Bently Nevada 330190-045-01-00 3300 XL ETR Extension Cable

Product Overview

A rugged extension cable arrives as the 330190-045-01-00 from Bently Nevada. This cable belongs to the 3300 XL Extended Temperature Range (ETR) product family. The 330190-045-01-00 measures exactly 4.5 meters (14.8 feet) in total length. Engineers use this cable to connect 3300 XL proximity probes to Proximitor sensors. Consequently, the 330190-045-01-00 suits applications with extreme temperature requirements. PFA insulation allows operation up to +260°C, far beyond standard cable limits.

Ordering Information Breakdown

The model number 330190-045-01-00 follows a clear breakdown structure. First, 330190 identifies the base extension cable model number. Second, the -045 option specifies 4.5 meters (14.8 feet) of cable length. Third, the -01 option indicates armored cable construction for physical protection. Finally, the -00 option means no agency approval is required for this order. Thus, the 330190-045-01-00 provides a rugged, extended temperature solution.

Electrical Specifications

The 330190-045-01-00 uses 75Ω triaxial construction for signal integrity. Standard cable uses fluoroethylene propylene (FEP) insulation material. However, this ETR version uses perfluoroalkoxy (PFA) insulation instead. PFA withstands significantly higher temperatures than standard FEP insulation. Consequently, the 330190-045-01-00 operates reliably in extremely hot environments.

Nominal DC resistance from center conductor to center conductor:

Nominal DC resistance from outer conductor to outer conductor:

Capacitance: 69.9 pF/m (21.3 pF/ft) typical.

Linear Range and Gap Settings

The 330190-045-01-00 works within a precise linear measurement range. Total linear range spans 2 mm (80 mils) from target surface. Linear range begins at approximately 0.25 mm (10 mils) from the target. The full linear zone extends from 0.25 to 2.3 mm (10 to 90 mils). This range corresponds to approximately -1 to -17 Vdc output signal.

For radial vibration measurements, the recommended gap setting is -9 Vdc. This voltage corresponds to approximately 1.27 mm (50 mils) from the target. Therefore, always set your probe gap to -9 Vdc when using the 330190-045-01-00 with 3300 XL systems.

Physical Specifications

Temperature Range and Environmental Tolerance

The 330190-045-01-00 excels in extreme temperature environments. Operating and storage temperature spans -52°C to +260°C (-62°F to +500°F). This range far exceeds standard cable specifications due to PFA insulation. For comparison, standard FEP cables only reach +177°C maximum. Thus, the 330190-045-01-00 suits gas turbines, furnaces, and other high-heat applications.

Minimum cable bend radius measures 25.4 mm (1.0 inch) for this cable. Exceeding this bend radius may damage internal conductors or insulation. Therefore, plan your cable routing carefully to avoid tight bends. The armored construction (-01 option) protects against physical damage in rough environments. Consequently, the 330190-045-01-00 survives impacts and abrasion better than standard cables.

Field Wiring Guidelines

Proper field wiring ensures optimal performance from the 330190-045-01-00. Use 0.2 to 1.5 mm² (16 to 24 AWG) wire for field connections. Bently Nevada recommends using 3-conductor shielded triad cable for best results. Additionally, use tinned field wiring to prevent corrosion over time.

Maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, longer field wiring lengths cause signal rolloff at high frequencies. Consult the frequency response graphs (Figures 10 and 12) for specific attenuation data. For high-frequency applications, keep field wiring as short as possible.

Connector Details

The 330190-045-01-00 uses high-quality connectors for reliable connections. Connector material consists of gold-plated brass or gold-plated beryllium copper. Gold plating prevents corrosion and ensures low contact resistance over time. Maximum connector torque is 0.565 N•m (5 in•lbf) to prevent damage.

Do not overtighten connectors on the 330190-045-01-00. Excessive torque may strip threads or damage connector internals. Use a torque wrench for consistent, safe tightening each time. The armored cable option includes a durable locking ring for secure attachment.

