There are 4 high-temperature thermocouples at the GE gasifier site, but the DCS shows 3 temperature readings for each thermocouple. Why is that?

What is the calibration type of your thermocouple, and is it multi-core?

It’s possible that you created 3 identical points on DCS

There is a thermocouple at the site; on the DCS, the same thermocouple is divided into A, B, and C categories, with the readings differing by 50 to 100

Multi-point thermocouples: one with three points, and judgments are made based on values following a certain pattern; if two of them show a value above 100 degrees, a signal is sent

Multi-core, possibly also for 2oo3 considerations~
