Abstract:

In order to meet the requirements of a program for measuring blast pressures of large caliber bombs at the Aberdeen Proving Ground a piezoelectric tourmaline crystal blast gage has been developed and methods of producing it in large quantities have been worked out. Successive calibrations taken on individual gages show a standard deviation from the mean rarely exceeding 1 and an output that shows no significant departure from linearity in the pressure range from three to sixteen pounds per square inch. Details of construction and calibration are given.
