INTRODUCTION Temperature devices in process manufacturing environments provide measurements to the process plants’ control systems. The performance of these temperature instruments is often critical to optimised operation of the process manufacturing plant or proper functioning of the plant’s safety systems. Process temperature instruments are often installed in harsh operating environments, causing their performance and the performance of their sensors to shift or change over time. Keeping these devices measuring temperature within expected limits requires periodic verification, maintenance and adjustments.
