More Information

Overview Manuals High-Temp Cable Differential Expansion Signal Integrity Installation Limits

Features:

  • The cable provides a 4.0 m signal route between a 25 mm probe lead and Proximitor Sensor.
  • High-temperature FluidLoc construction uses PFA insulation without stainless-steel armor.
  • The selected 05 suffix applies the system's multiple-approval cable configuration.
The 330854 family belongs to the separate-probe 25 mm system used for extended differential-expansion range.

Over its 4.0 m length, the triaxial cable maintains defined resistance in both the center and jacket conductors.

Connector material combines gold-plated brass and beryllium copper at the removable coaxial joint.

The Bently Nevada 330854-040-24-05 3300 XL 25 mm Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

PFA-Insulated FluidLoc Construction

  • Temperature class: The extension cable operates and stores from -35 to +200 deg C.
  • Insulation: PFA surrounds the 75-ohm triaxial cable used by the 25 mm system.
  • Fluid barrier: Option 24 applies high-temperature FluidLoc construction.
  • Armor boundary: The 24 option is unarmored; flexible stainless-steel armor belongs to option 25.

Position in the 25 mm Measurement Chain

  • Probe side: One connector receives the response from the separate 25 mm proximity probe.
  • Electronics side: The opposite connector presents that response to the 25 mm Proximitor Sensor.
  • System purpose: The connected system measures differential expansion between turbine rotor and casing growth.
  • Length check: Probe lead and extension cable are selected together for a 5 m or 9 m total system.

Conductor Values Across Four Metres

  • Core path: Center-to-center resistance is 1.0 ±0.25 ohms.
  • Shield path: Coaxial conductor resistance is 0.3 ±0.1 ohms.
  • Capacitive load: Distributed capacitance is 69.9 pF/m typical.
  • Contact surfaces: Gold-plated brass and beryllium copper form the connector contacts.

Routing and Connector Controls

  • Bend radius: Route the cable with at least a 25.4 mm radius.
  • Joint assembly: Connector-to-connector tightening is finger-tight.
  • Torque ceiling: The coaxial joint must remain below 0.565 N-m.
  • Approval selection: The final 05 field identifies the multiple-approval configuration.
Description
Within a 3300 XL 25 mm transducer system, Bently Nevada 330854-040-24-05 is the 4.0 m high-temperature extension cable that links the separate probe to the Proximitor Sensor used for differential-expansion measurement.

PFA insulation and FluidLoc construction let 330854-040-24-05 carry the triaxial probe signal through temperatures up to 200 deg C without the flexible stainless-steel armor selected by cable option 25.

Electrical continuity through 330854-040-24-05 is divided between the center conductor and coaxial jacket, with cable capacitance distributed along the 4.0 m route before the signal enters the conditioning electronics.

The probe lead and 330854-040-24-05 must add to the total system length configured at the Proximitor Sensor; the final 05 suffix applies the documented multiple-approval selection.

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.
How does option 24 define 330854-040-24-05?
On 330854-040-24-05, code 24 selects an unarmored high-temperature FluidLoc cable with PFA insulation.
Why is 330854-040-24-05 not an 11 mm extension cable?
The base number 330854 places 330854-040-24-05 in the 3300 XL 25 mm transducer system, not the 330730 11 mm cable family.
Which temperature boundary applies specifically to 330854-040-24-05?
The extension cable in 330854-040-24-05 is specified for operation and storage from -35 to +200 deg C.
Where should 330854-040-24-05 be connected?
Install 330854-040-24-05 between the separate 25 mm probe lead and the matching 3300 XL 25 mm Proximitor Sensor.
What must be matched when selecting 330854-040-24-05 for an existing chain?
The 4.0 m length of 330854-040-24-05 plus the probe lead must equal the 5 m or 9 m total length selected on the Proximitor Sensor.
Does 330854-040-24-05 include multiple approvals?
Yes. The final 05 ordering field in 330854-040-24-05 is the multiple-approval option.
