Coil and shunt resistance values affect the sensitivity, damping and pole values. To calculate poles, zeros and sensitivities for sensors built with other resistor values, click here.
These responses assume that the input resistance of the attached amplifier or datalogger is at least 2 orders of magnitude larger than the parallel sum of the coil and shunt resistances. If this is not the case, total damping will not be 70% and the poles will not describe the system accurately.
