330190-075-01-05 Bently Nevada Armored Extension Cable

Product Introduction

The Bently Nevada 330190-075-01-05 is a specialized extension cable from the 3300 XL series, designed for demanding applications where safety certifications are mandatory. This model carries the Agency Approval Option 05, which includes CSA, ATEX, and IECEx certifications for use in hazardous locations. The 330190-075-01-05 features an armored construction that provides superior mechanical protection against physical damage. Its extended temperature range capability makes it suitable for both onshore and offshore installations where extreme heat or cold is a concern. This cable ensures reliable signal transmission between the 3300 XL Proximitor Sensor and the monitoring system.

Technical Specifications of the 330190-075-01-05

The 330190-075-01-05 offers consistent and precise electrical characteristics. The nominal DC resistance from the center conductor to center conductor (RCORE) is 1.65 ± 0.25 Ω. Meanwhile, the resistance from the outer conductor to outer conductor (RJACKET) is 0.49 ± 0.10 Ω. Additionally, the typical capacitance measures 69.9 pF/m (21.3 pF/ft). These parameters ensure accurate data transmission across the 7.5-meter cable length. The connector uses gold-plated brass or beryllium copper materials for excellent conductivity. Furthermore, the maximum connector torque is 0.565 N•m (5 in•lbf), which must be strictly observed during installation.

Hazardous Area Certifications

A key differentiator for the 330190-075-01-05 is its comprehensive certification suite. This model holds CSA (Canadian Standards Association), ATEX (European Directive for explosive atmospheres), and IECEx (International Electrotechnical Commission) approvals. These certifications allow the 3300 XL ETR cable to be installed in Zone 1, Zone 2, and other classified hazardous areas. Consequently, this makes the 330190-075-01-05 the preferred choice for oil refineries, chemical plants, and gas processing facilities. The certifications are clearly marked on the cable for easy identification during audits.

Mechanical and Environmental Parameters

The 330190-075-01-05 operates reliably across a wide temperature spectrum. It functions and stores safely between -52°C and +260°C (-62°F to +500°F). This extended range is achieved through PFA (perfluoroalkoxy) insulation, which outperforms standard FEP insulation. The armored version of this extension cable weighs approximately 103 g/m (1.5 oz/ft), providing substantial mechanical resilience. Moreover, the cable has a minimum bend radius of 25.4 mm (1.0 inch), which must be maintained during routing to prevent internal conductor damage.

Compliance and Standards

Beyond hazardous area certifications, the 330190-075-01-05 meets multiple international standards. It complies with FCC Part 15 rules and adheres to the EMC Directive 2014/30/EU, including EN 61000-6-2 and EN 61000-6-4. Additionally, it is RoHS compliant with Directive 2011/65/EU. For maritime applications, it meets the 2019 Rules for Conditions of Classification for both ships and offshore units. For functional safety, the 3300 XL ETR cable supports SIL 2 (HFT = 0) and SIL 3 (HFT = 1) rated systems.

Installation Guidelines for the 330190-075-01-05

Proper installation of the 330190-075-01-05 is critical to maintain its certified safety integrity. First, always respect the minimum bend radius of 25.4 mm (1.0 inch) to avoid stressing the triaxial conductors. Second, apply the recommended connector torque of 0.565 N•m (5 in•lbf) – over-tightening can damage the gold-plated connector. For field wiring, use a 3-conductor shielded triad cable with 16 to 24 AWG tinned conductors. The maximum field wiring length between the Proximitor sensor and the monitor is 305 meters (1,000 feet). Additionally, check the frequency response graphs for high-frequency roll-off when using extended wiring runs. Finally, set the recommended gap voltage to -9 Vdc for standard radial vibration measurements.

Frequently Asked Questions (FAQ)

Q1: What certifications does the 330190-075-01-05 hold?
A1: This model carries CSA, ATEX, and IECEx approvals, making it suitable for installation in hazardous areas requiring explosion-proof equipment.

Q2: What is the temperature range for this extension cable?
A2: The 330190-075-01-05 operates from -52°C to +260°C (-62°F to +500°F), thanks to its PFA insulation and ETR design.

Q3: Can I use this cable with the standard 3300 series components?
A3: Yes, the 3300 XL 8 mm components are electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components when you observe the minimum bend radius.

Q4: What field wiring is recommended for the 330190-075-01-05?
A4: Bently Nevada recommends using a 3-conductor shielded triad cable, 16 to 24 AWG, with a maximum length of 305 meters (1,000 feet) between the Proximitor and the monitor.

Q5: What is the difference between the 330190-075-01-00 and 330190-075-01-05?
A5: The key difference is the agency approval option. The -05 version includes CSA, ATEX, and IECEx hazardous area certifications, while the -00 version has no such approvals.
