Charge Converter

CH-6130/CH-6140

The Charge Converter CH-6130/CH-6140 is a simple charge amplifier for converting charge signals into voltage signals.

In the case of charge output type acceleration sensors, a separate charge amplifier is usually required, but by using this charge converter, it can be directly connected to the BNC input terminals of FFT analyzers and the like.
Additionally, the wiring around signals and power, which can become complicated, is neatly organized.

Small and lightweight simple charge amplifier
Can be directly connected to the sensor input BNC connector of devices compatible with constant current drive (CCLD) such as FFT analyzers.
Two types are lined up: CH-6130 with a conversion coefficient of 1 mV/pC and the high-sensitivity type CH-6140 with 10 mV/pC, selectable based on the sensor sensitivity of the input acceleration sensor.
