The invention discloses an electromagnetic balance type acceleration sensor, which comprises a packaging shell. A packaging cover is arranged at the upper end of the inner side face of the packaging shell. The packaging shell is in sliding connection with the packaging cover. A limiting ring is arranged on the upper surface of the packaging shell. The lower surface of the limiting ring is in contact with the upper surface of the packaging cover. Four first annular pieces, which are uniformly distributed, are arranged on the upper surface of the limiting ring. Four uniformly distributed cylindrical nuts are arranged at the upper end of the side face of the packaging shell corresponding to the first annular pieces. The electromagnetic balance type acceleration sensor can be used for detecting the pressure-borne time of a pressure sensor through the pressure sensor and a timer. Meanwhile, the displacement distance of the packaging cover can be detected through a photoelectric detector, sothat the acceleration is obtained. Moreover, a guide rod can also reach a new balance state through an electromagnetic inductor, so that the acceleration sensor is not easily influenced by the external environment. The electromagnetic balance type acceleration sensor is high in measurement precision, simple in operation and convenient to use.
Description
technical field [0001] The invention relates to the technical field of acceleration sensors, in particular to an electromagnetic balance type acceleration sensor. Background technique [0002] Traditional acceleration sensors are divided into piezoelectric, piezoresistive, capacitive, pendulum, etc. Piezoelectric acceleration sensors are self-generating sensors, the output charge is proportional to the input acceleration, relatively small in size and long in life, but the signal needs to be longer Large amplification, the sensor body is easily affected by temperature, and the error of the sensor itself is easy to increase, which is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an electromagnetic balance acceleration sensor, which is not easily affected by the external environment, has high measurement accuracy, is simple to operate, and is convenient to use...
