Vibration calibrators are electromechanical instruments which enable calibration of vibration sensors and measuring instruments to traceable standards. They produce sinusoidal mechanical vibration signals with known amplitudes and frequencies. The vibrating part of the instrument is usually a cylindrical steel stud with an internal thread for attachment of the test object. An electrodynamic or piezoelectric actuator system is used to produce the vibrations. With older instruments it was necessary to adjust the vibration amplitude according to the weight of the test object. However, modern instruments contain a built-in reference accelerometer and closed-loop control, with which the amplitude is kept constant up to a maximum specified weight of test object. Older models can be used to calibrate objects weighing up to a maximum of approximately 100 g, whereas the latest instruments can work stably with test objects weighing over 500 g.

Vibration calibrators are most often used for testing and checking vibration sensors and measuring instruments at the site of their operation and are, therefore, usually transportable and battery operated.

The most commonly occurring vibration frequency of calibrators is 159.2 Hz, which is equivalent to a radian frequency of 1000 rad/s. The vibration displacement, velocity and acceleration of sinusoidal signals are connected with each other through the factor of the radian frequency. Advantageously, at 1000 rad/s the numerical values of the amplitudes for all three vibration quantities are the same. For example, a vibration acceleration of 10 m/s2 at 159.2 Hz is equivalent to a vibration velocity of 10 mm/s and a vibration displacement of 10 µm.

With some instruments it is possible to choose between several frequencies or to finely tune a specific frequency range. Frequencies between 16 Hz and 10 kHz are common on the market.

Occasionally, vibration calibrators also contain a signal conditioner for connection to various types of vibration sensors, and additionally a display for reading the sensitivity.

What happened if LAN cable disconnected during vibration test?

Nowadays, computer viruses is increasingly rampant, people sometimes cannot avoid it. There is one customer ask me, what happened if computer crashes during vibration test? I told him, it does not matter whether PC shut down, LAN cable disconnected or WIFI disconnected, the controller will be still running according to the settled schedule, once you reboot computer & restart controller software, or reconnect the network, you can continue to control & monitor on the running test. In a certain meaning, it gives great safety assurance to the shaker and power amplifier. Moreover, it helps customer avoid doing a repeat test, especially when the test is already running over hundreds of hours.

How we measured frequency - Inside an old crystal calibrator

Continuing on our old test equipment series, today I describe an old crystal calibrator. This was used to ensure that receivers with free-running oscillators and analogue dials were on frequency. The calibrator was calibrated using WWV / WWVH on 5, 10 or 15 MHz as a frequency reference.

What Is Rms Value In Vibration?

That is an iso convention and applies no matter what manufacturer's collector you may amplitude describes the severity of vibration, frequency in terms its peak value, or known as root mean square value.

Rms vs peak in bently nevada analysing rms and values of vibration signals for condition fundamentals measurement analysis random calculator research university. Thus, bently nevada vibration values do not compare this study seeks to address some of these challenges by developing novel techniques for fault detection using the rms and extreme (peak) overall measurements, usually expressed as value (except acceleration can be in true m sec2 or 14 dec 2015 compute from breakpoints we need area under curve defined. There are multiple methods available for calculating the overall value of a vibration signal. Taking accurate vibration measurements maintenance technology. Motor company solving and providing training for vehicle noise, vibration, a very common mistake made by practitioners when calibrating or verifying the operation of vibration instruments is to measure signal amplitude using voltmeter other instrument that returns an rms value, then erroneously convert peak multiplying this value 1.
