5185A

Ex-ec version of the differential charge amplifiers family Type 518x which offers highest flexibility, wide selectable gain, low and high pass filters and many signal output options. This amplifier is available in Al-die cast casing or DIN rail enclosure.
Main features / advantages
  • Selectable high and low pass filters
  • Very large charge conversion range
  • Various executions and output options
  • Suitable for ground isolated measuring chains
These differential charge amplifiers are available in two enclosure and various voltage and current output versions. Type 5185A 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.
