ACCELERATION SELF-COMPENSATING PRESSURE TRANSDUCER

The utility model provides a pressure transducer which plays the role of self-compensation in movement acceleration, comprising a transducer main body, a special foil strain gauge, an insulating base, and a needle base. The middle part of the transducer main body is provided with a lug boss to ensure that movement direction of the center axis of the transducer is consistent with the movement direction of a movement piece. The transducer is fixed on the movement piece to measure gas pressure surrounding the movement piece so that system error caused by movement acceleration is automatically eliminated. The utility model is particularly suitable for the measurement of base pressure curve in gun and cannon shooting, the measurement of the pressure curve of combustion chambers in rocket flights, and accurate measurement of the push pressure of working medium gas on an actuating piece in the overall working process of an air hammer, a pneumatic tool, and other products.
