Bently Nevada 330730-080-01-00 Extension Cable
1. Product Overview
The Bently Nevada 330730-080-01-00 is a model designation associated with the 330730 extension cable family used in industrial proximity measurement systems. Extension cables provide the electrical connection between compatible proximity probes and their associated proximitor sensors, allowing sensing components and signal-conditioning electronics to be installed at appropriate locations around rotating machinery.
In industrial condition monitoring, the extension cable forms part of the complete measurement chain. A proximity probe detects changes in the gap between its sensing tip and a conductive target, such as a rotating shaft. The associated sensor electronics process the resulting signal so that compatible monitoring equipment can use it to assess shaft movement and vibration-related behavior.
The cable is not an independent vibration sensor. Its role is to provide the required electrical connection while meeting the mechanical and electrical requirements of the complete measurement system.
Model-specific note: The exact configuration of the 330730-080-01-00 has not been confirmed here. Its cable length, connector arrangement, dimensions, weight, and the precise meaning of each ordering-code segment should be verified against the product label before purchasing or installing it. The information below distinguishes general product-family characteristics from values that remain unverified.

3. Detailed Product Description
3.1 Product Construction and Cable Configuration
The 330730-080-01-00 ordering configuration identifies an 8.0 m (26.2 ft) armored extension cable for the 3300 XL 11 mm proximity measurement system. The -01 option identifies the armored cable configuration, while -00 indicates that agency approval is not required for this version. This is a different ordering code from the model ending in -CN, so the two should not be assumed to have identical approval requirements.
The armored construction is intended to provide additional mechanical protection compared with an unarmored cable. The cable construction is described as 75-ohm triaxial cable with FEP insulation and flexible stainless-steel armor with an FEP outer jacket. The exact assembly and its markings should still be checked before installation.
3.2 Electrical Characteristics
The extension cable forms part of the proximity transducer system’s electrical circuit. Its characteristics are selected to work with the compatible probe and proximitor rather than as a general-purpose cable.
| Parameter | Specification |
|---|---|
| Cable type | 3300 XL 11 mm extension cable |
| Cable length | 8.0 m (26.2 ft) |
| Cable electrical construction | 75 Ω triaxial |
| Insulation material | FEP |
| Typical capacitance | 69.9 pF/m |
| Typical capacitance per foot | 21.3 pF/ft |
| Center-conductor resistance for 8 m | 2.0 ± 0.5 Ω |
| Jacket resistance for 8 m | 0.6 ± 0.2 Ω |
| Cable armor | Flexible AISI 302 stainless steel |
| Outer jacket | FEP |
| Connector style | ClickLoc-type connectors; verify the supplied assembly |
| Agency approval option | -00: approval not required |
| Typical operating temperature | Approximately -52°C to +177°C; confirm the applicable specification |
| Minimum cable bend radius | Approximately 25.4 mm, subject to the applicable specification |
The cable should be used only with a compatible probe and proximitor arrangement. The complete measurement system must satisfy the specified electrical configuration, including its total cable length and connector arrangement.
3.3 Dimensions and Weight
The cable’s overall length is 8.0 m. Its physical dimensions and weight can be recorded as follows, with the distinction between verified ordering information and unconfirmed packaging measurements kept clear.
| Physical parameter | Specification |
|---|---|
| Cable length | 8.0 m (26.2 ft) |
| Cable diameter | Approximately 11 mm is reported for this product family; confirm the exact armored assembly |
| Minimum bend radius | Approximately 25.4 mm |
| Connector dimensions | Not independently confirmed |
| Overall packed dimensions | Depend on packaging |
| Estimated cable assembly weight (kg) | Approximately 1.12 kg based on 140 g/m for armored cable; confirm the actual supplied unit |
| Reported shipping weight (kg) | Approximately 2 kg in one listing; packaging-dependent |
Weight note: Published commercial listings do not agree on the weight of this model. The 1.12 kg figure is a calculation based on the stated armored-cable mass per metre, not a certified net weight for every supplied assembly. The shipping weight includes packaging and may differ substantially. Confirm the actual weight before using it for freight or inventory records.
4. Product Applications
4.1 Turbine Shaft Monitoring
The cable can be used as part of a compatible proximity measurement installation for turbine shaft monitoring. It connects the probe and sensor electronics so that the system can measure changes in the gap between the probe and the shaft.
These measurements may help maintenance teams assess shaft vibration and relative displacement during machine operation.
4.2 Compressor Monitoring
Industrial compressors often operate under continuous load and may be installed in areas where cable routing is restricted. The armored cable construction can help protect the cable against mechanical abrasion when installed appropriately.
Correct cable routing remains essential. The armor does not eliminate the need to observe bend-radius requirements, protect the connectors, or keep the cable away from moving machinery.
4.3 Pump and Rotating Equipment Monitoring
In suitable pump installations, proximity sensors can be used to monitor shaft movement. The extension cable provides the connection between the probe and its associated sensor electronics.
For pumps exposed to oil, moisture, or process fluids, the actual cable and connector protection requirements should be assessed carefully. The -01 configuration should not be assumed to include additional connector sealing or a connector protector.
4.4 Industrial Machinery Condition Monitoring
The cable may form part of a larger machinery monitoring arrangement for rotating equipment, including turbines, compressors, and other compatible machines.
Its role is to maintain the electrical connection required by the sensing system. The cable does not independently identify mechanical faults; it supports the collection of measurements used by monitoring equipment and maintenance personnel.
5. Product Advantages
5.1 Additional Mechanical Protection
The flexible metal armor helps protect the cable against abrasion and some forms of mechanical contact that may occur in industrial installations.
This is useful where cables must be routed through equipment spaces or near structural surfaces, provided the installation follows the applicable mechanical requirements.
5.2 Supports an 8-Metre Installation
The 8.0 m cable length provides installation flexibility where the probe and proximitor need to be positioned apart.
The chosen length must still match the requirements of the complete proximity measurement system. A longer cable is not automatically suitable simply because it reaches the required location.
5.3 Supports Signal Transmission
The specified cable construction and electrical characteristics are intended for use within the compatible proximity measurement system.
Using the correct cable helps maintain the electrical arrangement for which the system is designed.
5.4 Suitable for Demanding Industrial Environments
The armored construction is useful in installations where mechanical protection is an important consideration. The actual suitability for a particular environment depends on temperature, moisture, oil exposure, chemical conditions, routing, and the connector arrangement.
5.5 Simplifies Like-for-Like Replacement
When the installed system already uses the same configuration, a verified replacement can simplify maintenance. The complete model number must be checked to avoid confusing armored and unarmored options or versions with different connector-protection and approval requirements.
