      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Within a matched NSv system, Bently Nevada 330980-70-05 supports small-target measurements on fluid-film-bearing machines. It conditions the probe signal for the receiving monitor where mounting clearance is limited.
      System configuration: 7.0 m electrical length, panel mount
      Field connection: SpringLoc terminals and 50 ohm output resistance
      Nominal NSv system scale factor: 7.87 V/mm (200 mV/mil)
      The panel-mounted sensor accepts one compatible 3300 RAM or NSv probe and extension cable, with the combined electrical length matched to its 7.0 m calibration. SpringLoc terminals connect the field wiring without special installation tools, while the probe remains at the shaft measurement point.

      A matched NSv system provides a 1.5 mm linear measurement range and a nominal scale factor of 7.87 V/mm. The recommended probe gap is 1.0 mm; the specified response depends on the matched components and calibration target, including the standard AISI 4140 steel target. The Proximitor operating-temperature upper limit is +100 °C, lower than that of the probe and extension cable.

      A compatible 3300 RAM installation can retain its probe and extension cable when converted to an NSv Proximitor with the correct electrical length. Conversion from a 3000-series or 7000-series 190 system instead requires the probe, extension cable and Proximitor to be replaced together with NSv components. These are different upgrade paths and do not make individual 190-series components interchangeable with this sensor.
      Controller platform reference: Bently Nevada 3300 XL NSv transducer system. Follow NSv installation instructions and approved drawings.
      Technical resources for Bently Nevada 330980-70-05 cover NSv system specifications and sensor configuration. Use the original datasheet excerpt alongside the separate field guide for connection checks and commissioning.
      The manufacturer excerpt retains original pages. The separate Apter Power guide supports field verification; follow the applicable NSv installation instructions and approved system design.
      System and supply context: Bently Nevada 330980-70-05 is the 7 m, panel-mounted conditioner in a 3300 XL NSv transducer chain. Compatible probe and cable selection must match the sensor calibration. Probes, extension cables, barriers and monitors are included only when itemized in the quotation.

      System applications: The following uses describe the complete NSv measurement system. Confirm the target, probe arrangement and receiving monitor function before selecting the sensor for a channel.
      Apply these checks to Bently Nevada 330980-70-05 and its matched NSv monitoring channel before returning the machine to service.
      Preserve the 7 m calibration

      Check total probe and extension-cable length. Do not substitute a 5 m chain while retaining this 7 m sensor.

      Verify negative supply voltage

      Measure the supply at the sensor. Apply the barrier-specific voltage range and account for reduced linear range above -23.5 V DC.

      Use the panel-mount arrangement

      Inspect the panel pad and fasteners, and secure the sensor without loading the coaxial connector or field conductors.

      Keep field wiring correctly assigned

      Use suitable shielded conductors within the SpringLoc wire-size range. Check supply, common and signal connections before energizing.

      Respect sensor temperature limits

      Keep the sensor within -52 to +100 °C in operation. The hotter probe/cable rating does not apply to the conditioner.

      Verify the complete measurement loop

      Check target material, probe gap and signal response. Confirm monitor indication and the required protection-channel functions after installation.

      Technical notes

      Electrical-length matching: The 70 option selects a 7.0 m system with panel mounting. The probe lead plus any extension cable must total 7.0 m; sensor-to-monitor field wiring is separate from this calibrated length.

      Power and measurement limits: Use -17.5 to -26 V DC without barriers or -23 to -26 V DC with barriers. Supply more positive than -23.5 V DC can reduce linear range. System performance reference conditions are 0 to +45 °C, -24 V DC supply, 10 kΩ load, an AISI 4140 steel target at least 31 mm in diameter, and a 1.0 mm probe gap.

      FAQ View All FAQ

      • Why can the output range of 330980-70-05 shrink even when the supply is within its operating range?
        The sensor accepts -17.5 to -26 V DC without barriers, but a supply more positive than -23.5 V DC can reduce the linear measurement range. With barriers, use -23 to -26 V DC and verify the voltage at the sensor terminals.
      • How far can the monitor be located from 330980-70-05?
        The maximum field-wiring length is 305 m between the Proximitor Sensor and the monitor. Use three-conductor shielded cable and account for high-frequency signal rolloff on long runs. This field wiring is separate from the 7.0 m probe-and-extension electrical length.
      • Can 330980-70-05 retain a 3300 RAM probe during an NSv upgrade?
        The NSv Proximitor Sensor accepts a compatible 3300 RAM probe and extension cable. Retention requires the correct 7.0 m total length and verification of the complete measurement channel. Upgrades from a 3000-series or 7000-series 190 system require replacement of the probe, extension cable and Proximitor Sensor with NSv components.
      • Which probe-and-extension combinations suit the 7 m calibration of 330980-70-05?
        A 1.0 m NSv probe cable with a 6.0 m extension, or a 0.5 m probe cable with a 6.5 m extension, provides the required 7.0 m total electrical length. A 7.0 m probe cable can connect without an extension. Match the probe family and system calibration as well as length.
      • Does 330980-70-05 use a panel pad or a DIN-rail mounting option?
        The 70 option selects a 7.0 m system with panel mounting. A 7 m DIN-mounted configuration uses option 71, so the mounting arrangement must be checked separately from the shared system length.
      • What target and gap should be used when checking 330980-70-05 calibration?
        Use the matched NSv probe and cable with an AISI 4140 steel target at least 31 mm in diameter, a 1.0 mm probe gap, a -24 V DC supply and a 10 kΩ load, with the transducer components between 0 and +45 °C. These are the reference conditions for the nominal 7.87 V/mm system scale factor; another target material or test condition can change the response.
      • Which wire sizes fit the SpringLoc terminals on 330980-70-05?
        The field-wiring range is 0.2 to 1.5 mm². When ferrules are fitted, use 0.25 to 0.75 mm² conductors. Keep the terminal assignment and shield arrangement consistent with the installed monitoring circuit.
      • Can 330980-70-05 be mounted in the same hot zone as an NSv probe?
        The Proximitor Sensor operates from -52 to +100 °C and stores from -52 to +105 °C. Its upper operating limit is lower than the probe and extension-cable limit of +177 °C, so locate the sensor according to its own temperature rating.
