Product Overview
The Bently Nevada 83387-100 Hardline Cable serves as a critical link for accelerometer systems operating in extreme heat. Unlike standard softline options, this 100-inch cable uses mineral insulation and a robust stainless steel overbraid to withstand temperatures up to +1200°F (+649°C). Its construction ensures signal integrity where standard cables would fail. This cable is a genuine, new product and comes in its original factory packaging.
Technical Specifications
The 83387-100 cable is engineered for performance under severe thermal stress.
Length: 100 inches (8.3 feet / 2.54 meters).
Cable Type: Hardline, mineral-insulated (MgO) with a twisted shielded pair.
Protection: Stainless steel overbraid (AISI 304) for mechanical durability.
Accelerometer Mating Connector: Mates to an MS 3100R-10SL-4P receptacle and features a Viton insert.
Interface Module Mating Connector: Mates to an MS 3106-10SL-4S disconnect connector.
Furthermore, the cable construction is designed for low noise, making it suitable for sensitive vibration measurements. Notably, the 83387-100 cable's connectors are different from those on softline cables, which use an MS 3112-8-3P connector. Therefore, always verify your interface module's compatibility before ordering.
Temperature Ratings and Environmental Limits
The primary advantage of this Hardline Cable is its exceptional temperature tolerance. This makes it the ideal choice for monitoring equipment in the hottest zones of a plant.
Cable: -65°F to +1200°F (-54°C to +649°C).
Accelerometer Connector: -65°F to +800°F (-54°C to +427°C).
Disconnect Interface Connector: -65°F to +800°F (-54°C to +427°C).
It is critical to remember that while the cable itself can handle +649°C, the system's overall temperature limit is governed by the connectors, which are rated to +427°C. Additionally, the mineral insulation is hygroscopic and will absorb moisture. For this reason, keep the cable sealed in its original bag with desiccant until you are ready to install it.
Installation Guidelines
Proper installation is vital to maintaining the performance and longevity of the Bently Nevada 83387-100. These steps will help you achieve a reliable setup.
Handling: Keep the cable in its sealed, moisture-barrier bag until the moment of installation to prevent the mineral insulation from absorbing humidity.
Connector Mating: Only hand-tighten the connectors. Over-tightening can damage the pins or the Viton insert.
Routing: Plan your cable route carefully to avoid sharp bends. The minimum bend radius for the 83387-100 is 200mm (approx. 8 inches).
Support: Use stainless steel cable ties to support the cable at regular intervals, approximately every 12 inches. This prevents stress on the connectors and the cable itself.
Service Loop: Always leave a small service loop at both ends of the cable. This prevents tension from being transmitted to the connectors, which is crucial in high-vibration environments.

Frequently Asked Questions
Q: What is the exact length of the 83387-100 cable?
A: The 83387-100 is exactly 100 inches long, which is equivalent to 8.3 feet or 2.54 meters. This model number corresponds directly to its length in inches.
Q: Can I use this Hardline Cable with a standard softline interface module?
A: No, it is not compatible. The 83387-100 cable uses an MS 3106-10SL-4S connector, while softline modules use an MS 3112-8-3P connector. You must verify that your interface module has the correct mating connector.
Q: Why is it important to keep the cable sealed before installation?
A: The cable's mineral insulation is highly hygroscopic. If exposed to ambient air for too long, it will absorb moisture, which can significantly degrade its insulation resistance and compromise measurement accuracy.
Q: What is the maximum operating temperature for the complete assembly?
A: Although the cable itself is rated to +649°C, the overall system is limited by the connectors to +427°C. Ensure that the entire installation environment does not exceed this temperature.
Q: What shipping methods are available for this cable?
A: We ship all orders via FedEx, UPS, or DHL. This ensures that your 83387-100 cable arrives quickly and safely, with full tracking available for every shipment.
