      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/50M 133442-01 is the documented two-channel tachometer i/o module for the 50M product family.
      • Accepts proximity-probe or magnetic-pickup speed signals.
      • Supports speed, rotor acceleration and direction measurements.
      • Provides 4-20 mA recorder outputs and buffered transducer access.
      • Operates as a monitoring tachometer and not as an overspeed-protection or speed-control device.

      Install 3500/50M 133442-01 only with the documented 50M front/rear module, termination hardware, transducers and approved 3500 rack configuration. Commissioning covers identity, signal path, scaling, alarms and controlled response.

      Important Notice: Confirm the complete 3500/50M 133442-01 identity, installed interfaces, approved configuration and final functional acceptance record before service release.

      Bently Nevada 3500/50M 133442-01 Technical Reference (PDF)Bently Nevada 3500/50M 133442-01 Official Datasheet (PDF)

      Important Notice: The first document is an exact-model technical reference. The second is the unmodified official manufacturer family datasheet used for installation limits and technical evidence.

      Machine speed indication
      Measure rotational speed from a compatible proximity probe or magnetic pickup.
      Rotor acceleration
      Calculate acceleration using the documented events-per-revolution configuration.
      Direction measurement
      Use the correct paired input arrangement for rotational direction.
      Zero-speed observation
      Use a suitable proximity input; magnetic pickups are not appropriate at zero speed.
      Read the applicable Bently Nevada installation instructions before work. Verify 3500/50M 133442-01, its installed system arrangement and configured interfaces before commissioning.
      1
      Confirm 133442-01 is the internal-termination I/O module and retain the matching front tachometer monitor.
      2
      Match the selected transducer type and input polarity to the installed channel.
      3
      Do not use the 3500/50M as the machine overspeed protection or speed-control loop.
      4
      Do not rely on a magnetic pickup for reverse or zero-speed detection.
      5
      Set events per revolution from the actual target geometry.
      6
      Verify input frequency and reported speed through a controlled rotation test.
      7
      Check 4-20 mA scaling and external load before accepting the recorder output.
      8
      Record speed, direction, acceleration and channel diagnostic results before service release.

      FAQS

      • What hardware role does 3500/50M 133442-01 have in a 3500/50M tachometer assembly?
        133442-01 is the rear I/O module with internal terminations; the complete tachometer channel also uses the matching front monitor and transducers.
      • Which transducers may feed 3500/50M 133442-01?
        The tachometer accepts proximity-probe or magnetic-pickup inputs when the selected channel configuration and signal envelope match.
      • Why must 3500/50M 133442-01 not be assigned to overspeed protection?
        The datasheet explicitly excludes the 3500/50M from overspeed-protection and closed-loop speed-control service.
      • Can a magnetic pickup on 3500/50M 133442-01 prove reverse or zero-speed operation?
        No. Magnetic pickups require motion-generated voltage and are not suitable for reverse or zero-speed detection in this application.
      • How is target geometry represented in the setup for 3500/50M 133442-01?
        Configure events per revolution from the actual target: 1-255 for acceleration/zero-speed and 0.0039-255 for other measurements.
      • What maximum speed-processing limits should be checked for 3500/50M 133442-01?
        The monitor supports up to 99,999 rpm indication and a maximum input frequency of 20 kHz, subject to target configuration.
      • What recorder-output test applies after installing 3500/50M 133442-01?
        Verify 4-20 mA scaling with a 0-600 Ohm load and confirm the update response is 100 ms or less.
      • Which acceptance results should be retained for 3500/50M 133442-01?
        Record transducer type, target events per revolution, speed, direction, acceleration, channel diagnostics and recorder-output response.
