Bently Nevada 330130-075-12-05 7.5m Extension Cable

Bently Nevada 330130-075-12-05 Extension Cable for 3300 XL Monitoring Systems

Product Introduction

The Bently Nevada 330130-075-12-05 is a premium extension cable designed for use with 3300 XL series Proximitor sensors and proximity probes. This 7.5-meter (24.6 feet) cable incorporates the advanced FluidLoc feature, which effectively blocks oil and other liquids from migrating through the cable's interior. Additionally, this specific model includes a connector protector for enhanced connection security. Its gold-plated ClickLoc connectors offer outstanding corrosion resistance and maintain signal integrity over time. Furthermore, the Bently Nevada 330130-075-12-05 carries ATEX, CSA, and IECEx approvals, making it fully suitable for installation in potentially explosive environments. Choose this cable to ensure accurate vibration data and long-term reliability for your machinery protection system.

Technical Specifications

The Bently Nevada 330130-075-12-05 exhibits precise electrical characteristics that guarantee measurement accuracy. For example, its typical capacitance is rated at 69.9 pF/m (21.3 pF/ft). The nominal DC resistance from center conductor to center conductor (RCORE) measures 1.65 ± 0.25 Ω, while the outer conductor resistance (RJACKET) is 0.49 ± 0.10 Ω for this 7.5-meter length. This cable is fully compatible with the 3300 XL Proximitor sensor, which requires a power supply of -17.5 Vdc to -26 Vdc (or -23 Vdc to -26 Vdc with barriers). Additionally, the system offers a supply sensitivity of under 2 mV per volt change and a 50 Ω output resistance. Its linear range spans 2 mm (80 mils) for effective displacement measurement.

Mechanical and Environmental Durability

Industrial environments demand rugged components, and the Bently Nevada 330130-075-12-05 delivers on this requirement. It features a patented CableLoc design that provides a pull strength of 330 N (75 lbf) for secure attachment between the cable and probe tip. Likewise, the TipLoc molding method significantly strengthens the bond between the probe tip and its body. The FluidLoc option is particularly valuable for turbine applications, as it stops oil from leaking out through the cable's interior. Moreover, the connector protector supplied with this model adds an extra layer of defense against contamination. All connectors are gold-plated to resist corrosion and ensure a stable, low-resistance connection throughout the cable's service life.

Approvals and System Compatibility

The Bently Nevada 330130-075-12-05 meets stringent international safety standards. Specifically, it holds CSA, ATEX, and IECEx approvals, confirming its suitability for use in explosive atmospheres. This extension cable works with non-contacting 3300-series 5 mm probes, 3300 8 mm probes, and 3300 XL 8 mm probes. Nevertheless, to achieve the specified system accuracy and interchangeability, Bently Nevada recommends using it exclusively with 3300 XL 8 mm components and calibrating against an AISI 4140 steel target. For field wiring, we recommend using 3-conductor shielded triad cable (16 to 24 AWG). The maximum recommended distance between the Proximitor sensor and the monitor is 305 meters (1,000 feet), with frequency response graphs available for reference when using longer runs.

Installation Guidelines

Correct installation is crucial for maximizing the performance of the Bently Nevada 330130-075-12-05. First, always utilize the gold-plated ClickLoc connectors to ensure a secure and corrosion-resistant connection. This model includes a connector protector, which offers superior protection compared to the silicone tape included with standard cables. In fact, Bently Nevada advises against using silicone tape in applications where the connection point may be exposed to turbine oil. Therefore, the connector protector is the recommended solution for such harsh conditions. Additionally, verify the power supply voltage is set correctly, particularly when using barriers, to avoid operating at a voltage more positive than -23.5 Vdc, which could reduce the linear range. The associated 3300 XL 8 mm probes feature a Viton® O-ring to seal differential pressure between the probe tip and case.
