Base Metal Thermocouples
Calibration of coils 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.
Noble Metal Thermocouples
Coil calibrations can be conducted using either the fixed point or comparison calibration method on noble metal thermocouple combinations. The advantages as indicated for base metal thermocouples apply when using the comparison calibration method with the opportunity of the highest level of accuracy, when the fixed-point calibration method is used.
Calibration of the coil and the combination of high-quality materials and manufacturing methods have been pioneered by CCPI Europe to enable customers to have the most cost effective, long life temperature sensors without compromising accuracy.
