330190-085-00-00 Bently Nevada Standard Extension Cable

330190-085-00-00 Bently Nevada Standard Extension Cable

Product Introduction

The Bently Nevada 330190-085-00-00 is a versatile extension cable from the 3300 XL series, designed for standard industrial monitoring applications. This model features the Cable Option 00, which means it comes without an armored jacket, making it lighter and more flexible than its armored counterparts. The 330190-085-00-00 measures 8.5 meters (27.9 feet), offering ample reach for sensor placement in various machinery setups. Its extended temperature range capability allows operation in both high-heat and low-temperature environments. Furthermore, this cable is electrically and physically interchangeable with both 3300 XL and non-XL 3300 series components.

Technical Specifications of the 330190-085-00-00

The 330190-085-00-00 delivers consistent electrical performance critical for accurate proximity measurements. The nominal DC resistance from the center conductor (RCORE) is 1.87 ± 0.28 Ω, while the outer conductor resistance (RJACKET) measures 0.56 ± 0.11 Ω. Additionally, the typical capacitance is 69.9 pF/m (21.3 pF/ft), maintaining the same electrical characteristics across the entire 3300 XL cable family. These parameters ensure signal integrity over the full 8.5-meter cable length. The cable uses 75Ω triaxial construction with FEP (fluoroethylene propylene) insulation, which provides excellent dielectric properties and chemical resistance. Gold-plated brass or beryllium copper connectors offer superior corrosion resistance and reliable electrical contact.

Mechanical and Environmental Parameters

The 330190-085-00-00 operates reliably across a broad temperature spectrum, functioning from -52°C to +260°C (-62°F to +500°F). This extended range is achieved through PFA (perfluoroalkoxy) insulation, a significant upgrade over standard materials. Without the armored jacket, this cable weighs only 34 g/m (0.4 oz/ft), making it significantly lighter and more flexible than armored versions. This lighter construction simplifies installation in tight spaces and reduces the overall weight burden on connected sensors. The cable features a minimum bend radius of 25.4 mm (1.0 inch), which must be observed during routing to prevent internal conductor damage and signal degradation.

Compliance and Industry Standards

The 330190-085-00-00 meets multiple international regulatory requirements despite lacking hazardous area certifications. It complies with FCC Part 15 rules for electromagnetic emissions. For the European market, it adheres to the EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU, meeting both EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions) standards. For maritime installations, it satisfies the 2019 Rules for Conditions of Classification for both ships and offshore structures. In functional safety applications, the 3300 XL ETR cable supports SIL 2 (HFT = 0) and SIL 3 (HFT = 1) rated systems, making it suitable for safety-critical monitoring loops in general-purpose environments.

Installation Guidelines for the 330190-085-00-00

Proper installation of the 330190-085-00-00 ensures optimal performance and longevity. First, always respect the minimum bend radius of 25.4 mm (1.0 inch) during cable routing to avoid stressing the triaxial conductors. Second, apply the recommended connector torque of exactly 0.565 N•m (5 in•lbf) – over-tightening can damage the gold-plated connector interface. For field wiring connections, use a 3-conductor shielded triad cable with 16 to 24 AWG tinned conductors. The maximum total field wiring length between the Proximitor sensor and the monitor is 305 meters (1,000 feet). Additionally, consult the frequency response graphs (Figures 10 and 12) to assess high-frequency signal roll-off when using extended wiring runs. Finally, configure the recommended gap voltage to -9 Vdc for standard radial vibration measurements.
