Abstract
A device for acquiring signals from a sensor, the device comprising a differential amplifier, two bias resistors for biasing of the measurement device, a common mode and differential mode filter circuit, and two lightning limiter components. The differential amplifier is of the high common mode range type, the limiter components are dimensioned to reduce a lightning voltage to a maximum voltage value of the order of about one hundred volts and the filter circuit and the bias resistors are dimensioned to withstand that maximum voltage value. A correspond method for protecting a device against lightning.
