Abstract: Describes methods for the analysis and processing of analog signals representing particle velocity for pressed TNT. Methods of calcularting the dynamic conductance and zero-load currents of the particle-velocity gauge and detonation-products gauge are likely described. The correction function for eliminating the influence of conductivity of detonation products is also given. The detonation parameters of TNT explosive obtained by the corrected particle velocity records (analog signals) agree well with those measured by other methods.
