Impact sensor, has adjusting unit adjusting pressure between tubular body and surrounding area, where tubular body is pressurized-connected with housing unit of sensing unit, and pressure is adjusted at housing unit

摘要

The sensor has a sensing unit recording pressure change in a tubular body and detecting an impact on the pressure change. The sensor is arranged in a housing unit, and an adjusting unit adjusts pressure between the tubular body and a surrounding area. The tubular body is pressurized-connected with the housing unit of the sensing unit, and the pressure is adjusted at the housing unit. A pressure compensation opening is provided at an inner side of the housing unit between the tubular body and the sensing unit, and is arranged at the housing unit of the sensing unit.
