The Bently Nevada 330190-075-01-CN is a high-reliability extension cable engineered for the 3300 XL series proximity monitoring systems. Specifically, this model features the Extended Temperature Range (ETR) option, making it ideal for applications where standard cables fail due to extreme heat. Its 7.5-meter length and robust armor provide mechanical protection and stable signal transmission for radial vibration and thrust position measurements. Consequently, this cable is a critical component for maintaining asset health in power generation and heavy industry.
The 330190-075-01-CN delivers consistent electrical performance. Its triaxial design ensures minimal signal loss, while the specific resistance values are crucial for accurate sensor calibration.
Electrical Characteristics
Nominal DC Resistance (Center): The RCORE value is 1.65 ± 0.25 Ω for a 7.5-meter length, ensuring a reliable connection between the probe and the proximitor.
Nominal DC Resistance (Outer): The RJACKET is 0.49 ± 0.10 Ω, which helps maintain the integrity of the shield and reduces electromagnetic interference.
Capacitance: With a typical capacitance of 69.9 pF/m, this cable supports high-frequency response without significant signal degradation.
Field Wiring: For field wiring, we recommend using a 3-conductor shielded triad cable ranging from 0.2 to 1.5 mm² (16 to 24 AWG). The maximum distance between the Proximitor Sensor and the monitor is 305 meters (1,000 feet).
Environmental and Mechanical Data
Temperature Range: The ETR cable operates effectively from -52°C to +260°C (-62°F to +500°F). Meanwhile, the standard cable is limited to +177°C (350°F).
Material: It is insulated with perfluoroalkoxy (PFA), which provides superior resistance to chemicals and high temperatures compared to standard FEP insulation.
Cable Bend Radius: The minimum cable bend radius is 25.4 mm (1.0 in). Therefore, careful handling during installation is required to prevent internal damage.
Connector Material: The connectors are made of gold-plated brass or beryllium copper, ensuring excellent conductivity and corrosion resistance. Please apply a maximum torque of 0.565 N•m (5 in•lbf) for installation.
Weight: The armored cable weighs 103 g/m (1.5 oz/ft), providing extra strength for permanent installations.
Agency Approvals
This model includes the "CN" agency approval option, confirming it meets specific country standards. Furthermore, it complies with FCC Part 15, EMC Directive 2014/30/EU, RoHS, and maritime classification rules. It is also certified for functional safety up to SIL 3 with HFT = 1.
Sensor Pairing and Linear Range
The Bently Nevada 330190-075-01-CN is electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components. The linear range for the sensor system starts at approximately 0.25 mm from the target and extends to 2.3 mm (10 to 90 mils). The recommended gap setting for radial vibration applications is -9 Vdc, which equals approximately 1.27 mm (50 mils). Therefore, this setup allows for accurate monitoring of shaft movement.
Handling and Safety
First, ensure the cable bend radius is not less than 25.4 mm during routing to avoid performance issues. Next, connect the cable securely to both the probe and the Proximitor sensor. Remember that the maximum connector torque is 0.565 N•m to prevent stripping the threads. Finally, for optimal performance, maintain the specified field wiring length to avoid signal rolloff at high frequencies.

1. What is the difference between the standard cable and the ETR version?
The Extended Temperature Range (ETR) cable, as seen in the Bently Nevada 330190-075-01-CN, uses PFA insulation. Therefore, it can withstand temperatures up to +260°C, whereas the standard cable is limited to +177°C.
2. Can I use this cable with older 3300 sensors?
Yes, the 3300 XL components, including the 330190-075-01-CN, are electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components.
3. What is the maximum length of field wiring I can use?
You can use a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor. However, be aware of signal rolloff at high frequencies when using longer lengths.
4. How do I handle the cable to avoid damage?
Always ensure the minimum cable bend radius of 25.4 mm (1.0 in) is not exceeded. Moreover, do not exceed the connector torque specification of 0.565 N•m (5 in•lbf) during installation.
5. Is the "CN" option important for my system?
Yes, the "CN" indicates a specific country approval. Therefore, please verify that this variant of the 3300 XL cable complies with your local regulatory requirements before purchase.
