High-temperature liquid metal probe

The invention belongs to the technical field of liquid metal detection instruments, and particularly relates to a multipurpose probe applied to high-temperature liquid metal liquid level detection andtemperature measurement. The probe comprises a structural member, a transition connecting member, an insulating member and a sealing member. Wherein the insulating part is made of a high-temperature-resistant ceramic material. Structural member made of stainless steel material. The structural member comprises a threaded male joint, an upper pressing member, a threaded female joint, a lower connecting pipe and a central probe. The insulator includes: a ceramic tube; the high-temperature liquid metal probe adopts a ceramic tube which is a structural part and an insulating part, and the sealingpart adopts a metal gasket; when other structural parts and connecting parts are made of stainless steel materials, the highest use temperature can reach 650 DEG C. If a nickel-based alloy or a refractory metal material is used for replacing the probe and the threaded connecting piece, the temperature resistance can be further improved to 1000 DEG C. 本公开属于液态金属的检测仪表技术领域，特别涉及一种应用于高温液态金属液位探测及温度测量的多用途探针。该探针包括：结构件、过渡连接件、绝缘件、密封件；其中绝缘件采用耐高温陶瓷材料。结构件采用不锈钢材料。结构件包括：螺纹公接头、上压紧件、螺纹母接头、下接管、中心探针；绝缘件包括：陶瓷管；高温液态金属探针采用陶瓷管，其既是结构件又是绝缘件，而密封件采用的是金属垫片；在其他结构件、连接件使用不锈钢材料件时最高使用温度可达到650℃。若使用镍基合金或难熔金属材料替代制作探针和螺纹连接件，还可将耐温能力进一步提高到1000℃。
