Differential charge amplifiers, standard (non-Ex) version / 5181A

These differential charge amplifiers are available in two enclosure and various voltage and current output versions. Type 5181A has a selectable charge conversion factor (sensitivity) which is factory set and contains no reset-function but a high-pass filter (time constant) at the input stage. An internal compensation circuit eliminates the drift of the amplifier and compensates low frequency error currents up to 5 nA. The 18 … 30 VDC supply voltage is galvanically separated which prevents ground loop issues. This amplifier is available in Al-die cast casing or DIN rail enclosure.
