Used to test the product's gravitational acceleration displacement, can measure the linear acceleration and rotation Angle rate from three directions, through the solution can obtain the carrier's attitude, speed and displacement information, the accuracy can reach 0.05°, can quickly and flexibly detect the equipment's acceleration displacement, in order to start the automatic protection function, improve the durability of the equipment. Avoid damage caused by falling, impact, etc. At the same time, the circuit gas circuit modular quick plug design can be compatible with more product type change requirements, and reserve the option of full automatic upgrade.
