Sercel SGHT-15 Sensor Responses

Coil and shunt resistance values affect the sensitivity and pole values. To calculate poles, zeros and sensitivities for SGHT-15s built with other resistor values, or to take datalogger impedance into account, 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 dampling will not be 100% assumed below and the poles will not describe the system accurately.
