Bently Nevada 330130-080-12-CN Extension Cable 8m

Product Introduction

The Bently Nevada 330130-080-12-CN extension cable provides a reliable connection between your 3300 XL 8 mm probe and Proximitor Sensor. This 8.0-meter (26.2 feet) cable incorporates FluidLoc technology, which effectively blocks oil and other liquids from migrating through the cable interior. Consequently, this design prevents costly machine fluid leaks and protects sensitive measurement electronics. Additionally, the included connector protector eliminates the need for silicone tape in oil-exposed applications. First, the armored jacket shields the cable from mechanical damage. Next, the country-specific CN approval ensures compliance for projects in China and other regulated regions. Furthermore, this cable inherits all the advanced features of the 3300 XL series, including TipLoc and CableLoc technologies.

Technical Specifications for the 330130-080-12-CN

The Bently Nevada 330130-080-12-CN maintains rigorous electrical standards for precision proximity measurements. Specifically, the center conductor resistance (RCORE) measures 1.76 ± 0.26 Ω at 8.0 meters. Meanwhile, the outer conductor resistance (RJACKET) is 0.53 ± 0.11 Ω at the same length. Additionally, the cable shows a typical capacitance of 69.9 pF/m (21.3 pF/ft), ensuring consistent signal transmission across the full length.

For power supply, the Proximitor Sensor connected to this cable requires -17.5 Vdc to -26 Vdc under nonincendive circuit conditions. When utilizing barriers, the supply range adjusts to -23 Vdc to -26 Vdc. Moreover, the system consumption stays at 12 mA maximum. Supply sensitivity remains below 2 mV change per volt change, which preserves output stability. Therefore, you obtain dependable vibration and position data for effective condition monitoring programs.

FluidLoc Technology and Oil Protection

The Bently Nevada 330130-080-12-CN stands out with its FluidLoc cable option. This feature creates a positive seal that prevents oil and other process liquids from leaking out of the machine through the cable's interior. For turbine and compressor applications, oil ingress through standard cables poses a significant reliability risk. However, FluidLoc eliminates this concern entirely. Furthermore, this model comes with a connector protector, so you do not need to apply the silicone tape included with standard cables. In fact, we strongly advise against using silicone tape in turbine oil environments, as oil degrades silicone over time. Therefore, the 330130-080-12-CN offers a complete, ready-to-use solution for oil-lubricated machinery.

Environmental and Mechanical Durability

The armored construction of the Bently Nevada 330130-080-12-CN weighs 103 g/m (1.5 oz/ft), totaling 0.824 kg for the full 8.0-meter length. In comparison, the non-armored version weighs only 34 g/m (0.4 oz/ft) or 0.272 kg total. Thus, the armored version provides superior protection against crushing, abrasion, and impact damage. Additionally, the patented CableLoc design delivers 330 N (75 lbf) pull strength. This feature securely anchors the probe cable to the probe tip, preventing accidental disconnections during maintenance or vibration events.

The probe system also uses a Viton® O-ring to seal differential pressure between the probe tip and case. Although the factory does not pressure-test each unit, you can request custom testing for specific applications. Furthermore, humidity testing according to IEC 68-2-3 shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% relative humidity. Consequently, this cable performs reliably even in high-humidity environments common in tropical or coastal industrial sites.

Installation Guidelines for the 330130-080-12-CN

Proper installation of the Bently Nevada 330130-080-12-CN ensures optimal system performance. First, follow installation drawing 140979 for nonincendive circuit connections. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) tinned copper conductors. We recommend using 3-conductor shielded triad cable to minimize electrical noise interference. Additionally, the maximum field wiring distance between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). Be aware that longer wiring lengths affect high-frequency signal rolloff, so consult Figures 10 and 12 in the product manual for frequency response curves.

When connecting the probe to the 330130-080-12-CN, use the pre-installed connector protector instead of silicone tape. This connector protector offers better sealing and durability in oil environments. Moreover, set the probe gap at 1.25 mm to 1.30 mm (approximately 50 mils) to achieve the optimal linear range. The linear measurement range spans from 0.25 mm to 2.3 mm (10 to 90 mils), which produces an output of -1 to -17 Vdc.

Performance and System Compatibility

This extension cable is designed exclusively for 3300 XL 8 mm component systems. All performance specifications are validated using an AISI 4140 steel target at 18–27°C, with a -24 Vdc power supply and 10 kΩ load. Using non-standard target materials may reduce system accuracy and interchangeability. Therefore, always calibrate your system with Bently Nevada's recommended target material.

The patented TipLoc molding method ensures a durable bond between the probe tip and probe body. Similarly, CableLoc technology enhances pull strength to 330 N (75 lbf). Consequently, these design improvements extend service life and minimize measurement errors caused by loose connections. The FluidLoc feature adds an extra layer of protection, making the 330130-080-12-CN a superior choice for critical machinery monitoring.
