      Information

      Information

      Overview Manuals Common Applications Product Precautions
      This sensor configuration converts casing or bearing-housing motion into a conditioned velocity signal for continuous machinery-condition assessment.
      • Measures absolute vibration at the machine housing or structural mounting point
      • Uses solid-state integrated electronics with no moving sensing parts
      • Permits vertical, horizontal or other approved mounting orientation
      • Provides a case-isolated dynamic velocity signal for monitoring

      Mount 330500-04-00 firmly on the bearing housing or machine casing using the supplied 1/4-20 UNC adaptor and the documented torque range. Confirm cable loading, case isolation and signal polarity before accepting the vibration channel.

      Important Notice: Confirm the complete 330500-04-00 code, 1/4-20 UNC adaptor, mounting surface, torque, 2-pin connector, case isolation, polarity, cable loading, monitor input and controlled vibration response before commissioning.

      Apter Power 330500-04-00 Manuals and Guides

      The first document is a model-specific engineering data reference. The second is a distinct installation and commissioning workbook with field checks and acceptance records.

      Bearing-housing vibration protection
      Measures transmitted casing vibration where rotor motion reaches the bearing housing.
      Machine-casing condition trending
      Supplies a velocity signal for detecting changes associated with imbalance or misalignment.
      Structural vibration assessment
      Supports measurement on a rigid structural point selected for meaningful machine response.
      Generator stator-frame monitoring
      Can support documented Velomitor measurements on generator frame or core structures.
      Read the applicable Bently Nevada installation information before work. Verify 330500-04-00 and the installed Velomitor Piezo-velocity Sensor configuration before isolation, wiring or commissioning.
      1
      Confirm the full 330500-04-00 order code and 1/4-20 UNC adaptor.
      2
      De-energize the monitoring input before connecting or removing the sensor cable.
      3
      Prepare a clean, flat and rigid mounting surface on the housing or casing.
      4
      Tighten the mounting interface within the documented torque range.
      5
      Keep the case-isolated wiring arrangement intact and avoid ground loops.
      6
      Verify Pin A and Pin B polarity before channel configuration.
      7
      Check cable length and input compatibility with the selected monitor.
      8
      Compare the restored vibration response with a controlled reference or known baseline.

      FAQS

      • What does the -04 mounting option specify on 330500-04-00?
        It specifies a 1/4-20 UNC mounting-thread adaptor.
      • What does the final -00 code indicate for 330500-04-00?
        The official ordering table identifies -00 as agency approval not required.
      • What physical quantity does 330500-04-00 measure?
        It measures absolute vibration of a bearing housing, machine casing or structural mounting point.
      • Can 330500-04-00 be installed in different orientations?
        The sensor can be mounted vertically, horizontally or at another suitable angle when the mounting surface and signal direction are engineered correctly.
      • What connector is used by 330500-04-00?
        The datasheet specifies a hermetically sealed 2-pin MIL-C-5015 connector.
      • Why is mounting quality important for 330500-04-00?
        Poor mounting can reduce amplitude and frequency response or create signals that do not represent machine vibration.
      • How should polarity be verified on 330500-04-00?
        When case motion is toward the connector, Pin A should become positive relative to Pin B.
      • What should be checked after replacing 330500-04-00?
        Verify mounting torque, cable condition, case isolation, channel bias and the measured response against a baseline.
