Individual calibration of multiple thermocouples can work out very expensive and increase delivery times. In order to combat this, the CCPI Europe calibration laboratory developed the coil calibration concept.
This entails manufacturing a thermocouple from each end of a coil of thermocouple wire and calibrating them over their complete temperature range and the results tabulated showing conformity to the relevant standards I.E AMS2750, RPR953, BAC5621, BS 2M54 and AIAG CQI-9. We have proved through extensive testing that the mean of these results can then be applied to ALL the thermocouples produced from this coil and all Aerospace auditors agree and accept coil calibrated thermocouples
The advantages are:
- The customer is supplied with a “virgin“ thermocouple
- The cost of the Calibration is shared between all thermocouples made from this coil
- Delivery times are reduced as there is no extra laboratory time to be added to manufacturing time
- Enables thermocouples to be manufactured and held in stock for immediate delivery as the “calibration countdown” only starts from first use
