The flue gas temperature of the boiler and other applications in the field of high temperature measurement can be measured using temperature sensors equipped with a thermocouple sensor.
Thermocouples can be measured with the C-IT-0200I module (see the following example),
or we can use the analog input module IT-1605 (peripheral module of the Foxtrot system on the TCL2 bus),
or with a smaller requirement for accuracy (eg measuring the boiler flue gas temperature) we can use the analog inputs of the basic module CP-10x8.
Fig. 1 Example of C-IT-0200I module connection, connection by thermocouple temperature sensor
We connect the thermocouple sensor directly to the terminals of the C-IT-0200I module with a compensation line. The cold end compensation of the thermocouple is solved by the module using an internal temperature sensor.
