Features

Smaller and easier to use. Perfect for recording vibrations!
・You can easily record waveforms by connecting to a vibration meter.
・It records to a CF card and can transfer to a PC.
・The system provides trigger and pre-trigger functions for recording impact waveforms.
・You can record voltage signals like vibration waveforms, with a maximum sampling rate of 400 kHz.
. You can perform frequency analysis using FFT analysis software (option).
. You can select high-speed recording and long-time recording by switching the sampling time.

• This is a compact recorder with a 4.3-inch TFT color liquid crystal display. The main body weighs about 600g, making it lightweight and easy to carry.
• It is suitable for combination with our portable vibration meter and other vibration meters.

Application example

Optimal recorder/recorder for recording vibration waveforms

Waveforms of vibration spread over a wide range, from very low frequencies such as those of buildings and ground to high frequencies such as those of high-speed spindles. MODEL-9801 is a recorder that can handle those wide bands. Furthermore, it efficiently records signals only when abnormal vibrations occur due to its trigger function.

■ Vibration of rotating machines such as motor pumps

Display an example of a blower vibration waveform in displacement mode.

You can change the time axis and voltage axis so that the vibration waveform is easy to see. It is easy to operate because you can change while checking the waveform.

■ High-frequency vibration such as abnormal bearings

Example of displaying vibration waveform with higher frequency in acceleration mode

The high-resolution TFT LCD display is very clean, allowing for precise observation of even fine waveforms. You can easily save waveforms by pressing the save button at the bottom right of the screen.

■ Acceleration waveform of drop impact.

Example of displaying the drop impact as an acceleration waveform.

This screen records the impact of packaging and the dropping of a digital camera. By setting the trigger, it captures the shock waveform at a fixed position on the screen.

Recording only when abnormal vibration occurs/Recording using trigger/pre-trigger.

Using the trigger function initiates recording when the system receives a signal with a preset level. Therefore, even if you wait for a long time, it will not waste memory.
You can put the recorder on standby and record only when abnormal vibration occurs.
You can also record the signal before applying the trigger using the pre-trigger function. This is useful for recording impacts.
The waveform below records the impact. There is a [T] mark on the left side of the upper part, but that’s when the trigger worked.
In the waveform below, we recorded the time 40ms before the trigger and 160ms after the trigger.
You can see that we efficiently recorded only the time before and after the moment the impact worked.

Display waveforms on a computer. Do a frequency analysis.

By using the wave processor that comes with the Vibro Recorder MODEL-9801, you can observe the waveforms recorded by the recorder on your computer.
The wave processor has the following features.
・Application software that realizes waveform display and CSV text conversion on a personal computer.
・XY display is possible.
・There are graphic input, comment input and template functions that support report creation.
・Multiple files can be converted to CSV data at once.
