Working of an Accelerometer Explained

Accelerometer users typically sense changes in velocity and characterize outputs and errors in g. Jewell accelerometers are precision inertial sensors. They utilize closed-loop sensor technology to produce a accurate output with high resolution. The inertial sensor output is an analog voltage, current, or digital signal proportional to applied acceleration and tilt from DC through a specified frequency. Jewell has produced inertial sensor torquers and complete acceleration sensing assemblies for many years. Jewell inertial sensors are used throughout the world for detecting acceleration from less than one µG to more than 40G. An inertial sensor responds to both earth’s gravity and acceleration.

Tips to Choose the Best Accelerometer Sensor for Your Application

Choosing the right accelerometer sensor for your application can be a challenging task. The following pointers will be helpful.

  • Type of Measurement: Accelerometers can be used to measure the following parameters:
    • Vibration: This happens when an object oscillates about its position. Vibration is a common occurrence in automotive and machining environments.
    • Motion: This is the moving characteristic of any industrial machinery.
    • Shock: A body resonates when there is a sudden excitation of the structure.
    • Seismic: It is a low-frequency vibration, requiring high precision accelerometers.
  • Measuring Range: These accelerometer sensors utilize a sensor in the acceleration up to 40G.
  • Environment: The operational environment of the accelerometer needs to be considered. This consideration may involve several parameters, including maximum acceleration levels, humidity, temperature, and so on.
  • Technical Support: A knowledgeable sales team at the manufacturer’s end will help you choose the right accelerometer sensor based on your needs.
