Sercel L-10 Sensor Responses

Coil and shunt resistance values affect the sensitivity, damping and pole values. The amplifier/datalogger impedance can affect these as well. To calculate poles, zeros and sensitivities for L-10s built with other resistor values click here. In addition, the L-10AR sensors have a fundamental frequency that can range between 10 and 14 Hz. The fundamental frequency value affects the current damping, which in turn affects the poles. This link also shows how to calculate the poles for other fundamental frequencies.

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 change and the poles will not describe the system accurately. See the above link to take datalogger input impedance into account.
