Information

Overview Downloads Applications / Compatibility Product Precautions
  • Bently Nevada 330851-02-000-060-10-00-CN places a threaded sensing body at the turbine collar while its short lead connects to a separately selected extension. The installation combines 60 mm mechanical reach with the electrical length required by the remote conditioner.
Case interface: M30×2 threaded construction
Integral lead: 1.0 m unarmored FluidLoc cable
Matched-system output: 0.787 V/mm nominal
The M30×2 probe has a 60 mm overall case length, a zero unthreaded-length selection and a 1.0 m total lead. The selected 00 armor option uses an unarmored lead. PEEK forms the probe tip, AISI 304 stainless steel forms the case, and the 75 Ω triaxial FluidLoc cable uses PFA insulation.

The 1 m probe lead combines with the appropriate 4 m or 8 m extension cable to form a 5 m or 9 m system using the matching 3300 XL 25 mm Proximitor Sensor. Disconnected probe resistance from center to outer conductor is 6.2 ± 0.5 Ω. Cable and conditioner selection must preserve the complete electrical length.

For the complete matched system, nominal sensitivity is 0.787 V/mm and the linear range is 12.7 mm. The reference conditions include a -24 Vdc supply, a 10 kΩ load, a Bently Nevada AISI 4140 steel target at least 61 mm in diameter, a 7 mm gap and component temperatures from 0 to +45 °C. Probe survivability to +200 °C does not make these reference accuracy conditions universal.
Controller platform reference: 3300 XL 25 mm system. Match electrical length and target calibration.
Original Bently Nevada pages explain the 25 mm sensing system, calibrated response, materials and applicable cable options. The separate installation guide covers mechanical and thermal placement, connector protection and displacement verification.
Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
System and supply context: This 1.0 m probe is one component of the 3300 XL 25 mm transducer chain. The Proximitor Sensor, any required extension cable, brackets and monitor are separate unless itemized.

Application scope: Differential-expansion performance depends on the collar or ramp geometry, target material and configured channel arrangement. Mechanical fit alone does not establish electrical or calibration compatibility.
Prepare Bently Nevada 330851-02-000-060-10-00-CN for its configured installation using these checks.
Preserve electrical length

The 1 m probe lead combines with the appropriate 4 m or 8 m extension cable to form a 5 m or 9 m system using the matching 3300 XL 25 mm Proximitor Sensor.

Protect the connector

Keep the high-temperature ClickLoc connector clean, finger tight and inside its connector protector.

Check target geometry

Use the intended collar or ramp surface and verify the target material against the calibration.

Separate torque limits

Do not apply probe-body tightening torque to the electrical connector; connector maximum is 0.565 N·m.

Observe thermal boundaries

Apply probe, cable and Proximitor Sensor temperature limits separately; avoid treating short-term exposure as continuous service.

Verify motion response

Test the complete channel through controlled relative movement before restoring the machine protection function.

Technical notes

Electrical relationship: The 1 m probe lead combines with the appropriate 4 m or 8 m extension cable to form a 5 m or 9 m system using the matching 3300 XL 25 mm Proximitor Sensor. Disconnected probe resistance from center to outer conductor is 6.2 ± 0.5 Ω. Cable and conditioner selection must preserve the complete electrical length.

Measurement boundary: For the complete matched system, nominal sensitivity is 0.787 V/mm and the linear range is 12.7 mm. The reference conditions include a -24 Vdc supply, a 10 kΩ load, a Bently Nevada AISI 4140 steel target at least 61 mm in diameter, a 7 mm gap and component temperatures from 0 to +45 °C. Probe survivability to +200 °C does not make these reference accuracy conditions universal.

FAQ View All FAQ

  • How does 330851-02-000-060-10-00-CN connect a one-metre probe to a five-metre system?
    Combine the 1.0 m probe lead with the matching 4.0 m extension cable and 5 m 3300 XL 25 mm Proximitor Sensor. The cable lengths form the calibrated chain; the 60 mm case is a separate mechanical dimension.
  • Which clearance matters when positioning the 60 mm body of 330851-02-000-060-10-00-CN?
    Check M30×2 thread engagement, target gap and clearance behind the case for the lead. The 000 selection gives zero unthreaded length, while the sensing gap is set relative to the target independently.
  • Why can a steel target of the wrong grade change the response of 330851-02-000-060-10-00-CN?
    Standard system calibration uses Bently Nevada AISI 4140 steel. A different material can change the eddy-current response, so the stated scale factor and accuracy must not be transferred without the appropriate calibration.
  • Does the 25 mm sensing tip of 330851-02-000-060-10-00-CN require a larger flat target?
    Yes. The reference flat target is at least 61 mm in diameter. Confirm the collar surface and surrounding clearance before applying the nominal matched-system performance.
  • How can moisture protection be maintained around the lead joint of 330851-02-000-060-10-00-CN?
    Keep the ClickLoc joint clean and fit its connector protector. FluidLoc cable and front/rear probe seals reduce moisture migration; the protected system remains non-submersible.
  • Which reading should an isolated continuity check of 330851-02-000-060-10-00-CN produce?
    The 1.0 m probe has 6.2 ± 0.5 Ω resistance from centre to outer conductor. Measure it separately from the extension cable so the additional cable resistance does not obscure the probe result.
  • Can the high-temperature probe rating of 330851-02-000-060-10-00-CN be applied to its remote conditioner?
    No. The probe operates from -35 to +200 °C, whereas the Proximitor Sensor operates from -51 to +100 °C. Place each component within its own temperature limits.
  • What confirms the correct signal direction after fitting 330851-02-000-060-10-00-CN?
    Move the target or probe mounting by a known amount and compare the output and monitor indication. Verify the configured collar geometry and channel direction before restoring the protection function.
