SHOWA SOKKI 4001B-50 Charge amplifier for force sensor and pressure sensor

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 4001B-50

Features

This is a charge amplifier for piezo-type force sensors and pressure sensors.
Unlike general charge amplifiers, this charge amplifier can measure almost from DC.
The discharge time constant can be switched between LONG and SHORT, and low frequency response characteristics can be selected.
The charge amplifier Model-4001B-50 is suitable for the following applications: ・”Force” measurement with a wide dynamic range
・Measurement of impact “force”
・Measurement of engine combustion pressure
・Measurement of compressor pressure, etc.
