Abstract

The majority of measurements made in process industry are of temperature and pressure. Temperature measurements are used in particular to secure product quality, increase process efficiency and ensure plant safety. Suitable temperature measurement instruments are widely available and the cost of these has decreased over time due to high volumes, technological progress and competition. However, these devices are mostly intrusive in nature. Noninvasive, wireless and energy-autonomous temperature sensors have the potential to substantially change the practice of industrial temperature sensing. In this article, a successful implementation for such an instrument is provided, covering an optimized, experimentally validated thermomechanical design, a model-based correction accounting for inherent measurement errors, and a pilot installation at an end customer plant.
