Principle

The principle of servo velocity seismometers is similar to general servo accelerometers, but it
adapts the differentiating circuit in the feedback circuit.

The sensitivity of velocity seismometer is determined by the stable elements of the M, R, r, C and G. Therefore, the change in α and the scale factor of amplifier (A) do not affect the characteristics of the velocity seismometer.
This is a good point of servo velocity seismometer, and it is possible to maintain the stable sensitivity and characteristics for a long period.

The specification may change without notification because of the proved product.
