charge amplifier (hol350)
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.
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
