Bently Nevada 330190-075-00-05 | 3300 XL ETR Extension Cable

Bently Nevada 330190-075-00-05 3300 XL ETR Extension Cable – Product Introduction

The Bently Nevada 330190-075-00-05 belongs to the trusted 3300 XL series. It serves as a critical link between the Proximitor Sensor and the monitoring system. This extension cable features an extended temperature range design. Its PFA insulation allows operation in harsh thermal environments. The cable length reaches 7.5 meters, offering flexible installation options. Additionally, it holds multiple agency approvals for global industrial use. This 3300 XL ETR extension cable ensures reliable signal transmission in vibration monitoring setups.

Electrical Characteristics

The Bently Nevada 330190-075-00-05 exhibits precise electrical properties. Its nominal DC resistance from center conductor to center conductor measures 1.65 ± 0.25 Ω for the 7.5-meter length. Furthermore, the outer conductor resistance (RJACKET) is 0.49 ± 0.10 Ω. The extension cable capacitance typically runs at 69.9 pF/m (21.3 pF/ft). These values ensure accurate signal integrity. For field wiring, we recommend using 0.2 to 1.5 mm² (16 to 24 AWG) tinned wire. Specifically, a 3-conductor shielded triad cable works best. The maximum allowable field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, longer lengths may affect high-frequency response.

Linear Range and Gap Setting

This 3300 XL ETR extension cable supports a 2 mm (80 mils) linear range. The linear range begins at approximately 0.25 mm (10 mils) from the target. It extends from 0.25 to 2.3 mm (10 to 90 mils), correlating to roughly –1 to –17 Vdc. For radial vibration applications, the recommended gap setting is -9 Vdc. This corresponds to approximately 1.27 mm (50 mils). Therefore, proper gap adjustment ensures optimal sensor performance.

Temperature Range and Cable Material

The extended temperature range cable uses perfluoroalkoxy (PFA) insulation. This material supports an operating and storage temperature range from -52°C to +260°C (-62°F to +500°F). In contrast, the standard cable option uses fluoroethylene propylene (FEP) insulation, rated for -52°C to +177°C. Consequently, the Bently Nevada 330190-075-00-05 suits extreme environments. Its minimum cable bend radius is 25.4 mm (1.0 in). Moreover, the connector features gold-plated brass or beryllium copper material. The maximum connector torque is 0.565 N•m (5 in•lbf).

Mechanical and Environmental Parameters

The standard extension cable weighs approximately 34 g/m (0.4 oz/ft). For armored versions, the weight increases to 103 g/m (1.5 oz/ft). The connector material uses gold-plated brass or gold-plated beryllium copper, ensuring corrosion resistance and reliable contact. Additionally, the cable design meets rigorous industrial standards. Its small bend radius facilitates installation in tight spaces. Meanwhile, the PFA insulation provides excellent chemical resistance and dielectric strength. These mechanical properties make the 3300 XL ETR extension cable durable and long-lasting.

Compliance and Certifications

The Bently Nevada 330190-075-00-05 complies with FCC Part 15 regulations. Operation is subject to two conditions: this device may not cause harmful interference, and it must accept any interference received. For EMC, it meets European Community Directive 2014/30/EU, following EN 61000-6-2 (Immunity for Industrial Environments) and EN 61000-6-4 (Emissions for Industrial Environments). It also adheres to RoHS Directive 2011/65/EU. For maritime applications, it satisfies the 2019 Rules for Conditions of Classification, Part 1, sections 1-1-1/7.7, 1-1-A3, and 1-1-A4, as well as offshore unit standards 1-1-4/9.7, 1-1-A2, and 1-1-A3. In functional safety contexts, this cable supports SIL 2 with HFT = 0 and SIL 3 with HFT = 1.

Installation Guidelines for the 3300 XL ETR Extension Cable

Proper installation of the Bently Nevada 330190-075-00-05 ensures accurate vibration measurements. First, verify the cable length and confirm it matches your system requirements. Next, inspect the connector for any damage before mating. Use the recommended torque of 0.565 N•m (5 in•lbf) when tightening. Avoid exceeding the minimum bend radius of 25.4 mm (1.0 in) during routing. Also, secure the cable away from high-vibration sources or sharp edges. For field wiring connections, select 0.2 to 1.5 mm² (16 to 24 AWG) tinned copper conductors. A 3-conductor shielded triad cable is strongly recommended. Keep the total field wiring length within 305 meters (1,000 feet) to maintain signal fidelity. Finally, set the probe gap to -9 Vdc for radial vibration monitoring. This setting typically yields a 1.27 mm (50 mils) gap, placing the sensor in its optimal linear range.

Frequently Asked Questions

Q1: What is the maximum temperature rating for the Bently Nevada 330190-075-00-05?
This cable handles temperatures from -52°C to +260°C (-62°F to +500°F) due to its PFA insulation. It is ideal for high-heat industrial environments.

Q2: Can I use this cable with standard 3300 non-XL components?
Yes, the 3300 XL 8 mm components are electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components, provided you observe the minimum cable bend radius of 25.4 mm.

Q3: What field wiring gauge works best with this extension cable?
We recommend using 0.2 to 1.5 mm² (16 to 24 AWG) tinned copper wire. A 3-conductor shielded triad cable yields the best noise immunity and signal quality.

Q4: How long can the field wiring be between the Proximitor Sensor and the monitor?
The maximum allowable field wiring length is 305 meters (1,000 feet). Longer runs may cause signal roll-off at high frequencies, so always check the frequency response graphs for your specific setup.
