330190-080-00-CN Bently Nevada 8.0m Cable

Bently Nevada 330190-080-00-CN 3300 XL ETR Extension Cable

Product Introduction

The Bently Nevada 330190-080-00-CN is a high-quality extension cable built for the 3300 XL series. It provides a secure and reliable link between proximity probes and monitoring instruments. This model excels in extended temperature range (ETR) applications where standard cables may fail. Additionally, it ensures consistent performance and accurate data under severe thermal stress.

Technical Specifications

The Bently Nevada 330190-080-00-CN measures exactly 8.0 meters (26.2 feet) in length. Its center conductor to center conductor DC resistance is 1.76 ± 0.26 Ω. Meanwhile, the outer conductor to outer conductor resistance is 0.53 ± 0.11 Ω. The typical capacitance of this extension cable is 69.9 pF/m (21.3 pF/ft). This cable uses 75Ω triaxial construction with perfluoroalkoxy (PFA) insulation. Furthermore, its connectors are crafted from gold-plated brass or beryllium copper for excellent conductivity and corrosion resistance.

Mechanical and Environmental Parameters

The 330190-080-00-CN supports an impressive operating and storage temperature range from -52°C to +260°C (-62°F to +500°F). Its minimum bend radius is 25.4 mm (1.0 inch), which helps prevent internal damage during installation. The standard cable weighs 34 g/m (0.4 oz/ft), while the armored version weighs 103 g/m (1.5 oz/ft) for added mechanical protection. Moreover, the maximum connector torque is rated at 0.565 N•m (5 in•lbf). These specifications make it suitable for demanding industrial environments like turbines and compressors.

Compliance and Certifications

This extension cable meets a wide array of global standards. First, it complies with FCC Part 15 for electromagnetic interference. Next, it conforms to the European EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU. For maritime applications, it satisfies the 2019 Rules for Conditions of Classification for both vessels and offshore units. In terms of functional safety, this cable supports SIL 2 with HFT = 0 and SIL 3 with HFT = 1. These approvals guarantee its reliability in safety-critical systems.

Installation and Field Wiring Guidelines

For field wiring, we strongly recommend using a 3-conductor shielded triad cable. The acceptable wire gauge ranges from 0.2 to 1.5 mm² (16 to 24 AWG). Besides that, the total field wiring length between the Proximitor Sensor and the monitor must not exceed 305 meters (1,000 feet). However, you should review the frequency response graphs for high-frequency signal rolloff with extended wiring runs. The linear range for this system starts at roughly 0.25 mm (10 mils) from the target. Moreover, it extends from 0.25 to 2.3 mm (10 to 90 mils), which corresponds to -1 to -17 Vdc. For radial vibration measurements, we recommend a gap setting of -9 Vdc, equivalent to approximately 1.27 mm (50 mils). Finally, this component is fully interchangeable with non-XL 3300 5 mm and 8 mm components when you respect the minimum bend radius.

Frequently Asked Questions (FAQ)

1. What is the key advantage of choosing the 8.0-meter version over the 7.5-meter one?
The 8.0-meter option provides extra reach for installations where the monitor is farther from the probe. It maintains the same high-temperature rating and electrical performance.

2. Can I use this cable in a hazardous area with high ambient temperatures?
Yes, the PFA insulation allows continuous operation up to 260°C. This makes it well-suited for gas turbines, steam turbines, and other hot-section machinery.

3. Is this cable compatible with existing 3300 non-XL systems?
Absolutely. The 330190-080-00-CN is electrically and physically interchangeable with older 3300 5 mm and 8 mm components, provided you observe the minimum bend radius.

4. What happens if I exceed the recommended field wiring length of 305 meters?
Exceeding 305 meters may cause significant signal attenuation and rolloff at higher frequencies. Therefore, you should consult the frequency response graphs to evaluate performance impact.

5. Which carriers do you use for shipping this extension cable?
We use FedEx, UPS, and DHL as our trusted shipping partners to ensure your order arrives on time and in perfect condition.
