ACC 1831

Triaxial Accelerometer
ACC 1831 is generally used in multi-axial vibration test analysis, vehicle, aviation and other research and development and applications.
ICP (or IEPE) piezoelectric acceleration sensor uses 1/4-28UNF four-core cable to supply 2-10mA constant source power to the sensor, which is commonly called ICP mode internationally.
ACC 1831 is often used with built-in IEPE acquisition cards such as MegaSig PM 6143 to achieve excellent test results.
