What is Bently Nevada 21747-075-00?

Bently Nevada 21747-075-00 is an unarmored 7.5 m extension cable for a compatible legacy 7200 Series 5 mm or 8 mm proximity transducer system.

Which system family uses the 21747 cable?

The 21747 cable family is used with compatible Bently Nevada 7200 Series 5 mm and 8 mm proximity systems.

What does the 075 code specify in 21747-075-00?

The 075 code specifies a 7.5 m electrical-length option, which is approximately 295.3 inches.

Does the final 00 suffix indicate cable armor?

The final 00 suffix identifies the version supplied without armor.

Where is 21747-075-00 installed in the measurement chain?

The 21747-075-00 is installed between the compatible probe lead and the matched 7200 Proximitor sensor.

Is 21747-075-00 a complete proximity transducer system?

The 21747-075-00 is only the extension cable, so a compatible probe and Proximitor sensor are also required to form the measurement system.

Can this cable be treated as a 7200 Series 11 mm component?

The 21747-075-00 must not be identified as an 11 mm cable because manufacturer legacy documentation associates the 21747 family with 7200 Series 5 mm and 8 mm systems.

What must be verified after replacing 21747-075-00?

The technician must verify the matched component family, approved total electrical length, gap voltage, monitor status and documented channel response after replacement.

Information

Overview Manuals Common Applications Product Precautions

The 21747-075-00 extends the coaxial connection between a compatible 7200 Series 5 mm or 8 mm proximity probe and its matched Proximitor sensor.

7200 Series 5 mm and 8 mm system component
7.5 m electrical-length option
Unarmored cable construction
Male-to-female coaxial extension connection

The base number 21747 identifies the legacy extension-cable family used with compatible 7200 Series 5 mm and 8 mm proximity systems. In the complete suffix, 075 identifies the 7.5 m length option and 00 identifies the version without armor. The cable must remain matched to the installed probe and Proximitor electrical-length requirement; it is not a complete transducer system and it is not an 11 mm system cable.

Important Notice: Confirm the complete 21747-075-00 marking, both connectors, probe identity and matched 7200 Proximitor requirement before replacement.

The first document organizes exact-model technical evidence; the second provides a separate evidence-led installation and commissioning workflow.

Legacy 7200 monitoring

Cable replacement in a documented 7200 Series 5 mm or 8 mm proximity measurement point.

Turbine shaft monitoring

Matched extension routing for approved radial vibration, axial position or Keyphasor measurement arrangements.

Compressor protection

Like-for-like cable service where the installed probe and Proximitor require the same electrical-length configuration.

Maintenance spares

Exact-identity spare control for legacy machinery-protection systems that still specify 21747-075-00.

Read the applicable Bently Nevada instructions before work. Verify 21747-075-00 and the installed system configuration before isolation or replacement.

Record the complete 21747-075-00 marking and both connector identities before work.

Place the monitor and affected machinery channel in the approved safe maintenance state.

Confirm that the installed probe and Proximitor belong to the 7200 Series 5 mm or 8 mm family.

Verify the required total electrical length before disconnecting the existing cable.

Inspect the unarmored cable jacket and both coaxial connectors for damage or contamination.

Route the cable without sharp bends, crushing, tension or unapproved shortening.

Reconnect the probe and Proximitor interfaces without mixing another transducer family.

Restore the channel and document gap voltage, monitor status and acceptance results.
