330730-080-02-00 Bently Nevada 8m XL Cable

Bently Nevada 330730-080-02-00 3300 XL 11 mm Extension Cable

Product Introduction

The 330730-080-02-00 serves as a critical interconnection component for 3300 XL 11 mm proximity probe systems. This extension cable links the probe to the Proximitor Sensor, enabling accurate vibration, position, and speed measurements. Manufactured in the U.S.A., this model features an 8.0-meter length with a standard cable configuration. The "02" option indicates a connector protector, which safeguards the connection in humid or moist environments. Additionally, the gold-plated ClickLoc connectors lock securely into place, preventing accidental disconnection. Therefore, this cable suits demanding applications in turbines, compressors, pumps, and other rotating machinery across power generation and oil and gas industries.

Technical Specifications

This 330730-080-02-00 cable uses a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. The center conductor offers a DC resistance of 2.0 ± 0.5 ohms over the 8.0-meter length. Meanwhile, the coaxial conductor resistance measures 0.6 ± 0.2 ohms. Additionally, the typical capacitance is 69.9 pF/m (21.3 pF/ft), which maintains signal integrity over the longer cable run. The connectors are made from gold-plated brass, featuring the patented ClickLoc design that locks into place and prevents loosening from vibration.

Furthermore, the cable's linear range spans 4.0 mm (160 mils). It begins at approximately 0.5 mm (20 mils) from the target and extends from 0.5 to 4.5 mm (20 to 180 mils). This range corresponds to a voltage output of approximately -1 to -17 Vdc. The extended Deviation from Straight Line (DSL) range reaches from 0.5 to 5.0 mm (20 to 200 mils), producing -1 to -19 Vdc. However, the extended DSL range does not apply when using zener barriers. The recommended gap setting for optimal performance is 2.5 mm (100 mils).

The Incremental Scale Factor (ISF) is 3.94 V/mm (100 mV/mil) with a ±10% tolerance. This includes interchangeability error when measured in 0.5 mm (20 mil) increments over the 4.0 mm linear range. Consequently, the 330730-080-02-00 delivers consistent and reliable measurement data across its full operating range.

Mechanical and Environmental Parameters

The cable's construction emphasizes durability and protection. The standard cable weight is 45 g/m (0.5 oz/ft), totaling 0.36 kg for the 8.0-meter length. When armored with flexible AISI 302 SST and an FEP outer jacket, the weight increases to 140 g/m (1.5 oz/ft), totaling 1.12 kg. The connector protector option provides additional environmental protection by shielding the connection point from moisture and humidity. For installations requiring fluid sealing, the FluidLoc cable option is available upon request.

The tensile strength rating is 330 N (75 pounds) from probe case to probe lead, and 270 N (60 pounds) from probe lead to extension cable connectors. These high ratings prevent accidental disconnections during operation or maintenance. The operating and storage temperature range extends from -52°C to +177°C (-62°F to +351°F), accommodating extreme industrial conditions.

Additionally, the 3300 XL 11 mm probe comes standard with a locknut featuring pre-drilled safety wire holes. This enhances installation security and prevents loosening in high-vibration environments. The patented TipLoc molding method provides a robust bond between the probe tip and probe body, while the CableLoc design ensures the probe cable is securely attached with 330 N (75 lb) pull strength.

Installation Guidelines

Proper installation of the 330730-080-02-00 requires careful attention to system length requirements. The total length of the probe and extension cable must equal the specified Proximitor Sensor total length of 5 or 9 meters. This ensures accurate system calibration and optimal performance. For field wiring, we recommend using a three-conductor shielded triad cable. The maximum allowable distance between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, please consult the frequency response graph for signal rolloff details when using longer field wiring lengths.

When installing the cable, ensure the connector protector is properly seated to maintain environmental protection. The ClickLoc connectors should be securely engaged until they click into place. If using silicone tape instead of the connector protector, wrap it securely around the connection point. Nevertheless, avoid using silicone tape in turbine oil exposure applications.
