How Do I Know If My Angle Sensor Is Accurate?

It is essential to ensure that the angle sensor for your application is accurate to obtain reliable results. To ensure this, it is worth considering calibration, testing, and environmental factors.

Also, consider if accuracy is really that important. For most e-bike applications where the angle sensor is used to measure crank angle, resolution is more important than both absolute accuracy and precision.

Calibration

The first step to ensure the accuracy of your angle sensor is calibration. Calibration is the process of adjusting the sensor to match the actual angle. For Sensitivus combined torque/angle sensors, this typically happens during the design integration process.

Testing an Accurate Angle Sensor

After calibration, you can test your angle sensor to check its accuracy. You can use a reference angle sensor to compare the sensor’s reading. If the sensor’s reading matches the reference angle, it is accurate. However, if there is a significant difference between the sensor’s reading and the reference angle, the sensor may be inaccurate.

Environmental Factors

Environmental factors can affect the accuracy of your angle sensor. For example, temperature changes can cause the sensor’s readings to drift. It is essential to consider the environmental factors when testing your angle sensor’s accuracy. You can test your sensor in different environmental conditions to ensure its accuracy.
