Productdatasheet_german charge amplifier (hol350)

Description: 

The charge amplifier hol350 enables the connection of vibration acceleration sensors, which have no integrated electronic charge amplifiers. Using ICP® output subsequent evaluation circuits are connected.

The device offers with the high-pass and the antialising-filter the possibility for a direct connection to an AD-card. The sensor input and the ICP® output are galvanically seperated.Through the robust plastic terminal cabinet for the snap rail systems and the easy installation and handling of the amplifier, a high reliability is guranteed.

Application fields: 

At all technical applications in which vibrations occur, the charge amplifier(hol350) is a valuable support. Here some examples:

 

  • Amplification (processing) of small signals
  • Adaptation of sensors to evaluation circuits with ICP® input       
  • measurement equipment (e.g. oscilloscope) computer interfaces or -cards
