Copper Constantan Thermocouple Calibration Table

Note constantan is copper nickel when protected by compacted mineral insulation and appropriate outer sheath type j is useable from 0 to 816 c 32 to 1500 f.

Copper constantan thermocouple calibration table.

Typical response time for thermocouples. Greater of 0 5 c or 0 4. The table below should help. You can get astm e230 e230m 17 from the ansi webstore and in it you can find a range of information on thermocouple tolerances color coding temperature limits and similar.

Mild oxidizing reducing vacuum or inert. Commercial thermocouples are inexpensive interchangeable. Thermocouple extension cables with molded connectors u retractable cable in 1 and 4 lengths. 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.

328 to 662 f 250 to 350 c extension grade. Type t copper versus copper 45 nickel constantan type c tungsten 5 rhenium versus tungsten26 rhenium other thermocouple standards. Copper constantan chromega constantan. Greater of 1 0 c or 0 75.

Type j thermocouple iron constantan composed of a positive leg which is iron and a negative leg which is approximately 45 nickel 55 copper. Range of temperatures from 270 with to 400 with. 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. The type t is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers.

Since the ranges for calibrations tend to overlap there are other considerations in the selection criteria. Range most popular calibration. Using interpolation with a cubic spline for the following data compute the temperatures corresponding to thermocouple outputs of 0 9 and 1 75 mv. 76 to 212 f 60 to 100 c 454 to 752 f 270 to 400 c 6 258 to 20 872.
