Vibration Sensor & accelerometer

Since all material objects that have mass are also capable of vibration, and in a way, all objects around us will be able to vibrate. In fact, in industrial engineering designs, this parameter should not be overlooked by a skilled engineer, especially in the performance and efficiency of rotating equipment.

In maintenance operations as well as troubleshooting rotating equipment such as electric motors, pumps and turbines, etc., it is necessary to monitor the vibration and vibration status of the equipment, which can be done by vibration and acceleration sensors. By using the appropriate sensor to provide critical operational information, the device operates in a more secure manner and personnel prevent irreparable damage before the device reaches a critical condition.

In practice, the vibration parameter includes displacement, frequency, acceleration and velocity, which in practice vibration sensors include the output that represents one of these parameters.

Depending on the operating conditions of the equipment and temperature conditions, etc., one of these types of vibration and acceleration, speed, frequency or displacement sensors should be used.

Also, different mechanisms are used in the construction of these sensors, some of which are mentioned below.
