The Bently Nevada 330190-075-01-00 is a high-performance extension cable that forms a critical part of the 3300 XL monitoring system. This model is specifically designed for the Extended Temperature Range (ETR), ensuring reliable signal transmission where standard cables would fail. Its primary function is to connect the 3300 XL Proximitor Sensor to the target monitoring device. The 330190-075-01-00 features an armored jacket, providing exceptional protection against physical damage and mechanical stress in demanding industrial applications. Consequently, this cable significantly enhances the overall durability and longevity of your vibration monitoring setup.
The cable offers precise electrical characteristics critical for accurate data acquisition. The nominal DC resistance from the center conductor is 1.65 ± 0.25 Ω, while the outer conductor resistance is 0.49 ± 0.10 Ω. Additionally, its typical capacitance is 69.9 pF/m (21.3 pF/ft). These parameters ensure that the signal integrity from the sensor is maintained over the cable's 7.5-meter length. The connector is made from gold-plated brass or beryllium copper, ensuring excellent conductivity and corrosion resistance. It is vital to observe the maximum connector torque of 0.565 N•m (5 in•lbf) during installation to prevent damage.
A key feature of the 330190-075-01-00 is its extended temperature range. Unlike standard cables, this variant operates and stores effectively between -52°C and +260°C (-62°F to +500°F). This is made possible by its PFA (perfluoroalkoxy) insulation, a significant upgrade over standard FEP insulation. Furthermore, the cable has a minimum bend radius of 25.4 mm (1.0 inch), which must be respected during routing to avoid internal damage. The armored version weighs approximately 103 g/m (1.5 oz/ft), compared to 34 g/m for the unarmored version, reflecting its robust construction.
The 330190-075-01-00 is manufactured to meet stringent industry standards. It complies with FCC regulations and adheres to the European Community EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU. For functional safety applications, it is rated for SIL 2 (HFT = 0) and SIL 3 (HFT = 1). Moreover, it meets the Maritime 2019 Rules for Classification, making it suitable for both offshore and onshore industrial applications. This broad compliance allows the 3300 XL cable to be deployed globally with confidence.
Proper installation of the 330190-075-01-00 is essential for optimal performance. First, always respect the minimum bend radius of 25.4 mm (1.0 inch) to avoid damaging the internal triaxial conductors. Next, apply the correct torque of 0.565 N•m when tightening the connector. For field wiring, use a 3-conductor shielded triad cable with a gauge between 16 and 24 AWG. Keep the total field wiring length within 305 meters (1,000 feet) to maintain signal quality. Additionally, refer to the frequency response graphs for high-frequency roll-off considerations when using longer wiring runs. Finally, set the recommended gap voltage to -9 Vdc for standard radial vibration measurements.
