Product Overview

The Bently Nevada 45358-09 is a 9-meter Softline extension cable for accelerometer interface modules. This cable connects an accelerometer to an interface module in monitoring systems. The accelerometer mating connector mates to an MS 3100R-10SL-4P receptacle and includes a Viton insert. The interface module mating connector mates to an MS 3112-8-3P for secure attachment. A twisted shielded pair with low noise construction forms the core of this cable. Convoluted Teflon tubing protects the entire cable assembly. Additionally, the rear of both connectors features potting for environmental sealing. The 45358-09 suits applications requiring reliable signal transmission in demanding conditions.

Softline Cable Construction

The 45358-09 uses a twisted shielded pair with low noise construction for signal integrity. This design minimizes electromagnetic interference pickup along the cable length. Convoluted Teflon tubing protects the entire assembly from abrasion and chemicals. Teflon also provides excellent thermal stability across the operating range. For additional environmental protection, the rear of both connectors is potted. Consequently, the Bently Nevada 45358-09 delivers clean accelerometer signals even in electrically noisy environments.

Connector Compatibility

The accelerometer mating connector mates specifically to an MS 3100R-10SL-4P receptacle. A Viton insert provides superior chemical and temperature resistance compared to standard materials. The interface module mating connector mates to an MS 3112-8-3P for secure attachment. Both connectors follow military standard (MS) specifications for reliable performance. For this reason, the 45358-09 works with standard Bently Nevada accelerometer interfaces.

Temperature Ratings

Temperature ratings vary significantly across the three components of the 45358-09. The cable itself operates from -54°C to +204°C (-65°F to +400°F). The accelerometer mating connector operates from -54°C to +200°C (-65°F to +392°F). However, the interface module mating connector has a narrower range of -45°C to +93°C (-50°F to +200°F). Therefore, the overall system temperature rating is limited by the interface module connector. For high-temperature applications, consider the Hardline version of this cable.

Hardline Cable Alternative

Although the 45358-09 is a Softline cable, Bently Nevada also offers Hardline cables for extreme temperatures. Hardline cables use mineral insulation instead of Teflon. A stainless steel overbraid provides mechanical protection for Hardline versions. The accelerometer mating connector remains the same (MS 3100R-10SL-4P with Viton insert). However, the disconnect interface mating connector changes to MS 3106-10SL-4S. Hardline cable temperature ranges extend from -54°C to +649°C (-65°F to +1200°F). The accelerometer mating connector reaches -54°C to +427°C (-65°F to +800°F) in Hardline versions. Similarly, the disconnect interface mating connector spans -54°C to +427°C (-65°F to +800°F). For applications requiring the 45358-09, the Softline version suits most industrial needs.

Low Noise Construction

The twisted shielded pair design in the 45358-09 actively rejects common mode noise. Shielded construction prevents external electrical interference from corrupting accelerometer signals. Low noise construction specifically addresses triboelectric noise caused by cable movement. For vibration monitoring applications, this low noise characteristic proves essential. Consequently, the Bently Nevada 45358-09 maintains signal integrity even with cable flexing.

Environmental Protection

Convoluted Teflon tubing provides excellent chemical resistance for the 45358-09. Teflon resists most industrial chemicals, oils, and solvents. The tubing also offers mechanical protection against abrasion and crushing. Potting at the connector rear prevents moisture ingress at the cable-to-connector junction. Viton inserts in the accelerometer connector resist high temperatures and chemical attack. For harsh industrial environments, these protective features ensure long cable life.

Installation Guidelines

Follow these steps for proper installation of the 45358-09.

1. Inspect both connectors for damage or debris before installation.

2. Connect the accelerometer end to the MS 3100R-10SL-4P receptacle. Ensure the Viton insert seals properly.

3. Connect the interface module end to the MS 3112-8-3P receptacle.

4. Route the cable away from high voltage sources to avoid electrical noise pickup.

5. Secure the cable with tie wraps every 30 centimeters to prevent movement.

6. Avoid sharp bends that could damage the convoluted Teflon tubing.

7. Verify the potting at connector rears remains intact before installation.

8. Test continuity after installation to confirm proper connection.

Note: The 45358-09 temperature rating is limited by the interface module connector to -45°C to +93°C. For higher temperature applications, use the Hardline cable version. Do not exceed the minimum bend radius of the Teflon tubing.

Common FAQs

1. What is the length of the 45358-09?

This cable measures 9 meters in total length. The 09 suffix in the part number indicates this specific length. Other lengths are available with different part number suffixes. For example, shorter or longer Softline cables can be ordered for specific applications. The Bently Nevada 45358-09 suits installations requiring 9-meter runs between accelerometer and interface module.

2. What connectors does the 45358-09 use?

The accelerometer end uses an MS 3100R-10SL-4P receptacle with a Viton insert. The interface module end uses an MS 3112-8-3P connector. Both connectors follow military standard specifications for reliability. Viton inserts provide superior chemical and temperature resistance. Consequently, the 45358-09 mates securely with standard Bently Nevada accelerometer systems.

3. What is the temperature range of the 45358-09?

The cable operates from -54°C to +204°C (-65°F to +400°F). The accelerometer connector operates from -54°C to +200°C (-65°F to +392°F). However, the interface module connector limits overall system temperature to -45°C to +93°C (-50°F to +200°F). Therefore, the 45358-09 suits moderate industrial environments but not extreme high-temperature locations.

4. What is the difference between Softline and Hardline cables?

Softline cables like the 45358-09 use Teflon insulation and convoluted Teflon tubing. Hardline cables use mineral insulation with stainless steel overbraid instead. Softline operates to +204°C maximum, while Hardline operates to +649°C. Hardline also uses a different disconnect interface connector (MS 3106-10SL-4S). For most industrial applications below +200°C, the 45358-09 Softline cable works perfectly.

5. How does the 45358-09 reduce electrical noise?

A twisted shielded pair with low noise construction forms the core of this cable. The twisted pair cancels magnetic interference through conductor geometry. The shield blocks electric field interference from external sources. Low noise construction specifically reduces triboelectric noise from cable movement. For sensitive accelerometer signals, the Bently Nevada 45358-09 maintains signal clarity.
