HA602-A100 Series

Sensitivity is a ratio between output Voltage Vout and input acceleration. S is measured at one frequency (100Hz for CTC) and is in units of mV/g (for acceleration). The upper limit at which we specify +/-10% is based off of the sensitivity value at 100Hz.

Dynamic Range is the maximum positive/negative peak amplitudes of acceleration that can be measured without clipping or distorting the corresponding vibration signal. Important note, the maximum value is limited by the open circuit (OC) IEPE voltage (supply compliance voltage), and the negative value is limited by the bias voltage of the sensor. Exact maximum and minimum dynamic range values for a given sensor can be approximated as follows: gMAX = (VSource – Vbias)/Vsensitivity gMIN = -(Vbias - 3V)/Vsensitivity

Amount of time taken for the sensor to reach 95% of its steady state bias voltage when turned on.

Bias Output Voltage is steady state DC offset voltage on which the vibration signal is superimposed.
