Copper Constantan Thermocouple Calibration Table

The table below should help.

Copper constantan thermocouple calibration table.

Greater of 1 0 c or 0 75. Range most popular calibration. Type j thermocouple iron constantan composed of a positive leg which is iron and a negative leg which is approximately 45 nickel 55 copper. 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.

It is found in other laboratory environments as well. 328 to 662 f 250 to 350 c extension grade. 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. Since the ranges for calibrations tend to overlap there are other considerations in the selection criteria.

Commercial thermocouples are inexpensive interchangeable. 76 to 212 f 60 to 100 c 454 to 752 f 270 to 400 c 6 258 to 20 872. Calibration length recj1 30 cm 1 recj4 120 cm 4 reck1 30 cm 1. Copper constantan chromega constantan.

Range of temperatures from 270 with to 400 with. Typical response time for thermocouples. Using interpolation with a cubic spline for the following data compute the temperatures corresponding to thermocouple outputs of 0 9 and 1 75 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.

Type t thermocouple copper constantan. Mild oxidizing reducing vacuum or inert. Calibrating calibration charts of thermocouple. Type t copper versus copper 45 nickel constantan type c tungsten 5 rhenium versus tungsten26 rhenium other thermocouple standards.

Greater of 0 5 c or 0 4. Thermocouple extension cables with molded connectors u retractable cable in 1 and 4 lengths.
