Bently Nevada 330130-040-00-00 3300XL Proximity Probe Extension Cable Product Specification
330130-040-00-00 is factory pre-calibrated extension cable belonging to Bently Nevada classic 3300XL eddy current sensor system. It acts as intermediate signal transmission component to connect 3300XL proximity probe and matching proximitor transducer, forming a complete closed-loop measurement system for non-contact online monitoring of radial shaft vibration, axial thrust displacement and Keyphasor rotational speed of critical rotating machinery including steam turbines, centrifugal compressors, feed pumps, blowers and generator units in power, petrochemical and metallurgical industries. Each finished cable undergoes factory capacitance matching test, continuity inspection and connector sealing test before delivery to ensure stable dielectric property and consistent measuring accuracy under complicated industrial electromagnetic and temperature conditions. New original cables follow US production specifications with standard factory warranty, while qualified refurbished cables complete full electrical recalibration and sealing recheck for equipment maintenance replacement.

Bently Nevada 330130-040-00-00 3300XL Proximity Probe Extension Cable Product Specification
1. Product Overview
330130-040-00-00 is factory pre-calibrated extension cable belonging to Bently Nevada classic 3300XL eddy current sensor system. It acts as intermediate signal transmission component to connect 3300XL proximity probe and matching proximitor transducer, forming a complete closed-loop measurement system for non-contact online monitoring of radial shaft vibration, axial thrust displacement and Keyphasor rotational speed of critical rotating machinery including steam turbines, centrifugal compressors, feed pumps, blowers and generator units in power, petrochemical and metallurgical industries. Each finished cable undergoes factory capacitance matching test, continuity inspection and connector sealing test before delivery to ensure stable dielectric property and consistent measuring accuracy under complicated industrial electromagnetic and temperature conditions. New original cables follow US production specifications with standard factory warranty, while qualified refurbished cables complete full electrical recalibration and sealing recheck for equipment maintenance replacement.
2. Part Number Coding Definition
The four-section part number follows standard Bently product coding rules:330130 stands for core series code of standard extension cable designed exclusively for 3300XL proximity sensor system, whose internal dielectric and conductor structure are customized to fix capacitance parameters required for eddy current measurement loop.040 defines factory locked total calibrated electrical length at 4.0 meters; this length is included in overall system capacitance calculation together with probe body, any replacement with different-length cable will break original impedance matching and lead to measurement nonlinear drift.The first 00 indicates standard non-armored outer sheath configuration without metal protective armor layer, adopting factory standard insulation outer casing design.The trailing 00 represents default standard stainless steel threaded connectors equipped at both cable ends, no customized modified plug or special terminal layout is applied. All coded specifications are fixed upon production and cannot be altered arbitrarily on site.
3. Material and Mechanical Specifications
Inner conductor is constructed with high-purity multi-strand oxygen-free copper to lower high-frequency signal attenuation and improve anti-interference performance during signal transmission. Intermediate insulation layer uses stable fluoropolymer material with consistent dielectric constant, excellent oil resistance and high-low temperature resistance to keep fixed capacitance unchanged under fluctuating ambient conditions. Outer protective jacket is made of wear-resistant thermoplastic elastomer, effectively resisting mechanical scratch, lubricating oil splash and workshop dust erosion. Both terminals are precision machined stainless steel threaded connectors fitted with built-in rubber sealing rings to prevent moisture, oil mist and fine metal powder penetrating into wiring junction. The cable retains appropriate flexible bending performance to facilitate field wiring along equipment casing and cable trough without insulation cracking under regular installation bending radius.
4. Electrical Matching and Environmental Working Requirements
This extension cable is matched with standard 3300XL proximity probe and corresponding 330180 series proximitor powered by -17.5VDC ~ -26VDC negative DC supply. The complete measurement loop maintains factory-set standard sensitivity of 7.87V/mm, with frequency response ranging from 0Hz to 10kHz to cover slow static axial displacement and high-frequency dynamic rotor vibration detection.
Permitted continuous operating ambient temperature ranges from -40℃ to +125℃, suitable for low-temperature outdoor installation and high-temperature layout near hot-running equipment casing; storage temperature spans -55℃ to +95℃ under dry non-condensing environment. Applicable working relative humidity is limited between 5%RH and 95%RH with no internal condensation allowed to avoid insulation degradation and inner core short circuit. For installation altitude over 1000 meters, shorten regular inspection cycle appropriately due to changed atmospheric environment. The cable withstands industrial vibration of 10Hz~60Hz; long-term usage in surroundings with strong corrosive gas, dense chemical vapor and accumulated conductive metal dust is forbidden to extend service life.
5. Application Scope and Routine Maintenance Guidance
330130-040-00-00 extension cables are widely used for TSI protection system configuration of large rotating equipment across thermal power, petrochemical and metallurgical fields, transmitting clearance signal from mounted probe to proximitor for subsequent data processing by Bently 3500 monitoring rack or field DCS/PLC to realize equipment over-limit alarm and emergency trip interlock protection.
During daily maintenance, regularly check outer jacket integrity and connector fastening condition to prevent signal intermittent failure caused by loose connection or casing breakage and oil infiltration. For breakdown replacement, only same full part number 4-meter calibrated extension cable can be used; mismatched length will change overall loop capacitance and result in zero drift or invalid monitoring data. All aftermarket refurbished cables pass capacitance testing, no-load reciprocating aging and temperature cycling inspection per original factory standards before delivery to keep performance consistent with original new products.
