MORE INFORMATION

Overview Manuals Technical notes Product Applications Electrical Length Match

Features:

  • 6.5 Meter (21.3 ft) Standard Coaxial Extension Cable
  • Wide 0 Hz to 10 kHz Frequency Response for Complete Vibration Spectrum
  • Complete Interchangeability with Matched-Length Components
  • Stainless Steel Armor Option for Enhanced Mechanical Protection
The Bently Nevada 21747-065-01 is a coaxial extension cable from the company's legacy 7200 Series 5 mm / 8 mm Proximity Transducer System, designed to serve as the critical signal transmission link between the eddy current probe's integral cable and the Proximitor sensor in non-contact vibration and position monitoring applications. The 21747-065-01 part number decodes as follows: 21747 designates the 7200 Series extension cable family; 065 indicates a 6.5-meter (21.3 ft) total cable length; and 01 confirms the stainless steel armor option for enhanced mechanical protection. This cable is specifically designed to be combined with a probe having an integral lead of appropriate length to achieve a standard system length of either 5 meters or 9 meters from the probe tip to the Proximitor sensor.

The 21747-065-01 Bently Nevada Coaxial extension cable may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 21747-065-01 Coaxial extension cable Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The extension cable is constructed as a 95 Ω characteristic impedance coaxial cable, precisely matched to the impedance of the probe's integral lead and the Proximitor's input circuitry. This impedance matching is essential for maintaining signal integrity across the entire transducer system, preventing reflections and standing waves that could distort the high-frequency eddy current signal. The cable's frequency response spans 0 Hz (DC) to 10 kHz (–3 dB), faithfully transmitting both the DC offset component (representing static gap distance) and the AC modulation component (representing dynamic vibration) from the probe to the Proximitor. This wide bandwidth ensures that low-frequency rotor unbalance (typically 1× running speed, e.g., 60 Hz for a 3,600 RPM machine) and high-frequency bearing defect frequencies (up to several kHz) are both captured with equal fidelity.

Verify System Length: The total electrical length of the system must strictly combine to either 5.0 meters or 9.0 meters.
Cable Rule: Because the 21747-065-01 has a dedicated physical length of 6.5 meters, it must be matched exclusively with a 7200 Series probe that provides a 2.5-meter length to achieve a calibrated 9.0-meter system length.
Do Not Alter: Never cut, splice, or shorten the coaxial cable. Modifying the cable length alters its electrical impedance and shifts the sensor's calibration curve.
