Question

the temperature measurement by a Thermocouple is​

Answer 1

Answer:

metal-specific resulting in a variety of measuring ranges of -200°C to +2500°C.

Explanation:

• A thermocouple refers to a device or sensor that is often used in every industry, including aerospace, factory automation and process control to medical sciences to measure a high temperature of a range -200°C to +2500°C.

• Thermocouples comprise two wire legs made up of dissimilar metals, joined together to form a junction point.

• The heating or cooling of this junction creates a small voltage in the electrical circuit of the thermocouple that can be measured and this relates to the temperature measurement of a varied range.

• The pairing of different kinds of metals gives thermocouple types, for example, type J, type B, type T, type E, Type S, type R etc.

• Type J, type T, and type E are base metal thermocouples and type R, type S & type B are noble metal thermocouples.

Hence the temperature measurement by a Thermocouple is​ metal-specific resulting in a variety of measuring ranges of -200°C to +2500°C.
