Sensitivity

Generally speaking, the more sensitive the better. The more sensitive the sensor is more sensitive to changes in acceleration within a certain range, and the greater the change in output voltage, which makes it easier to measure and obtain more accurate measurement values. The minimum acceleration measurement value is also called the minimum resolution. Taking into account the noise problem of the post-amplification circuit, it should be as far away as possible from the minimum available value to ensure the best signal-to-noise ratio. The maximum measurement limit should consider the non-linear influence of the accelerometer itself and the maximum output voltage of the subsequent instrument. The estimation method is: the maximum measured acceleration × the charge/voltage sensitivity of the sensor.

Whether the above value exceeds the maximum input charge/voltage value of the supporting instrument, it is recommended that if the measured acceleration range is known, it can be selected in the "reference range range" in the sensor index (taking into account the frequency response and weight). At the same time, in the frequency response and weight If allowed, the sensitivity can be considered higher to increase the input signal of subsequent instruments and improve the signal-to-noise ratio.
