| Summary: | In electroheat processes used in the metallurgical industries it is often desired to hold metallic charges at a temperature corresponding to their solid/liquid stat? interface. Similar requirements exist in the manufacture of chocolate, wax and similar products. A solid/liquid state sensing transducer has been developed in which a probe is plunged into and withdrawn from the charge. The armature current of the servomotor driving the probe gives information as to the state of the charge. A form of this transducer was developed which gave excellent results in holding metallic charges. The final transducer was well within the accuracy requirements of industrial processes, yet was unsophisticated and could easily be inexpensively constructed. |
