Shock wave pressure measurement by memorized technique

Aim: Airblast overpressure measurement play an important role in engineering field especial in military field. To improve the methods of airblast overpressure measurement and to resolve in practice. Method: Based on memorized test and measurement technique, an overpressure gauge is developed. Encapsulate pressure sensor, circuit, AID conversion, trigger control circuit, communication interface and batteries in steel shell tightly. The overpressure equipment work independently and convenient to carry. Result: Develop airblast overpressure measurement that sampling frequency programmable successfully, and test shock wave in several point that 0.6kg TNT blast. The data are credible and perfectly. The curve of airblast overpressure is given. Conclusion: The memorized technique of airblast overpressure measurement has advantages of anti-interference and no-need of cable.