Compatibility Information

The 330190-045-01-00 works with several 3300 XL components. 3300 XL 8 mm components are electrically and physically interchangeable. This interchangeability applies to both XL and non-XL 3300 components. However, always observe the minimum permissible cable bend radius of 25.4 mm. Non-XL 3300 5 mm and 8 mm components also work with this cable.

Do not use the 330190-045-01-00 with incompatible probe models. Always verify compatibility before connecting to your specific system. The extended temperature range requires matching components for full benefit. Therefore, ensure your probes and Proximitor sensors also support ETR ratings.

Compliance and Certifications

The 330190-045-01-00 carries multiple important certifications. FCC compliance under part 15 ensures electromagnetic compatibility in the United States. Operation is subject to two conditions: no harmful interference and acceptance of received interference.

EMC compliance follows European Community Directive 2014/30/EU. Standards include EN 61000-6-2 (Immunity for Industrial Environments). Additionally, EN 61000-6-4 (Emissions for Industrial Environments) applies. RoHS compliance follows European Directive 2011/65/EU for hazardous substance restrictions.

Maritime certification meets 2019 Rules for Conditions of Classification. Applicable sections include Part 1, 1-1-1/7.7, 1-1-A3, and 1-1-A4. Offshore unit compliance includes Part 1, 1-1-4/9.7, 1-1-A2, and 1-1-A3.

Functional safety ratings include SIL 2 with HFT = 0. For higher reliability, SIL 3 is achievable with HFT = 1. Thus, the 330190-045-01-00 suits safety-critical machinery protection applications.

Signal Integrity and Performance

The 330190-045-01-00 maintains signal quality across its 4.5 meter length. Capacitance measures 69.9 pF/m typical, which preserves high-frequency response. Low capacitance minimizes signal rolloff even at extended lengths. The 75Ω triaxial construction matches standard 3300 XL system impedance perfectly.

DC resistance from center conductor to center conductor is 0.99 ± 0.15 Ω. Outer conductor resistance measures 0.30 ± 0.06 Ω for the same length. Low resistance ensures minimal voltage drop across the extension cable. Consequently, the 330190-045-01-00 preserves measurement sensitivity and linearity accurately.

Frequency response remains flat within the standard proximity probe range. For most machinery monitoring below 10 kHz, no meaningful attenuation occurs. However, refer to the frequency response graphs for high-frequency applications. The environmental tolerance of PFA insulation enables reliable operation in extreme heat.

Installation Guide

Frequently Asked Questions (FAQ)

1. What is the difference between the 330190-045-01-00 and standard extension cables?

The 330190-045-01-00 uses PFA insulation instead of standard FEP material. PFA withstands +260°C, whereas FEP only reaches +177°C maximum. Additionally, the -01 option adds armor for physical protection against impacts and abrasion.

2. Can I use the 330190-045-01-00 with non-3300 XL probes?

The 330190-045-01-00 is designed specifically for 3300 XL system compatibility. However, it works with non-XL 3300 5 mm and 8 mm components as well. Always verify electrical compatibility before connecting to other probe families.

3. What happens if I exceed the minimum bend radius of 25.4 mm?

Exceeding 25.4 mm bend radius may damage internal conductors or insulation. Signal degradation, intermittent connections, or complete cable failure can result. Therefore, always plan your cable route to avoid tight bends with the 330190-045-01-00.

4. Is the 330190-045-01-00 suitable for underwater or submerged applications?

The 330190-045-01-00 has splash resistance but is not designed for continuous submersion. For underwater applications, additional sealing and protection would be necessary. Consult Bently Nevada for special submersible cable options if needed.

5. How do I verify correct installation of the 330190-045-01-00?

Measure DC resistance from center conductor to center conductor after installation. Expected value for 4.5 meters is 0.99 ± 0.15 Ω. Additionally, measure outer conductor resistance expecting 0.30 ± 0.06 Ω. Values outside these ranges indicate possible connector or cable damage.
