Simple sensitivity calibration for acceleration detectors
VX-1100A
Piezoelectric Accelerometer is widely used for vibration measurement. To obtain accurate measurement data, it is necessary to check the sensor's operation (sensitivity) before use.
The VX-1100A is a sensitivity calibration device for piezoelectric Accelerometer. It includes a vibration generator, sensor amplifier, and display, and by directly inputting sensor output into the device, you can read the sensitivity directly.
Additionally, the VX-1100A excites the pickup with a 159.2 Hz and 10 m/s 2 (rms) sine wave, allowing the output to be used as a calibration signal for vibration measurement systems.
