      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Bently Nevada 330851-04-000-015-10-01-05 positions the sensing face in a smooth-case mounting while the lead leaves sideways. Its minimum-length side-exit body supports installations with limited axial clearance around a turbine collar.
      Case geometry: 1.06 in diameter, 1.5 in overall length
      Cable arrangement: Side exit, 1.0 m lead with SST armour
      Matched response: 0.787 V/mm nominal scale factor
      The smooth case is 1.06 in in diameter and 1.5 in long, with a side-exit lead and zero unthreaded-length selection. It uses a clamp or adapter suitable for the smooth body instead of a threaded mounting hole. The PEEK sensing tip and AISI 304 stainless-steel case are combined with a 75 Ω triaxial FluidLoc lead and stainless-steel armour.

      The 1.0 m probe lead combines with a matching 4.0 m or 8.0 m extension cable and the corresponding 5 m or 9 m 3300 XL 25 mm Proximitor Sensor. Its isolated centre-to-outer-conductor resistance is 6.2 ± 0.5 Ω. Armour protects the cable mechanically but does not remove the need for proper support, connector protection or the 25.4 mm minimum bend radius.

      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 smooth-case retention, side-exit cable support, electrical matching and displacement checks.
      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 330851-04-000-015-10-01-05 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.

      Secure the smooth case

      Use the correct clamp or adapter; do not transfer threaded-case torque values to this smooth body. 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

      • Does 330851-04-000-015-10-01-05 screw into an M30 mounting hole?
        No. Its case is smooth, 1.06 in in diameter, with a side-exit lead. It needs a suitable smooth-case mounting or clamp arrangement rather than an M30 thread.
      • Why is 1.5 in an important case length for 330851-04-000-015-10-01-05?
        The 015 selection is a 1.5 in overall case, the minimum for the side-exit case type. The 000 unthreaded-length field is the required zero selection for a smooth case; it does not create a threaded portion.
      • What routing advantage does the side exit of 330851-04-000-015-10-01-05 provide?
        The lead leaves through the side of the smooth case, allowing routing away from the rear axis. Check radial clearance, support and the 25.4 mm minimum cable bend radius around the actual mounting.
      • Does the stainless-steel armour on 330851-04-000-015-10-01-05 permit pulling on the cable during installation?
        No. Armour provides mechanical protection but is not a pulling or mounting attachment. Support the lead and keep tension away from the side exit and connector.
      • Which torque limit applies to the electrical connector of 330851-04-000-015-10-01-05?
        Make the connector joint finger tight and do not exceed 0.565 N·m. Threaded probe-body torque values do not apply to this smooth case or its electrical connection.
      • How does 330851-04-000-015-10-01-05 achieve a nine-metre calibrated measurement chain?
        Use the 1.0 m probe with the appropriate 8.0 m extension and 9 m 3300 XL 25 mm Proximitor Sensor. Confirm all components belong to the matching transducer system.
      • What remains to be checked before using 330851-04-000-015-10-01-05 in an approved-area installation?
        The 05 option selects multiple approvals. Check the supplied unit markings, associated apparatus and installation drawings against the actual area requirements; the selection alone does not approve every system arrangement.
      • What distinguishes a clamp problem from an electrical fault when testing 330851-04-000-015-10-01-05?
        Compare controlled target movement with output while observing that the smooth case remains fixed. If the case slips, correct its support first; if it stays fixed, inspect continuity, connectors, electrical length and target calibration.
