There are many types of accelerometers:
According to the displacement method of the detection mass, there are linear accelerometers (the detection mass is linear displacement) and pendulum accelerometers (the detection mass rotates around the support axis);
According to the support method, there are gem support, flexible support, air float, liquid float, magnetic levitation and electrostatic levitation.
According to the composition of the measurement system, there are open-loop and closed-loop types.
There are vibrating wire type, vibrating beam type and pendulum integrating gyro accelerometer according to the working principle.
Classified by the number of input axes, there are single-axis, dual-axis and tri-axis accelerometers;
Classified by sensing element, there are piezoelectric type, piezoresistive type and potentiometer type.
The characteristics of several different classifications are usually used to name an accelerometer.
