CCPI Europe’s Laboratory pioneered the implementation of the coil calibration concept in the late 1990’s before the approval of Aerospace & Automotive specifications (AMS2750 & CQI-9).
We conduct this calibration option to deliver accuracy, consistency and suitability when our thermocouples are used in temperature measurement applications.
What is a coil calibration?
The calibration of coils is the method used to qualify a reel or coil of thermocouple wire / thermocouple cable as suitable for use in temperature measurement applications.
All aerospace and automotive heat treatment specifications confirm this as an approved way of identifying and qualifying a coil or reel of thermocouple wire or cable.
This method of calibration is used for;
Base Metal (Types K, N, T or J) and Noble Metal (Types R, S or B) metal thermocouple combinations.
Base Metal Thermocouples
Coil calibrations are conducted using the comparison calibration method on base metal thermocouple combinations, by sampling and calibrating both ends of a coil of base metal thermocouple wire or cable. This is conducted over a wide calibration temperature range, allowing both accuracy and consistency of the coil to be established. Thermocouples can be manufactured from the remaining coil length and data from the calibration can be attributed to the finished thermocouples. This provides a detailed wide temperature range of calibration data for the thermocouples which gives a significant saving from the conventional individual thermocouple calibration method.
