Download Technical notePrecision and reliability are of the utmost importance in the validation of thermal processes. These requirements demand time-consuming and complex procedures for the validation, calibration, and verification of the instruments used. In this context, the Kaye IRTD, a high-precision traceable temperature standard, plays a noteworthy role. Its application is crucial for the accuracy of Kaye’s validation systems, like the Kaye AVS and the Kaye ValProbe, and thus forms an integral part of these verification and calibration processes. However, the use of temperature standards also brings specific challenges and potential risks. This Technical Note shows how such risks can be minimized, and the validation and calibration processes can be optimized and have their risks reduced.
Download Technical noteEmbedded sensors have become widely adopted across industries — from food processing to pharmaceutical sterilization — due to their flexibility and ease of use. However, ensuring their metrological accuracy remains a critical challenge in thermal validation, especially in the absence of dedicated standards. This Technical Note explores common calibration strategies, outlines practical risk assessments, and provides guidance on optimizing accuracy using traceable tools such as the Kaye IRTD. Learn how to confidently manage embedded sensor calibration and strengthen compliance in regulated environments.
