Motion Sensors - Accelerometers

Accelerometers are motion sensors that measure linear acceleration (the rate of change of velocity with respect to time). In this article, we will discuss the application field and working principle of the ADXL346ACCZ-R2 accelerometer.

Application Fields

ADXL346ACCZ-R2 accelerometers are most commonly used for vibration monitoring, inclinometry, and shock detection. Vibration monitoring is a large and ever growing application for accelerometers, as vibration monitoring can be used to identify stability and safety issues with machinery performance and load bearing structures. ADXL346ACCZ-R2 accelerometers are also used in many automotive, robotics, and aerospace applications.

In industrial settings, these accelerometers are used for the detection and measurement of vibrations in machinery and equipment, ensuring a safe and reliable operation. They are also used in medical environments for measuring physical dynamics such as G-force and balance. Moreover, ADXL346ACCZ-R2 accelerometers can be used in aerospace for analyzing forces and acceleration due to lift, drag, and air turbine engine operation.

Working Principle

The ADXL346ACCZ-R2 accelerometer is a three-axis accelerometer, meaning it has one sensing element for each of the three axes (x,y,z). This device measures linear acceleration using the piezoelectric effect in order to measure static or dynamic acceleration caused by gravity or movement. For each axis, the sensor can detect acceleration up to ±4g.

The piezoelectric effect relies on the fact that when mechanical stress or strain is applied to a Piezoelectric material, an electric voltage is generated on the material\'s surface. Inside the ADXL346ACCZ-R2 accelerometer, the Piezoelectric effect is generated using two crossed piezoelectric plates and an oscillator. As the sensor is subjected to acceleration, the plates react to the change in acceleration by generating a voltage proportional to the acceleration. This voltage is then amplified and sent to an analog to digital (ADC) converter for processing.

The ADXL346ACCZ-R2 accelerometer utilizes a temperature compensation technique in order to provide more accurate and reliable data even when the temperature of the environment changes. This temperature compensation system uses a reference circuit to reduce the effects of temperature variations on the output signals from the sensor.

Conclusion

ADXL346ACCZ-R2 accelerometers are the perfect choice for applications requiring the detection and measurement of vibrations in machinery and equipment. The accelerometer relies on the piezoelectric effect and a temperature compensation technique in order to provide accurate data even when the temperature of the environment changes.
