The invention disclosed in the invention belongs to the technical field of instruments, in particular to a high-precision shock-resistant pressure gauge with temperature compensation, comprising a joint, a dial, a dial, a shell, a back plate, a main cover and a sub-cover, and the top of the joint is Weld the dial, the left side wall of the dial is glued to the dial, this kind of high-precision shock-resistant pressure gauge with temperature compensation, when encountering high temperature, the temperature sensor on the back plate can measure the internal temperature of the casing. Detection, when the temperature exceeds the preset threshold, the stepper motor is controlled to rotate the shaft once, so that the auxiliary cover sleeved with the shaft rotates in the main cover ring groove of the main cover to form a gap, which is convenient for air circulation and accelerates the arc plate. The air exchange speed and the cooling speed are improved. After the dial groove is opened on the dial, the arc cover glass is added to shield the pointer. The shape of the arc cover glass can effectively disperse and relieve the pressure, and cooperate with the outer glass plate to form a double-layer glass. The effect increases the shock resistance and ensures the safety of the main components.
