Sercel L-22E Sensor Responses

Coil and shunt resistance values affect the sensitivity and pole values. To calculate poles, zeros and sensitivities for L-22Es built with other resistor values, or to take datalogger impedance into account, 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 shunt resistance. If this is not the case, total dampling will not be 100% assumed below and the poles will not describe the system accurately.
