Bently Nevada 330730-040-13-05 Extension Cable

Bently Nevada 330730-040-13-05 Extension Cable

Product Introduction

The Bently Nevada 330730-040-13-05 is a high-performance extension cable explicitly designed for the 3300 XL 11 mm proximity transducer system. This 4.0-meter (13.1 feet) cable features an armored construction with a flexible AISI 302 stainless steel outer jacket and an FEP outer layer. It includes the FluidLoc option, which effectively prevents oil and process liquids from escaping through the cable interior. Additionally, the connector protector offers robust defense against humidity and moisture, making it suitable for challenging field conditions. This model carries Multiple Approvals (Option 05), confirming its compliance with various international standards for industrial safety and performance. This 3300 XL extension cable ensures a secure, gold-plated ClickLoc connection that locks firmly into place, preventing accidental disconnection due to vibration.

Technical Specifications

Electrical Parameters
This cable provides stable and precise signal transmission. Its typical capacitance is 69.9 pF/m (21.3 pF/ft) . The DC resistance from the center conductor to center conductor (RCORE) is 1.0 ± 0.25 ohms, while the resistance from the coaxial conductor to coaxial conductor (RJACKET) is 0.3 ± 0.1 ohms. Such precise electrical characteristics guarantee that the signal integrity from the 3300 XL probe remains uncompromised over its length.

Material and Construction
The cable uses a 75 Ω triaxial, fluoroethylene propylene (FEP) insulated design. The optional armor consists of flexible AISI 302 SST with an additional FEP outer jacket, providing excellent mechanical protection. This material choice ensures durability against abrasion and chemical exposure. Furthermore, the unique CableLoc design secures the cable to the probe tip, providing an impressive 330 N (75 lb) pull strength, preventing damage during installation or maintenance.

Environmental Ratings
The Bently Nevada 330730-040-13-05 operates reliably under extreme conditions. Its operating and storage temperature range is from -51°C to +177°C (-60°F to +351°F) . This broad tolerance makes it an excellent choice for applications near turbines, compressors, and other high-heat rotating machinery. The connector protector adds a layer of safety in humid or moist environments, ensuring a long service life.

Mechanical and Physical Properties

The cable weighs approximately 140 g/m (1.5 oz/ft) with armor, compared to 45 g/m (0.5 oz/ft) without it. It is compatible with field wiring ranging from 0.2 to 1.5 mm² (16 to 24 AWG) . For optimal performance, Bently Nevada recommends using a three-conductor shielded triad cable. The maximum length of field wiring between the 3300 XL Proximitor Sensor and the monitor should not exceed 305 meters (1,000 feet) to avoid signal rolloff at high frequencies. The connector system uses gold-plated brass ClickLoc connectors, which are standard across all 3300 XL transducer components. These connectors lock into place securely, eliminating the risk of loosening from machine vibration.

Installation Guidelines

Proper installation is crucial for accurate readings. First, ensure the extension cable connection is clean and dry before attaching it to the probe and Proximitor Sensor. Apply the included silicone tape for additional protection, but note that it is not recommended if the connection is exposed to turbine oil. Instead, rely on the integral connector protector. The recommended gap setting for the 3300 XL 11 mm probe is 2.5 mm (100 mils) . The linear range begins at approximately 0.5 mm (20 mils) from the target and extends to 4.5 mm (180 mils). When routing the armored extension cable, avoid sharp bends that could damage the FEP outer jacket. Finally, secure the cable using appropriate clamps to prevent strain on the connectors.

Frequently Asked Questions (FAQ)

1. What is the primary purpose of the FluidLoc option?
The FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable's interior, ensuring a cleaner and safer operating environment.

2. Can I use this extension cable without the connector protector?
Yes, you can use the provided silicone tape instead. However, avoid using silicone tape in applications where the connection will be exposed to turbine oil, as it can degrade.

3. Which probe threads are compatible with this extension cable?
This cable is designed for the 3300 XL 11 mm probe system, which is available in various thread types, including armored and unarmored ½-20, 5⁄8 -18, M14 X 1.5, and M16 X 1.5 configurations.

4. What is the maximum distance for field wiring?
The field wiring between the 3300 XL Proximitor Sensor and the monitor should not exceed 305 meters (1,000 feet) to prevent high-frequency signal attenuation.

5. How do the ClickLoc connectors ensure reliability?
ClickLoc connectors lock firmly into place, preventing the connection from loosening due to vibration. This design ensures a consistent and reliable electrical connection over time.
