FIELD: rocket engineering, measurement of dynamic characteristics of powder charges. SUBSTANCE: device has case, supporting bushings for bearings, adjustment bushing with strain gauge transducer and gas piston. Vibration damping piston is installed in hole of adjustment bushing. Gas-tight cavity formed between end of piston and membrane of strain gauge transducer is filled with lubricant. Bore into which bearing with gas protection bushing is pressed is made in end of vibration damping piston. Groove is made in adjustment bushing on side of hole. EFFECT: increased accuracy of registration of parameters of powder charge thanks to damping of high- frequency vibrations and to prevention of mechanical damage to strain gauge transducer in process of formation of powder charge. 1 cl, 1 dwg
