The accelerometer shock calibration system SCS-ACS adopts the principle of piston pneumatic shock to generate physical acceleration, and is designed with reference to the ISO16063-22 standard. Under the automatic control of the software, by controlling the shock pressure and the valve switch, the half-sine acceleration peak value of 25g~2000g is obtained. Endevco 2270, as the reference standard acceleration sensor, has long term stability with high resonant frequency. The system is automatically controlled by software, the calibration report is automatically generated, and the report template can be customized according to requirements.
