The purpose of the present study is the development of commercial disposable component sensor for alloy bath. The EMF of the following zinc concentration cell has been measured by using several kinds of zinc sensors. Zn (s. or 1.) /Zn^<++>/Zn-Sn or Zn-Pb alloys (1.) Zn-Cu (s.) /Zn++/Zn-Sn or Zn-Pb alloys (1.)The reference electrode in sensor is the galvanized steel wire or liquid zinc in a capsule and the composite electrolyte consist of the molten salt (ZnCl_2+KCl+LiCl) coexisted with solid KCl powder in sensor.The following experimental results has been shown.1. The measured EMF values are in agreement with the reliable data in previous paper.2. The response time of sensor found to be 30〜60 s in the present small alloy bath. And this response time has been confirmed to be correspond to that of temperature based on this experiment. So in the case of large scale alloy bath the response time could be expected to be shorten to 2〜3 s.3. Solid reference electrode is better than liquid because sensor type can be simple and the assembling can be easy.4. The assemble of the sensor with the composite electrolyte found to be the most desirable method as follows. The composite electrolyte could be molten in a single liquid phase and sensor capsele dipped in the liquid and take up from the liquid in a moment.

本研究的目的是开发一种用于合金熔池的商业一次性成分传感器。用几种不同的锌传感器测量了锌浓差电池的电动势。Zn（s.或1.）/Zn-Sn或Zn-Pb合金（1.）Zn-Cu（s.）/Zn++/Zn-Sn或Zn-Pb合金（1.）传感器中的参比电极为镀锌钢丝或锌液，传感器中的复合电解质为熔盐（ZnCl_2+KCl+LiCl）与固体KCl粉末共存.实测电动势值与文献中的可靠数据相吻合.传感器的响应时间为30 ~ 60 s.并通过实验验证了该响应时间与温度响应时间的对应关系。因此，在大型合金熔池的情况下，响应时间有望缩短到2 μ s.固体参比电极比液体参比电极传感器结构简单，易于组装.发现用复合电解质组装传感器是最理想的方法，如下。该复合电解质可熔融成单一液相，传感器可浸入液体中，瞬间从液体中取出。
