Platinum rhodium thermocouple is widely used in powder metallurgy industry

Industrial use of platinum rhodium thermocouple we can also call it precious metal thermocouple, small make up have to introduce you before about the working principle of platinum-rhodium thermocouple, the main technology and platinum-rhodium thermocouple are widely used in our daily life.

platinum-rhodium thermocouple is also called the precious metal thermocouple, because it is primarily as a measurement of the temperature of sensor, so under normal circumstances is needed and temperature transmitter, controller and display instrument of all, combine together to form a process control system, are mainly used for direct measurement or control 0 - different production process Fluid over a range of 1800 ℃, gas, or steam, some fixed surface temperature is also included. Platinum-rhodium thermocouple in the heat of electric heat will mainly by measuring the temperature increase, and the size will be according to the thermocouple at the ends of the material and temperature are mainly linked, but doesn't have anything to do with hot electrode diameter and length. The appearance of platinum rhodium thermocouple will mainly because of the demand is different, but there is no too big change on the basic structure, mainly by protecting tube, thermal insulation sleeve of electrodes and wiring of the box. Platinum-rhodium thermocouple are mainly two kinds of different ingredients of conductor on both ends together to form a loop, so if on both ends of the junction temperature is different, so there was a thermal current will be in the loop. But if the thermocouple reference end and work end in temperature difference, then shows the instrument will direct instructions from the corresponding temperature of thermoelectric potential. Platinum rhodium thermocouple is suitable for application in the production of various kinds of high temperature in the process, is widely used in high temperature such as smelting furnace, powder metallurgy and glass industry.
