Vibration Sensor Working and Applications

At present in the industry like research and development, the ability of monitoring, measuring as well as analyzing the vibration is very important. Unfortunately, the suitable techniques for making a measurement system for vibration with precise & repeatable are not always clear to researchers with the shades of test tools & analysis of vibration. There are some challenges related while measuring the vibration which includes a selection of suitable component, the configuration of the system, signal conditioning, analysis of waveform and setup. This article discusses what is a vibration sensor, working principle, types, and applications

What is a Vibration Sensor?

The vibration sensor is also called a piezoelectric sensor. These sensors are flexible devices which are used for measuring various processes. This sensor uses the piezoelectric effects while measuring the changes within acceleration, pressure, temperature, force otherwise strain by changing to an electrical charge. This sensor is also used for deciding fragrances within the air by immediately measuring capacitance as well as quality.

Vibration Sensor Working Principle

The working principle of vibration sensor is a sensor which operates based on different optical otherwise mechanical principles for detecting observed system vibrations.

The sensitivity of these sensors normally ranges from 10 mV/g to 100 mV/g, and there are lower and higher sensitivities are also accessible. The sensitivity of the sensor can be selected based on the application. So it is essential to know the levels of vibration amplitude range to which the sensor will be exposed throughout measurements.

Vibration Sensor Types

The types of vibration sensors include the following.

Accelerometer Sensor

This sensor is used for general purposes like vibration and shock

Strain Gauge Sensor

These sensors are used for curved surfaces. When mass and size are significant, then strain data is required.

Velocity Sensor

These sensors are used for high-temperature applications like above 700 °F.

Gyroscope Sensor

These sensors are used where orientation information is necessary.

Pressure or Microphone Sensor

These sensors are used for health monitoring, as well as to determine vibration frequency.

Laser Displacement Sensor

This sensor is used to calculate the displacement straight without changing the product or structure.

Capacitive Displacement or Eddy Current

This sensor is used to calculate the displacement straight without changing the product or structure.

Vibration Meter

This type of sensor is used in the diagnosis of equipment.

Vibration Data Logger

Save time & cost, testing in the field (portability important)

Applications

The applications of vibration sensors include different industries for measuring the vibration. The exclusive industrial characteristics will decide sensor characteristics.

For instance, this sensor is used in industries like wind power and mining for slow rotation of turbines with 1 Hz or less frequency response.

In disparity, the industries like gas and oil need high frequency ranges from 10 Hz to 10 kHz uses these sensors to handle with the speed rotation of gears and turbines.

The industries which use the vibration sensor mainly include food & beverage, mining, metalworking, gas & oil, paper, wind power, power generation, etc.

Thus, this is all about vibration sensor. From the above information, finally, we can conclude that vibration is a difficult measurement which includes different parameters. Based on the goals of vibration measurement, the measurement technologies have benefits and drawbacks. These sensors are mainly used for measuring, analyzing, displaying, proximity, acceleration, displacement, etc. Here is a question for you, what are the advantages of vibration sensor?
