Bently Nevada 330190-080-01-CN — Product Specifications, Description, Applications, Advantages, and Related Models

1. Product Overview

The Bently Nevada 330190-080-01-CN is a model designation associated with the 3300 XL Extended Temperature Range (ETR) extension cable product family. Extension cables are used in non-contact proximity measurement systems to connect a proximity probe to its compatible sensor, allowing the measurement signal to be transmitted through an industrial installation.

This type of cable is used in machinery condition-monitoring systems where shaft vibration and relative shaft position are measured continuously. Typical installations include turbines, compressors, pumps, generators, and other rotating equipment that requires reliable monitoring during operation.

The extension cable is not itself a proximity probe or a vibration-monitoring instrument. It is an interconnecting component in a complete measurement chain, usually consisting of a probe, an extension cable, and a compatible proximity sensor. Correct component matching is essential because cable length, electrical characteristics, connector configuration, and temperature rating can affect system compatibility.

Model identification note: The base number 330190 identifies the ETR extension-cable family. However, the complete code 330190-080-01-CN should be checked against the applicable ordering-code table before treating every suffix as a confirmed specification. In particular, the precise meaning of CN, the connector arrangement, and the cable construction should be confirmed for this exact configuration. The tables below distinguish known family characteristics from details that require confirmation.

2. Technical Specifications

The most important dimensions for this model are the cable’s nominal length and the physical dimensions of its connector ends. Because the cable is flexible, it does not have a single rigid overall envelope like a sensor housing.

An exact weight should not be assigned without the configuration-specific data. Cable weight varies with the conductor and insulation construction, armor, connector hardware, and ferrules. If the 080 field is confirmed to mean 8.0 m, the assembly weight should be obtained for that full length and construction rather than copied from a shorter cable model.

3. Model Number Interpretation

The 330190 extension-cable family uses a structured ordering code to identify cable length, construction, and approval configuration.

The 080 length code identifies an 8.0 m cable, while 01 identifies the armored construction. The armor provides an additional mechanical barrier around the cable, which can be useful in industrial installations where the cable may encounter abrasion or incidental contact.

The CN suffix should be retained exactly when ordering a replacement. It should not be assumed to mean the same approval status as 00 or 05; the exact designation needs to match the original equipment requirements.

4. Product Introduction

The 330190-080-01-CN is an extension cable intended for use in a compatible 3300 XL proximity transducer system. The cable connects a proximity probe to its associated proximity sensor, creating the electrical link needed to transmit measurement signals.

In a typical installation, the probe is positioned near a rotating shaft without making physical contact during normal operation. The probe responds to changes in the gap between its sensing tip and the shaft. The extension cable carries the signal to the sensor, which provides the appropriate output for the monitoring system.

The 8.0 m cable length offers greater routing distance than shorter cable options. This can be helpful when the probe is installed near a bearing housing while the associated sensor is mounted in a more accessible or better-protected location.

The armored construction provides additional protection against some forms of mechanical damage. It is particularly relevant where cables are routed around machinery frames, mounting brackets, or other industrial structures. However, armor does not eliminate the need for correct cable support, appropriate bend radius, and protection against crushing or excessive tension.

The ETR design is intended for elevated-temperature service. The 3300 XL ETR cable family can support temperatures up to approximately +260°C under specified conditions. The actual allowable temperature depends on the product specification and installation conditions, and the ratings of the probe, connectors, and sensor must also be considered.

5. Detailed Technical Characteristics

5.1 Extended-temperature-range design

The ETR cable construction is designed for applications where standard cable insulation may not provide sufficient temperature capability. It is suitable for selected installations around hot machinery, provided the cable is kept within its specified operating limits.

Temperature exposure should be assessed along the entire cable route. The temperature near a turbine casing, for example, may differ substantially from the temperature at the sensor mounting point.

5.2 Armored construction

The 01 cable option indicates an armored configuration. The armor helps protect the cable against abrasion and certain incidental mechanical impacts.

The armor also affects the cable’s outside dimensions and weight. For planning purposes, the armored cable has a nominal mass of approximately 103 g/m. At 8.0 m, this corresponds to an estimated cable mass of about 0.82 kg, excluding packaging.

5.3 Electrical characteristics

The cable is part of a 75 Ω triaxial proximity measurement system. Its electrical properties must be compatible with the probe and sensor to preserve the expected system response.

For the 3300 XL ETR cable family, typical capacitance is approximately 69.9 pF/m. The minimum recommended cable bend radius is approximately 25.4 mm, and the maximum connector tightening torque is approximately 0.565 N·m. The applicable installation specification should always take precedence.

5.4 Cable length and routing

The 8.0 m length provides flexibility when the probe and sensor are separated by a relatively long cable route. The cable should be routed neatly, without unnecessary loops or tension, and should be secured so that it cannot rub against moving equipment.

