[0002] A high temperature encoder is a position sensor that can work in extremely high temperature environments. It is used to accurately measure the position and speed of rotating or linear moving objects. It is usually used in high temperature equipment in industries such as metallurgy and glass manufacturing to ensure reliable data transmission and control signals under harsh conditions.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that it only relies on the thermal insulation layer to isolate the heat, but the thermal insulation can only isolate part of the heat, so some of the heat will continue to remain in the equipment. Under long-term operation, the continuous accumulation of heat will also have the risk of high temperature or even over-temperature, damaging the equipment, circuits, and even the scale lines, making the measurement inaccurate, and unable to timely determine whether the equipment is still in a normal working environment. At the same time, the encoder cannot fit tightly with the equipment, affecting the measurement accuracy. Inaccurate measurement leads to the inability to timely discover safety hazards, affecting the safe and stable operation of the equipment. Utility Model Content
