Charge converter

CH-6130/CH-6140

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

While charge output type Accelerometer typically require a separate charge amplifier, this charge converter allows for direct connection to the BNC input terminal of an FFT analyzer or similar device. Furthermore, it simplifies the often complex wiring of signals and power supplies.

Small, lightweight, and simple charge amplifier
It can be directly connected to the sensor input BNC connector of constant current drive (CCLD) compatible equipment such as FFT analyzers.
Two models are available: the CH-6130 with a conversion coefficient of 1 mV/pC and the high-sensitivity CH-6140 with a conversion coefficient of 10 mV/pC. The choice depends on the sensor sensitivity of the input Accelerometer.
