Sercel L-22D Sensor Responses

Coil and shunt resistance values affect the sensitivity, damping and pole values. To calculate poles, zeros and sensitivities for L-22Ds built with other resistor values, click here.

Note:

These responses assume that the input resistance of the attached amplifier or datalogger is at least 2 orders of magnitude larger than the shunt resistance. If this is not the case, total damping will not be 70% and the poles will not describe the system accurately.
