Bently Nevada 330930-045-01-00 3300 XL Extension Cable for Proximity Probes

This Bently Nevada extension cable connects proximity probes to Proximitor driver modules in monitoring systems. It extends the reach between the sensor and the monitoring electronics for flexible installation. Engineers can deploy this cable for turbine, compressor, and pump vibration monitoring applications. Its precision construction ensures reliable signal transmission over extended distances. The cable maintains system accuracy and performance in demanding industrial environments.

Physical Dimensions and Cable Construction

The cable measures 4.5 meters in length for versatile installation configurations. Its coaxial construction weighs approximately 0.4 pounds for straightforward routing. The unit features a 2.5 mm outer diameter for flexible cable management. A braided copper shield surrounds the inner conductor for noise immunity. This shielding prevents electromagnetic interference from adjacent electrical equipment.

Connector Specifications and Interface Details

The cable terminates with a standard 3-pin connector at each end. The sensor end connector mates directly with Bently Nevada proximity probes. The driver end connector interfaces with Proximitor driver modules securely. Both connectors include positive locking mechanisms for vibration-resistant connections. This design ensures reliable electrical contact throughout the monitoring system.

Electrical Characteristics and Signal Integrity

The cable exhibits a capacitance of 32 pF per foot for consistent signal transmission. Its impedance matches the 50 ohm requirement for proximity probe systems. The unit maintains signal integrity over the entire cable length without degradation. The inner conductor uses tinned copper for excellent conductivity and corrosion resistance. This construction ensures accurate probe measurements and system reliability.

Cable Jacket and Environmental Protection

The outer jacket utilizes FEP fluoropolymer material for chemical resistance. This jacket resists oil, water, and industrial solvents effectively. The cable operates reliably from -51 to 260 degrees Celsius ambient temperature. Its flame-retardant construction meets UL 910 standards for safety. The cable also resists abrasion and mechanical stress during installation.

System Compatibility and Integration

The cable works with all Bently Nevada 3300 XL proximity probes and drivers. It supports 5 mm, 8 mm, and 11 mm probe systems seamlessly. The unit also fits 3500 series monitoring system configurations. This compatibility simplifies spare parts management and system expansion. The cable maintains the factory calibration of the entire measurement chain.

Installation Flexibility and Routing Options

The cable allows installation distances up to 305 meters with proper driver selection. Its flexibility facilitates routing through conduit and cable trays easily. The unit includes a strain-relief boot at each connector for mechanical protection. This boot prevents cable fatigue from repeated bending and vibration. The cable supports both new installations and retrofit applications effectively.
