BISOPE series 49- Classification of sensors for dynamic load (vibration, pressure, force) measurement (DC sensor and AC sensor)

-------------------------------------------------------------------------------------------------------------

There are two types of vibration sensors according to the classification of signals according to time. There is an eddy current type (proximity probe) displacement sensor that is representative of DC sensors that can measure both the amplitude that repeats around the reference position and the length outside the reference position, and measures only the amplitude that repeats around the typical reference position of AC sensors. There is also a 'piezo electric acceleration sensor' that can do it. In addition, there are MEMS accelerometers or gyroscopic sensors that can additionally know the installation direction of the sensor based on the gravitational acceleration as well as the amplitude repeated around the reference position.

​Difference between DC and AC (oscillation)

 

Since there are various types of vibration sensors, it is not so easy to choose. However, the most important question to keep in mind is "Does it measure dynamic only or is it a vibration sensor that can measure static as well?" This is a very important point.
