Acoustic Vibration Portable Data Recorder
DR-7100

You want to thoroughly investigate every sound or vibration that may be causing a problem. However, the measurement site may be a delivery destination, or a cramped or elevated location. When you cannot take the time to settle in and record data, you also want to reduce setup time. In such situations, the convenient features of the DR-7100 Acoustic Vibration Portable Data Recorder come in handy.

For example,
●Want to calibrate quickly ⇒ [TEDS calibration key] prevents setting errors
●Want to record only the problem phenomenon ⇒ One-touch [Trigger Key] (pre-trigger capable)
●Want to check recorded data on the spot ⇒ [RECALL Key] switches immediately to playback mode

Features

  • High-speed ・ High-precision data recording (4ch 40 kHz range 24-bit) ※

  • Equipped with dedicated input for rotational pulse 1ch

  • SDHC 32 GB compatible

  • Reduction of setting time, TEDS sensor compatible.

  • A5 size

  • 2 enclosure synchronization function (optional)

* The 40 kHz range is optional (the standard is 20 kHz bandwidth).

Animation example

Operational animation example using the DR-7100 4-channel Acoustic Vibration Portable Data Recorder

1. Data recording

To shorten the recording time, we will connect two DR-7100 devices in sync (8-channel) for data recording.

  • 8 ch synchronization state of DR-7100
    8 ch synchronous state of DR-7100
    (when unit sync options DR-0730, DR-0703 are installed)

    Used sensors: Built-in preamplifier type accelerometer
    (NP-3578N10: 2 units, NP-3211: 1 unit)

    ※ Operations are performed on the master side DR-7100.
  • 1ch: Vibration data recorded from the reference point (red circle). 2 to 7ch: Vibration from measurement points (in three axial directions).
    1ch: Vibration data of the reference point (red circle) is recorded
    2 to 7ch: Vibration data of measurement points (in 3-axis directions) is recorded at two locations each

    ※ A total of 58 points (174 pieces) of data will be recorded (30 seconds each point).
    ※ Even with data recorded from one unit, actual operation animation is possible.
