the U.S.A., this cable meets Bently Nevada's rigorous quality standards. It operates effectively between +18°C and +27°C (+64°F to +80°F) at a maximum altitude of 2000 meters. The probe features patented TipLoc molding, creating a robust bond between the probe tip and body that resists mechanical stress. Additionally, the CableLoc design provides 330 N (75 lbf) pull strength, ensuring the probe cable and tip remain securely attached even under vibration or accidental tension. The probe sealing material consists of a Viton® O‑ring, which seals differential pressure between the probe tip and case.
When used with 3300 XL 8 mm components, the 330130-045-12-05 delivers reliable monitoring performance. The linear range spans 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, providing a clear signal proportional to the gap. The power supply requirement is -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Operation at voltages more positive than -23.5 Vdc may reduce the linear range, so careful power supply selection is important. The output resistance is 50 Ω, while supply sensitivity remains below 2 mV change per volt change in input voltage.
This cable system demonstrates exceptional environmental resilience. Specifically, the Average Scale Factor (ASF) changes by less than 3% when tested in 93% humidity for up to 56 days, in accordance with IEC standard 68‑2‑3. This performance ensures stable, accurate measurements even in humid or harsh operating conditions commonly found in coastal facilities or tropical environments.
For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) 3‑conductor shielded triad cable with tinned wiring. The maximum field wiring length is 305 meters (1,000 feet) between the Proximitor sensor and the monitor. Consult the frequency response graphs in the product documentation to understand signal rolloff at high frequencies when using longer wiring lengths. Proper shielding and grounding practices are essential for maintaining signal integrity.
Installing the 330130-045-12-05 extension cable requires careful attention to best practices. First, always power down the monitoring system before connecting or disconnecting any cables. Next, attach the extension cable to the 3300 XL 8 mm probe using the FluidLoc connector, ensuring it is fully seated. Then, connect the opposite end to the Proximitor sensor, following the manufacturer's torque specifications.
Each 3300 XL extension cable includes silicone tape as an alternative to connector protectors. However, do not use silicone tape where the probe‑to‑extension cable connection will be exposed to turbine oil, as this may compromise the seal. For applications requiring pressure seal testing, contact Bently Nevada's custom design department directly. Probes are not pressure tested prior to shipment, so this step is essential for critical or high‑risk installations.
