The primary distinction between calibration and standardisation:
Calibration is the process of determining the indicator error of a thermocouple and creating a correction value by comparing it to a high-precision reference in accordance with calibration criteria. It is a routine metrological activity that does not require obligatory verification. Thermocouple calibration for Husky temperature controllers incorporates the entire error compensation process.
Standardisation is a dynamic activity that requires high precision instrumentation. It directly adjusts for system flaws by measuring the divergence from a standard and assigning a graduation value to the instrument. It is mostly utilised in metrological reference equipment with high precision levels. It is not necessary for the usual maintenance of standard industrial thermocouples.
Operational logic in Husky scenarios: After completing the full calibration process for a Husky thermocouple, the error correction value has already been incorporated into the temperature controller's linear compensation parameters, effectively eliminating system temperature measurement variation. No more standardisation is necessary.
Only when the thermocouple's sensing element is totally replaced, or when the temperature controller's primary control board is replaced with new hardware, is it required to repeat the entire calibration process, rather than simply standardisation.
In routine operation and maintenance, as long as calibration and accuracy verification follow the established cycle, the long-term stability of temperature measurement accuracy can be guaranteed, fully meeting the production process requirements of hot runner injection moulding.
This operational logic completely complies with industrial metrology standards and is also appropriate for the real operation and maintenance requirements of Husky hot runner temperature control systems, hence avoiding redundant processes.
