BENTLY 128229-01  振动监测器

BENTLY振动监测器作为国家标准已实施三年,振动监测器作为技防手段已逐步被人们认识和应用。

振动监测器是一种对重要设备的振动频率进行高精度监测的仪器。

该款产品可对精密设备 (例: ATM机，精密机床等设备)进行24小时不间断监控如果设备的振动频率超出正常范围，那么振动监测器就可以立刻发出警报，使用户将损失降至Zu低，从原理上进，振动监测器与早期的震动传感器有些类似，都是通过收集一些振动波形的能量，再转化为电量进行判别。如果传送的电量超过一定范围，那么振动监测器就会认为是振动波形出现了问题，从而自动发出报警。

但是传统的震动传感器由于判别不够精确，因此经常发生一些误报或者不报的现象。再加上某些行业市场还不太规范 (特别是ATM监控市场)

产品鱼龙混杂，以次充好，以假乱真，给用户在选购时带来一定的困难

为此，这里专门针对真假震动监护器做一些基本的分析。

真正的震动监护器能够实时监测到任何震动波形

它能够以一定的频率采集不同方向的震动数据

高性能的震动监测器能够以千分之一秒的速度采集不同三个方向的震动数据

也即每隔1毫秒采集一次震动数据进行判断或显示或记录。

而假的震动传感器一般是通过固定在一根弹上的铁锤的晃动来感应震动信号

当震动到一定幅度时，铁锤碰到旁边的金属片，形成一次闭路电流，从而判断出发生一次震动，这种震动从原理上来看很容易错过很多破坏性的震动，

并目容易产生误报，更谈不上采集震动数据了

还有一些假震动传感器将弹和铁锤小型化后封装到一个集成电路中，但不管它采取哪种形式都不能采集到震动数据，这是真假震动传感器的zui本质区别。

BENTLY vibration monitor as a national standard has been implemented for three years, vibration monitor as a means of technical prevention has been gradually recognized and applied.

Vibration monitor is a kind of instrument to monitor the vibration frequency of important equipment with high precision.

This product can be used for precision equipment (e.g. : ATM machine, precision machine tools and other equipment) for 24 hours of continuous monitoring if the vibration frequency of the equipment is out of the normal range, then the vibration monitor can immediately issue an alarm, the user will reduce the loss to a low, in principle, the vibration monitor and early vibration sensors are similar, are by collecting some vibration waveform energy, Then it is converted into electricity for discrimination. If the amount of power transmitted exceeds a certain range, the vibration monitor will think that there is a problem with the vibration waveform, and automatically issue an alarm.

However, because the traditional vibration sensor is not accurate enough, some false positives or non-positives often occur. In addition, some industry markets are not well regulated (especially the ATM monitoring market).

Products mixed, shoddy, fake and real, to users in the purchase of a certain difficulty

For this reason, here is dedicated to the true and false vibration monitor to do some basic analysis.

A true vibration monitor can detect any vibration waveform in real time

It can collect vibration data in different directions at a certain frequency

The high-performance vibration monitor can collect vibration data in three different directions at a speed of one thousandth of a second

That is, the vibration data is collected every 1 millisecond for judgment or display or record.

Fake vibration sensors, on the other hand, usually detect vibrations by the shake of a hammer attached to a projectile

When the vibration reaches a certain amplitude, the hammer hits the metal sheet next to it, forming a closed circuit current, which determines the occurrence of a vibration, which is easy to miss a lot of destructive vibration from the principle.

It is easy to generate false positives, let alone collect vibration data

There are also some false vibration sensors that encapsulate the bomb and hammer into an integrated circuit after miniaturization, but no matter what form it takes, it can not collect vibration data, which is the essential difference between true and false vibration sensors.
