Product Introduction
Made of a structure and metal material similar to the frequency response of the human head, the frequency response is flat below 1400Hz, and the Z-low resonance frequency is 2500Hz. The head type is divided into five types: A, E, J, M and O, which shall comply with Table 7 of GB 811-2022 standard. The total mass of the head includes the sensor and the connector, wherein the mass of the sensor and the connector is not greater than 25% of the total mass of the head, and the acceleration sensor is installed in the center of gravity of the head. When using a single-axis acceleration sensor, the sensor sensitive axis should be adjusted to the vertical direction of 5? Within. The shape and size of the head above the reference plane shall comply with Appendix A of the GB811-2022 standard, and the shape and size of the head below the reference plane shall comply with Appendix B of the GB811-2022 standard. With the head type of the single-axis acceleration sensor, the size of the part below the reference plane should be greater than or equal to 44.5mm.
