Bently Nevada 330130 Series Technical Notes

The Bently Nevada 330130 series comprises the standard proximity extension cables used throughout the 3300 XL and legacy 3300 machinery protection systems. These cables serve as the signal transmission link between the 3300 XL 8mm and 11mm proximity transducer probes and their paired Proximitor sensors. The 330130 series is installed across critical rotating machinery in petrochemical refineries, nuclear power stations, offshore platforms, LNG terminals, and heavy industrial compressor trains globally. Their function is deterministic: they extend the probe-to-Proximitor gap distance while maintaining the calibrated electrical characteristics required for accurate radial vibration, axial position, and speed measurement. Any deviation in cable impedance, shielding integrity, or connector termination directly affects the linear range and sensitivity of the overall measurement chain. For this reason, only OEM-specified or verified equivalent cables are accepted in safety-instrumented and API 670-compliant installations.

330130 Full Catalog & Functionalities (SKU List)

The following SKUs represent the verified 330130 proximity extension cable range, organized by cable length. Each part number encodes: series (330130), length in inches, connector type, and jacket specification.

330130-080-13-00: 80-inch standard proximity extension cable, coaxial, non-armored jacket, standard connectors — the most common field-replacement length for compressor and turbine installations.
330130-040-13-00: 40-inch extension cable for short probe-to-Proximitor runs in compact machinery housings.
330130-060-13-00: 60-inch extension cable, mid-range length for standard bearing housing configurations.
330130-100-13-00: 100-inch extension cable for extended routing paths in large turbine pedestals.
330130-120-13-00: 120-inch extension cable for installations requiring routing around structural obstructions.
330130-160-13-00: 160-inch extension cable for long-distance probe-to-Proximitor runs in large frame machines.
330130-200-13-00: 200-inch extension cable for extreme-length routing in power generation turbines.
330130-080-13-CN: 80-inch extension cable with armored (conduit-ready) outer jacket for high-vibration or high-temperature environments.
330130-040-13-CN: 40-inch armored extension cable for compact, high-vibration machinery.
330130-060-13-CN: 60-inch armored extension cable, conduit-compatible termination.
330130-100-13-CN: 100-inch armored extension cable for turbine applications requiring mechanical cable protection.
330130-080-00-00: 80-inch extension cable, alternate connector configuration for legacy 3300 (non-XL) Proximitor sensors.
330130-040-00-00: 40-inch extension cable for legacy 3300 series Proximitor sensors.
330130-060-00-00: 60-inch extension cable, legacy connector type, non-armored.
330130-100-00-00: 100-inch extension cable, legacy connector type, for older 3300 platform installations.
330130-160-00-00: 160-inch extension cable, legacy connector, for large-frame legacy machinery protection systems.
330130-200-00-00: 200-inch extension cable, legacy connector, for power plant turbine installations on pre-XL 3300 platforms.
