Coil resistance values affect the sensitivity, damping and pole values. The responses given here are invalid for coil resistances other than listed. It describes a level geophone with nominal attributes. It is always recommended that these nominal responses be updated based on calibration measurements for each sensor.
The response given here assumes that the input resistance of the attached amplifier or datalogger is at least 2 orders of magnitude larger than the sensor impedance. If this is not the case, the poles will need to be updated. This find out do this, click here.
