is one of the items that can be supplied by Salim Sanat Sepahan Company. Types of ceramic thermocouple sheaths and also the sampler can be supplied in excellent quality. Platinum / Platinum Radium thermocouple was first introduced in 1885. In this thermocouple, the positive wire contains 90% platinum and 10% radium, and the negative wire contains pure platinum.
Later, other calibrations were introduced and standardized by others, and finally three The main type for thermocouples, including platinum and its alloy, was introduced: R, S and B.
These thermocouples are commonly used to measure temperature in the steel and metal casting industries. The choice between them depends on the desired temperature for measurement, equipment calibration, and the type of compensation wires available.
The type of disposable thermocouples is B, R or S and is suitable for temperatures around 1600 1800 degrees Celsius, ie can be used in the iron and steel industry and in environments such as arc furnaces, induction and blasting. Due to their high cost and low sensitivity, these types are used only at high temperatures, and in all three, platinum or platinum-radium alloy with a variable percentage is used in each of the two poles of the thermocouple. The subcalibration table of these three types plus the upper limit of measurable temperature shows
