A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor. Range most popular calibration. Type t thermocouple copper constantan. Type j thermocouple iron constantan composed of a positive leg which is iron and a negative leg which is approximately 45 nickel 55 copper.

328 to 662 f 250 to 350 c extension grade. The type t is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers. It is found in other laboratory environments as well. The calibration table for a copper constantan thermocouple which is employed for temperature measurement gives the temperature t in o c for different values of the voltage output v in millivolts mv.

Typical response time for thermocouples. Range of temperatures from 270 with to 400 with. Since the ranges for calibrations tend to overlap there are other considerations in the selection criteria. Using interpolation with a cubic spline for the following data compute the temperatures corresponding to thermocouple outputs of 0 9 and 1 75 mv.
