Product Overview

The Bently Nevada 21747-080-00 acts as the high-precision electrical bridge between a proximity probe and a Proximitor Sensor. This extension cable maintains signal integrity for eddy current measurement systems, enabling accurate vibration and shaft position monitoring of critical rotating machinery. We supply this cable in 100% Brand New and Original factory condition, ensuring the impedance and capacitance match perfectly with your existing Bently Nevada monitoring hardware for calibrated accuracy.

Technical Specifications

The 21747-080-00 utilizes specialized coaxial construction to prevent signal attenuation over long distances.

Engineering Advantages

• Optimized Signal Transmission: This cable features tight capacitance tolerances to ensure the Proximitor Sensor receives a clean, unshielded eddy current signal. This precision prevents measurement drift and maintains the linearity of vibration data.

• Flexible Routing: The "Without Armor" (00) option provides maximum flexibility. This allows engineers to route the cable through tight conduit runs or internal machine galleries where rigid armored cables cannot pass.

• Rugged Connector Integrity: The factory-installed connectors resist the oils and industrial fluids commonly found in turbine and compressor housings. These connectors provide a secure, low-resistance mechanical lock that prevents signal interruption due to machine vibration.

• Calibrated System Matching: Using the correct 8-meter length ensures the total system electrical length matches the Proximitor's calibration. This eliminates the need for field recalibration when replacing damaged leads.

FAQs

• Can I use this 8-meter cable to replace a 5-meter cable?

  No. Proximitor systems are calibrated for a specific total electrical length (typically 5m or 9m total including the probe lead). Changing the extension cable length will alter the system's sensitivity and accuracy. Always match the replacement cable to your system's original specifications.

• How do I protect this cable if it is not armored?

  We recommend installing the 21747-080-00 inside a dedicated liquid-tight flexible conduit or rigid electrical conduit. This provides physical protection against impact and sharp edges while retaining the ease of routing offered by a non-armored cable.

• Is this cable compatible with 3300 XL series probes?

  The 21747 series is primarily associated with the 7200 and older 3300 systems. While some connectors may look similar, the 3300 XL system typically uses a different cable part number (such as 330130). Always verify your Proximitor's required cable type before installation.

• In what condition is this cable supplied?

  We guarantee the Bently Nevada 21747-080-00 is 100% Brand New and original. It ships in original manufacturer packaging and includes a full factory warranty.
