Study on influence factors of underwater shockwave sensor dynamic calibration

To test coefficient sensitivity of underwater shockwave pressure sensor, dynamic calibration is conducted using traceable standard bench sensor and PCB913B02 sensor calibration equipment. In the research, silicon oil of different specification was filled into sealed tank in order to study the relations between silicon oil specification and calibration result of pressure sensor. Explosion tests are conducted using explosives of different formulas and underwater shockwave sensors filled with silicon oils of different specifications. The test result shows such principle and the method of calibration mentioned above could ensure the calibration precision, which therefore certifies the accuracy of shockwave pressure test.
