Sources of Error in Thermocouple Measurement

A thermocouple is a widely used temperature sensor to measure temperature in any particular environment. Although the thermocouples are heavily used, there can be significant errors associated with the temperature measurements when used in different environments. If these errors are recognized and sensors are designed and used accordingly, the temperature measurement can be predicted with much greater accuracy. 

When a temperature is measured in an aircraft engine, the displayed temperature in the cockpit may not be the exact temperature what the engine actually experiences. It may contain several error sources. This paper briefly explains the physics behind thermocouples and some of the errors associated with their use. Download this whitepaper to continue reading.
