Vibration switches are switches that detect the range of vibration oscillation to which they are exposed.
In some devices, excessive vibration will cause irreparable damage to the device.
The best examples in this regard are turbochargers.
If excessive vibration occurs during the compaction process, the device must be stopped immediately, otherwise the turbine will become overspeed and the blades will be damaged.
As a result of preventing this event, vibration switches can be used on specific parts of the body so that if the setpoint limit is increased, the trip device will be turned off and off.

At present in industries such as research and development, the ability to monitor, measure as well as vibrate analysis is very important.
Unfortunately, the proper techniques for building a measurement system for accurate and repetitive vibration are not always clear to researchers with the help of vibration testing and analysis tools.
Vibration switches
There are some challenges when measuring vibration, including selecting the right component, system configuration, signal ventilation, waveform analysis, and commissioning.
The vibration sensor is also called a piezoelectric sensor.
These sensors are flexible devices used to measure various processes.
This sensor uses piezoelectric effects to measure changes in acceleration, pressure, temperature and force.
The principle of operation of the vibration sensor is a sensor that operates based on different optical principles or mechanically to detect system vibrations.

The sensitivity of these sensors typically varies from 10 mV to 100 mV / g, and there are lower and higher sensitivities.
Sensor sensitivity can be selected based on the program.
Therefore, it is necessary to know the level of vibration amplitude at which the sensor is exposed to the size.

The vibration switch is a simple protection device that senses vibration and shuts off the device if it vibrates more than a predetermined threshold level.
The vibration switch can vibrate due to errors such as imbalance, misuse, loosening, worn bearings, cracked gears or lack of lubrication.
