More Information

Overview Manuals Cable Build 5 m Signal Path Operating Limits Product Applications

Features:

  • Four-metre extension: The 040 option contributes 4.00 m to a 7200 proximity-transducer loop.
  • Unarmored cable: The 00 option omits stainless-steel lead armor.
  • Five-metre arrangement: A 1.00 m integral probe lead and this extension are specified with the 18745-03 Proximitor.
The extension cable carries the probe signal along the planned 7200 transducer path rather than generating a measurement independently.

The 7200 ordering table distinguishes the unarmored 00 construction from the separately offered armored 01 option.

Cable and probe share an operating-temperature range of -34 to +177 °C, while the Proximitor has a separate limit.

  • Length option: The 040 code sets a 4.00 m extension-cable length.
  • Armor option: The 00 code supplies the cable without stainless-steel armor.
  • Length tolerance: Extension-cable physical and electrical lengths agree within ±10%.
  • Armored alternative: The 01 option is the separate protected cable choice in the 21747 ordering table.
  • Probe lead: A 1.00 m integral lead combines with this 4.00 m extension.
  • Total path: Those two lengths produce the specified 5 m probe-to-Proximitor arrangement.
  • Proximitor: The 18745-03 is the published unit for the 5 m combined length.
  • System role: The Proximitor conditions the probe signal before it reaches the monitor.
  • Cable temperature: The 7200 probe and extension cable range is -34 to +177 °C.
  • Separate electronics limit: The 7200 Proximitor range is -51 to +100 °C.
  • Humidity: The 7200 system environmental limit is up to 95% noncondensing relative humidity.
  • Radial vibration: A complete 7200 loop can monitor shaft vibration in rotating machinery.
  • Axial position: The assembled transducer system supports thrust-position measurement.
  • Shaft position: The full 7200 system can indicate average radial shaft position.
  • Eccentricity: The complete measurement loop can measure rotor bow.
Description
Within a 7200 proximity transducer loop, 21747-040-00 is the 4.00 m unarmored extension cable between an integral probe lead and a Proximitor. It is a cable component, not a complete measuring system.

A 1.00 m probe lead and 21747-040-00 form the 5 m combined length specified for the 18745-03 Proximitor. The extension preserves the planned electrical path while allowing the Proximitor to be positioned away from the probe tip.

The unarmored construction of 21747-040-00 suits a cable route that does not require the optional stainless-steel armor. Where the route is exposed to physical abuse, the 7200 ordering table provides a separate armored cable option.

Technical notes
For 21747-040-00, the 040 option specifies 4.00 m of extension cable without armor. Bently Nevada states that physical cable length equals electrical length within ±10%; this cable forms part of a combined 5 m probe-to-Proximitor path, not a stand-alone calibrated sensor. A protected route matters because the 00 armor option adds no stainless-steel covering against physical abuse.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Will 21747-040-00 complete a 5 m 7200 loop with a 1 m probe lead?
Yes. Its 4.00 m extension length combines with a 1.00 m integral probe lead for the 5 m path specified with the 18745-03 Proximitor.
Is 21747-040-00 the armored choice for a cable route exposed to physical abuse?
No. The 00 armor option is unarmored; the 01 option in the 21747 family adds stainless-steel armor for a route needing that protection.
Can 21747-040-00 replace a 4.5 m extension cable without changing the loop?
No. Its 040 option is 4.00 m; the 045 option is 4.50 m, so the assembled electrical length changes.
Does 21747-040-00 generate the displacement output sent to a monitor?
No. It is an extension cable within the 7200 loop; the Proximitor conditions the probe signal for the monitor.
Does 21747-040-00 have the same temperature limit as the Proximitor?
No. The 7200 probe and extension cable are rated -34 to +177 °C, whereas the Proximitor has its own -51 to +100 °C operating range.
Is 21747-040-00 the specified 4 m cable for a 9 m 18745-04 system?
No. The 7200 ordering table restricts the 4.00 m option to the 18745-03 5 m Proximitor; the 9 m arrangement uses other extension lengths.
