| According to the structure of the platinum channel as well as the requirement on the temperature and temperature control precision for each section, this paper gives a brief introduction of an electric heating system for the platinum channel. The designed electric heating transformers have three specifications of A1 and A2 categories, with output power in the range of 60%-90%. Non-contact thermocouples are used and their temperature measurement precision reaches ±0.03%. The design scheme makes it possible to realize accurate control over the electrical parameters of the platinum load in the case of high loop current. The output voltage can be regulated at random in an accurate way, so that the problem of inadequate utilization of electrical energy is solved, the service life of the thermocouple is elongated, and the rate of good product is raised. |