The cable length is also part of the electrical configuration. A cable should not be replaced with a different length simply because the connector fits. The total transducer system must remain compatible with its specified cable length and calibration.

5.5 Connector compatibility

The connector ends must match the intended probe and sensor arrangement. Before installation, inspect the connector contacts and mating surfaces for contamination, deformation, or corrosion.

Use the prescribed tightening method. Excessive connector torque can damage the connector or affect the reliability of the connection.

6. Product Applications

Steam and gas turbines

The cable can form part of a proximity measurement system used to monitor relative shaft vibration and position. Its extended-temperature-range construction may be useful where cable routing passes through warmer areas near turbine equipment.

Industrial compressors

Compressors often require continuous monitoring of shaft behavior. The extension cable carries the probe signal to the sensor, allowing the monitoring system to process the measurement and support condition assessment.

Power generation equipment

In generator and turbine installations, the cable may connect shaft proximity probes to compatible sensors used by machinery monitoring systems. The 8.0 m length can help accommodate equipment layouts where the sensor cannot be installed close to the probe.

Pumps and motor-driven equipment

For compatible proximity measurement systems, the cable provides the electrical connection needed to monitor shaft movement. The armored construction can be useful in installations with greater exposure to mechanical contact.

Oil, gas, and process plants

Industrial process environments can contain hot equipment, vibration, and complicated cable routes. An ETR armored cable may be appropriate where both temperature capability and mechanical protection are required.

Continuous machinery condition monitoring

The cable supports continuous measurement by maintaining the signal connection between the probe and sensor. The monitoring system can then use the signal alongside other information, such as speed, temperature, and vibration, to assess equipment behavior.

7. Product Advantages

1. Extended temperature capability. The ETR cable family is designed for elevated-temperature service, with a specified upper temperature capability of approximately +260°C for applicable configurations.

2. Additional mechanical protection. The armored construction helps protect the cable from certain forms of abrasion and incidental mechanical damage.

3. Longer routing distance. The 8.0 m cable length accommodates installations where the probe and sensor are separated by a greater distance.

4. Compatible-system integration. The cable is designed for use in a proximity transducer system, supporting the signal path between the probe and sensor.

5. Support for continuous monitoring. When correctly matched and installed, the cable enables the measurement signal to reach the monitoring equipment during normal machine operation.

6. Industrial installation flexibility. The cable length and armored construction can simplify routing in demanding equipment layouts.

7. Defined replacement configuration. The ordering code distinguishes the cable family, length, and armor option, helping maintenance personnel identify the intended replacement.

8. Reduced exposure to some mechanical hazards. The protective armor can help reduce cable damage from rubbing and incidental contact, although correct routing and periodic inspection remain essential.

8. Brand and Product Series

The 3300 XL ETR extension cable is an interconnecting component rather than a stand-alone sensor. Its performance depends on the compatibility of the entire probe–cable–sensor arrangement.

When replacing an existing cable, the original full part number should be used as the primary reference. Length, armor, connector configuration, and approval designation all need to match the requirements of the installed system.

330101 is a proximity probe family, not an extension cable. The exact model determines the mounting dimensions, cable arrangement, and other mechanical details.

330180-90-CN is a proximity sensor component. It conditions the signal from compatible probe and cable assemblies; it does not replace the cable itself.

3500/42M is a monitoring module rather than a field cable or probe. It receives and processes compatible measurement signals within a monitoring system.

The model numbers in the table identify product families or representative configurations. Before ordering, confirm the full orderable part number, compatibility, exact dimensions, and net weight for the required version.

11. Installation and Maintenance Recommendations

11.1 Confirm the operating temperature

Check the temperature along the complete cable route, including areas near hot machinery and at the connector ends. The ETR cable’s temperature capability does not automatically apply to the probe, sensor, or every connector in the system.

11.2 Verify the 8.0 m length

Confirm that 8.0 m is the required length for the installed transducer system. Do not change cable length solely to make the physical routing easier without confirming electrical compatibility.

11.3 Maintain the minimum bend radius

Observe the specified minimum bend radius of approximately 25.4 mm. Avoid sharp bends, crushing, and repeated flexing that could damage the cable or affect its electrical properties.

11.4 Protect the connector ends

Keep connectors clean and undamaged. Use the prescribed tightening method and avoid exceeding the maximum specified connector torque of approximately 0.565 N·m.

11.5 Inspect cable routing

Ensure the cable is secured and kept away from moving components, sharp edges, and other sources of mechanical damage. The armor provides additional protection but does not replace proper cable support.

11.6 Check the system after replacement

After replacing the cable, confirm that the connected probe and sensor produce the expected signal. Review the monitoring channel configuration and compare readings with established baseline values.

11.7 Keep maintenance records

Record the complete part number, cable length, armor option, connector configuration, installation date, and associated probe and sensor models. This information makes future replacement and troubleshooting more efficient.
