330130-040-01-05 Bently Nevada Heavy Duty Armored Cable

Product Overview

The Bently Nevada 330130-040-01-05 operates as a high-performance 3300 XL series extension cable engineered for proximity transducer systems[cite: 1]. This premium 4.0-meter armored cable acts as the vital electrical link connecting an 8 mm eddy current probe to a Proximitor Sensor[cite: 1]. It accurately transmits high-frequency displacement telemetry from critical rotating machinery, such as industrial steam turbines and compressors, without signal degradation or impedance mismatches[cite: 1]. Featuring a robust total net weight of 0.618 kg, this USA-made product ensures optimal protection and long-term reliability in severe industrial settings[cite: 1]. For international supply chain compliance, an official Certificate of Origin (COO) can be added upon request[cite: 1].

Core Technological Advantages

Suffix Part-Number Configuration

The specific model code string outlines precise structural properties engineered for immediate deployment[cite: 1]:

• 040 Cable Length Option: Provides a nominal cable length of exactly 4.0 meters (11.5 feet) for specific sensor-to-amplifier distances[cite: 1].
• 01 Connector Option: Features a rugged, heavy-duty armored cable configuration designed to withstand mechanical impacts[cite: 1].
• 05 Approvals Option: Includes full hazardous area certifications complying with global CSA, ATEX, and IECEx safety frameworks[cite: 1].

Heavy-Duty Armoring and Pull Strength

The physical build features a standard armored jacket layout, optimized at a density of 103 g/m to achieve its solid 0.618 kg total weight[cite: 1]. The underlying architecture utilizes a patented CableLoc design, delivering a massive 330 N (75 lbf) pull strength to ensure the assembly securely attaches and withstands severe industrial pulling tension[cite: 1].

Precision DC Electrical Resistance

The cable core establishes highly repeatable eddy current sensor calibrations through strictly controlled internal resistance tolerances[cite: 1]. The center conductor (RCORE) maintains a low resistance of 0.88 ± 0.13 Ω, while the outer jacket boundary (RJACKET) measures precisely 0.26 ± 0.05 Ω[cite: 1].

Technical Specifications

Engineering Installation Guide

Probe Connection and Oil Protection

Each cable kit includes premium silicone tape[cite: 1]. However, do not apply silicone tape if the active probe-to-extension connection faces exposure to aggressive turbine oil[cite: 1]. For these specific applications, alternative connector protection housings should be sourced to safeguard the electrical interface from oil ingress[cite: 1].

Standard Operational Gap Reference

For nominal calibration and maximum measurement linearity across the 2 mm span, gap the 8 mm eddy current probe exactly at 1.27 mm (50 mils) from the target[cite: 1]. Ensure the machine shaft target consists of AISI 4140 steel to maintain strict loop output accuracy[cite: 1].

Field Wiring Configurations

Connect the Proximitor Sensor to monitors using a 3-conductor shielded triad cable with tinned wiring[cite: 1]. Keep the total wire run below the maximum physical limit of 305 meters (1,000 feet) to prevent signal roll-off at elevated machine vibration frequencies[cite: 1]. Properly anchor the 0.618 kg armored assembly to prevent tension on the probe connection points[cite: 1].

Engineering Advantages

Premium Protection and Signal Integrity

The dynamic uncompromised design matches low nominal line capacitance with an output resistance of 50 Ω[cite: 1]. The outer armoring adds extreme crush protection without compromising the high-fidelity loop frequency response[cite: 1].

Excellent Humidity Stability

Tested in strict compliance with the IEC 68-2-3 standard for 56 continuous days inside 93% relative humidity chambers, the internal materials demonstrate under a 3% change in Average Scale Factor (ASF)[cite: 1].

Patented Structural Durability

Combining the proprietary TipLoc body molding with the CableLoc termination method secures components against a pull force up to 330 N, eliminating standard cable detachment errors inside harsh machinery housings[cite: 1].

Technical FAQs

Q1: What happens if the system input supply voltage rises more positive than -23.5 Vdc?
A1: Operating the transducer system with a power level more positive than -23.5 Vdc can degrade performance, leading to a significantly reduced linear range across the AISI 4140 steel target[cite: 1].

Q2: What is the physical weight specification of this armored extension cable?
A2: This 4.0-meter armored version has a unit density of 103 g/m, yielding a total net weight of 0.618 kg[cite: 1]. This construction provides superior mechanical crush protection compared to unarmored 0.204 kg variants[cite: 1].

Q3: Why are the core conductor and jacket resistances of this 4.0m cable controlled so tightly?
A3: RCORE (0.88 ± 0.13 Ω) and RJACKET (0.26 ± 0.05 Ω) are strictly tuned to ensure complete interchangeability with standard 3300 XL Proximitors without requiring a complete hardware recalibration[cite: 1].
