Features

• This is a general-purpose, low-cost vibration sensor that outputs 4 to 20mA with an integrated sensor and amplifier. Furthermore, it serves as a low-cost, simple vibration monitoring sensor, which is ideal for controlling and monitoring rotating machines. Specifically, there are three types of measurements available: displacement, velocity, and acceleration.Given that the output is a 4-20mA DC, you can directly connect it to recorders, indicators, sequence circuits, etc., which simplifies the setup process. Additionally, because the sensor and amplifier are integrated, there is no need for a separate vibration meter amplifier, thus reducing equipment costs.Moreover, it is designed as a 2-wire system that includes both power supply and signal lines, and conveniently, the connection polarity does not matter. This feature enhances ease of installation and reduces the likelihood of connection errors.

  You can also use it as a vibrometer or for vibrometer purposes by connecting it to a dedicated monitor or meter relay. This versatility makes it suitable for a wide range of applications.

  Lastly, it is compatible with the MVM type of Fuji Electric Co., Ltd., ensuring that it can be integrated into existing systems that utilize components from this well-regarded manufacturer.

Furthermore, it supports evacuation standards in the event of an earthquake. Impressively, it outputs the vibration acceleration, which is obtained by synthesizing the 3-direction vector of XYZ, at a standard 4-20mA.

  Moreover, this detector is capable of outputting seismic motions ranging from 0-400 gal. To ensure accuracy, the frequency band of the detector is carefully matched to the seismic motion band. Users will benefit from its real-time output, yet they have the option to switch to peak hold output if needed.

  Additionally, this is a waterproof type, complete with mounting feet, which simplifies the process of grounding. This thoughtful design ensures durability and ease of installation, making it a reliable choice for monitoring seismic activity and protecting infrastructure.

Application example

(1) If the mass of the rotating body lacks uniformity with respect to the rotating shaft, resulting in an imbalance, it will exert centrifugal force, which can cause damage to bearings, rotors, holding structures, etc.

(2) There are many causes of unbalanced vibration, such as rotor eccentricity, unevenness, and deflection. In addition, unbalance may occur due to corrosion, wear, deposits, etc. due to aging. In grinders and the like, dressers and grinding cause its imbalance.

(3) A field balancer can correct the balance while the rotor is attached, saving a significant amount of money and time compared to disassembling the machine and using a stationary balancing machine.

(4) The variation in the mass of the rotating body results in one heavy spot (two in the two-plane balance correction method) due to vector synthesis of the imbalance causes. Balancing efficiently involves determining the location and amount of that heavy spot.

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.
