Product Overview

The Bently Nevada 84661-20 serves as a high-integrity Extension Cable for the 3300 XL Proximity Transducer System. This 2.0-meter cable links the proximity probe to the Proximitor sensor, facilitating the transmission of raw eddy current signals without loss or interference. It maintains the precise electrical length required for accurate scale factor calibration in vibration and position monitoring loops. We supply this cable as 100% Brand New and Original in Factory Packing, ensuring the electrical impedance matches the strict requirements of your Bently Nevada 3300 or 3500 series monitoring rack.

Engineering Advantages

Precision Impedance Matching: The 84661-20 features a specific electrical capacitance that completes the oscillator circuit within the Proximitor. This ensures the output remains at the standard –200 mV/mil scale factor, providing accurate shaft displacement data.
Superior Thermal Resilience: FEP insulation allows the cable to operate in temperatures reaching +170°C. This makes it suitable for routing through hot turbine housings and compressor frames where standard industrial cables would melt or degrade.
Corrosion-Resistant Connectors: Gold-plated miniature connectors prevent oxidation in humid and chemically aggressive environments. This maintains a low-resistance connection, which is vital for the low-voltage signals used in eddy current technology.
Oil and Chemical Protection: The outer jacket resists degradation from synthetic lubricants, hydraulic fluids, and common industrial solvents. This prevents cable swelling or hardening that could lead to signal failure or physical breakage during machinery vibration.
Flexible Routing Design: The small diameter and specified bend radius allow for installation in narrow conduit runs and tight machine internal spaces. This facilitates clean cable management from the probe mounting point to the external junction box.

FAQs

Can I use the 84661-20 with any proximity probe?

This cable works specifically with the 3300 XL series and compatible proximity probes. To maintain calibration accuracy, you must ensure the total system length (probe length + extension cable length) matches the configuration of your Proximitor sensor (typically 5m or 9m).
Do I need special tools to connect this cable?

No. The miniature coaxial connectors feature a "click" lock mechanism. However, we recommend using a connector protector or heat-shrink tubing to prevent the connectors from loosening due to machine vibration or fluid ingress.
Does this cable support both vibration and position measurements?

Yes. The 84661-20 transmits the full frequency spectrum from DC to 10 kHz. This allows the Proximitor to process both static axial position and dynamic radial vibration signals simultaneously.
How do I verify the authenticity of the cable?

Every 84661-20 we ship is 100% Brand New and Original. The cable includes factory-applied labels with the Bently Nevada part number and date code, ensuring full traceability and compliance with your facility’s quality standards.
