Multi-functional acceleration detector charge amplifier
CH-1200A

The CH-1200A is a high-performance charge amplifier designed to convert charge signals into voltage signals. By incorporating an integration function within the unit, it is possible to optimize the input signals for connected vibration data analysis equipment. Furthermore, multiple CH-1200A units can be linked together to be used as a multi-channel charge amplifier.

Features

  • Integrated integration function – capable of selective output of acceleration, velocity, and displacement data.

  • Equipped with filter functions – High-pass and low-pass filters eliminate unwanted vibrations, enabling more precise measurements.

  • Compact and lightweight, also supports multi-channel configuration through body connection.
