    • PROBLEM TO BE SOLVED: To provide a sensor probe capable of minimizing influence of reference gas or the like on a measuring target.SOLUTION: In a sensor probe 1 including a cylindrical sleeve 4 having an aperture 4a on a tip part, a rod-like sensor (solid electrolyte 2) located in the sleeve 4 and an interposed material 5 elastically interposed between an outer peripheral surface of the sensor and an inner peripheral surface of the sleeve 4 to hold the sensor in the sleeve 4, the interposed material includes a melting material allowed to be melted in a use environment to airtightly block an inner space of the sleeve in an axial direction. In the configuration, since the inner space of the sleeve is airtightly blocked in the axial direction in the use environment, reference gas or the like is prevented from arriving at a measuring target through the sleeve and accurate measurement can be achieved.
    • 要解决的问题:提供能够使参考气体等对测量对象的影响最小化的传感器探针。解决方案:在包括在尖端部分上具有孔4a的圆柱形套筒4的传感器探针1中,棒状 传感器(固体电解质2)和弹性插入在传感器的外周面和套筒4的内周面之间的夹持材料5,以将传感器保持在套筒4中,夹持材料包括熔融 允许在使用环境中熔化的材料以沿轴向气密地阻塞套筒的内部空间。 在该结构中,由于在使用环境中套筒的内部空间在轴向气密地阻塞,因此可以防止参考气体等通过套筒到达测量对象物,并且可以实现精确的测量。

    • PROBLEM TO BE SOLVED: To provide a sensor probe which is for a sensor for making measurements in molten metal and is capable of protecting the sensor from being damaged by thermal shock without requiring preheating that takes a long time.SOLUTION: A sensor probe 1 comprises a rod-like sensor 2 whose tip portion is immersed in molten metal, and a thermal shock moderator 4 which is attached to the tip portion of the sensor 2, is made of a same metal as the molten metal, and is designed to melt in the molten metal and disappear. Because the thermal shock moderator 4 melts and disappears in the molten metal when the tip of the sensor probe 1 in this configuration is immersed in the molten metal, the heat capacity reduces the rate of temperature rise of the sensor, which prevents the sensor 2 from being damaged by thermal shock. Also, since the thermal shock moderator 4 is gone after measurement is completed, the sensor 2 is not subjected to an unnecessary load when being cooled down to room temperature, which prevents damage while being cooled down.
    • 要解决的问题:提供一种用于传感器的传感器探头,用于在熔融金属中进行测量,并且能够保护传感器免受热冲击的损害,而不需要长时间的预热。解决方案:传感器探头1包括 将其前端部分浸入熔融金属中的杆状传感器2和安装在传感器2的顶端部分上的热冲击减速器4由与熔融金属相同的金属制成,并被设计成熔化 熔融金属消失。 因为当这种结构中的传感器探针1的尖端浸入熔融金属中时,热冲击调节剂4在熔融金属中熔化并消失,所以热容量降低了传感器的温度上升率,从而防止传感器2 被热冲击损坏。 此外,由于在测量完成之后热冲击调节器4不见了,当被冷却到室温时,传感器2不会受到不必要的负载,这防止在被冷却时的损坏。
