The pin shape probe and corresponding experiment method was designed to measure the precision steady detonation velocity. The steady detonation velocities of sheet insensitive high explosive (IHE) based on TATB at the restricted by polymethylmethacrylate, stainless steel and aluminum alloy were measured by needle shape pins, and the uncertainty of measurement velocity was analyzed. The result shows that the uncertainty of detonation velocity in IHE based TATB measurement using this method is not exceed 19 m·s^-1, and the relatively uncertainty is not exceed 0.25%. Results are accordant with the precision detonation physics experiment result of Los Alamos National Laboratory (LANL). It is a high precision detonation velocity measurement method for precision detonation physics.
