Multipoint thermocouple in single sheath design

Process refining is an integral part of operations in a petrochemical plant. As markets shift and regulations on emissions are put in place, operating efficiency becomes more important in order to achieve the highest output possible while minimising environmental impact. Accurately monitoring these conditions is necessary to ensure operations are running as smoothly and efficiently as they’re meant to. Advancements in technologies provide new process conditions and present challenging conditions for measuring instruments inserted into the process.

WIKA’s model TC96-L multipoint thermocouple provides operators with the opportunity for advanced reactor temperature profiling, while reducing the amount of measurement strings inserted into the process. Multiple thermocouple points, formed completely independent from one another, are housed inside a single heavy-duty sheath to make up a linear array measurement string.

In doing this, the amount of non-reactive material inserted into the process flow is reduced when compared to a bundle of standard single-point measurement strings. Combining multiple measurement strings into one process connection maximizes the measurement coverage while minimizing the number of entries into the vessel, saving time and money during vessel construction. Monitoring temperatures inside the vessel provides the unique ability to evaluate various aspects of the operation including process hot spots, channeling effects and maldistribution of the catalyst, among others.
