This article compares different measurement principles for acceleration measurement
Each measurement principle has its advantages and disadvantages. The following table gives an overview of the combination between measurement principles and measurement problems.
Piezo-electrical and inductive sensors are not able to measure static accelerations. Any other combination is possible. The optical sensor can be used for every measurement task. The limiting factor for the measurement performance of an optical based sensor is the mechanical transducer.
Further problems for selecting an appropriate sensor for a specific measurement application are the requirements in terms of measurement range, dynamic range and sensitivity.
The measurement range, dynamic range and sensitivity are independent. If an enhancement for one of these properties is required, it is only able to fulfil this requirement with a degradation of the other properties.
For example, the higher the measurement range is required, the less the sensitivity of the sensor can be for a certain dynamic range. Sensors which use a cantilever as the transducer must make a compromise between the dynamic range and the reachable sensitivity.
All properties which concern the measurement performance are dependent on the mechanical design. The determining factor is the transducer which couples the physical acceleration to the sensing element. the design of the transducer is also responsible for properties like cross sensitivity, sensor drift or linearity.
