The CH-1200A is a high-performance charge amplifier to convert charge signal to voltage signal. Built-in integration function allows optimization of the signal which is input to the vibration data analyzer connected.
Changing into a multi-channel amplifier is easy by connecting multiple units.
- Built-in integration function – Output data can be selected from acceleration, velocity and displacement.
- Filter function – High-pass filter and Low-pass filter remove unwanted vibration and enable more precise measurement.
- Compact, light weight and easily changed to a multi-channel amplifier by connecting units.
