FIELD: instrument making.
SUBSTANCE: method of graduation of pressure sensors for sensing of air shock wave includes the impact on the sensor of the graduating air shock wave (ASW) formed by blasting of explosive charge, measurement of amplitudes of output signal of the sensor, determination of excessive pressure in the front of graduating ASW and calculation of the sensor conversion coefficient, while directly behind the graduated pressure sensor at the distance, comparable with longitudinal size of its sensitive element, the flat rigid barrier is installed, and excessive pressure oriented normally towards the centre of explosion in the front of the falling calibration ASW is determined through the relation of amplitudes U2 and U1 of the signal registered by the sensor reflected from the barrier and falling waves from the ratio: 
, where p0 - atmospheric pressure.
EFFECT: improvement of accuracy of graduation of ASW pressure sensors.
