What Is Included

• 1 × Bently Nevada 330190-035-00-00 3300 XL ETR Extension Cable

• Original Factory Packaging (New & Original)

Before You Buy

• Stock Status: In Stock – Ready for immediate dispatch.

• Condition: New and Original. Each unit is 100% tested and verified before shipping.

• System Length Verification: The total electrical length of the proximity probe plus extension cable must equal the Proximitor Sensor's configured system length. The 3.5-meter cable is designed to work with probes of corresponding length to form a matched system. Length mismatch will result in measurement errors or signal attenuation.

• Installation: Installation must be performed by qualified technicians. Maintain the minimum bend radius of 25.4 mm and observe proper connector torque specifications during installation. The cable should be stored in a clean, dry environment and protected from sharp bends and mechanical damage.

• Warranty: Comes with a standard 12-month warranty covering defects in materials and workmanship.

Frequently Asked Questions

Q: What does the model number 330190-035-00-00 represent?
A: The model number breaks down as follows: 330190 = 3300 XL ETR Extension Cable series; 035 = 3.5-meter cable length; 00 = Standard cable (non-armored); 00 = No specific agency approval required.

Q: What is the function of this extension cable?
A: It transmits the probe signal to the Proximitor Sensor while preserving calibration accuracy in a 3300 XL system. It is installed between the proximity probe and the Proximitor Sensor.

Q: What is the difference between ETR and standard extension cables?
A: The ETR (Extended Temperature Range) version supports higher operating temperatures. This cable operates from -51°C to +177°C (-60°F to +350°F).

Q: Can this cable be used with existing 3300 systems?
A: Yes, the 3300 XL 8 mm system components are electrically and physically interchangeable with other 3300 series 5 mm and 8 mm transducer system components, allowing backward compatibility.

Q: What is the recommended gap setting for radial vibration monitoring?
A: The recommended gap setting is -9 Vdc, which corresponds to approximately 1.27 mm (50 mils).

Q: Can the cable be cut or shortened during installation?
