Accelerometers are motion sensors used to detect and monitor acceleration, velocity and orientation changes in three dimensional space. The PMMA2240KEG is an accelerometer designed for vibration and shock protection in consumer electronics. This accelerometer has a wide range of applications due to its low power consumption and high efficiency.The PMMA2240KEG accelerometer is made up of a piezo-electric ceramic mass attached to the bottom of a spring. With the addition of a mounting bracket, this accelerometer can also be attached to the exterior surface of an object. The accelerometer is able to detect changes in the electrical resistance of the piezo-electric mass due to the deformation of the spring, which is caused by an acceleration force.The principle of operation is based on the change in electrical resistance in the piezo-electric mass when the applied accelerative force changes. When an acceleration is experienced, such as when a surface is perpendicular to the gravity force, the piezo-electric mass is displaced in the opposite direction. The displacement causes a change in electrical resistance and this measured change in resistance can be used to calculate the acceleration experienced.The PMMA2240KEG accelerometer can be used to measure both static and dynamic acceleration. It is widely used in consumer electronics for a range of applications such as vibration and shock protection. It is also used in automotive applications such as suspensions system control and crash detection. In addition, it can be used for navigation and tilt sensing.In order to ensure accurate readings, the accelerometer must be properly calibrated. This is done using a reference signal which is generated by a known acceleration force. The reference signal is then compared to the readings from the accelerometer to ensure that they are the same.In summary, the PMMA2240KEG accelerometer is used to detect and monitor acceleration, velocity and orientation changes in three dimensional space. It is made up of a piezo-electric ceramic mass attached to the bottom of a spring and is primarily used for vibration and shock protection in consumer electronics. The principle of operation is based on the change in electrical resistance in the piezo-electric mass when an acceleration force is experienced. The accelerometer must be calibrated before it can be used for accurate readings.
