What do these two gauges connected here indicate? ?

Temperature sensors (thermocouples or thermal resistors) are installed on-site, and their signals are sent to the control room where temperature readings are displayed on the DCS. The signal connection between TE and TI has been omitted.
This should be computer-controlled instruments and a control room
It is generally considered to be just a thermometer on-site + remote transmission
On-site and remote temperature monitoring; this is now a standard feature of DCS operating systems
Temperature at the site (primary element) + remote transmission (DCS)
TE0101 indicates that there is a thermal resistor somewhere in the flowchart, while TI0101 indicates that there is a temperature indicator in the system.
Those with boxes are remote meters, while those without them are on-site meters; it’s the same for all of them
Thermometer: on-site + remote transmission only
