Thermocouple wiring issues
Thread Content
Hello everyone! I have a question: The wiring box of the thermocouple WRE2—240M contains four terminals. How should I wire it?
The thermocouple WRE2—240M is a dual‑element “E” type thermocouple； The resistance setting on a multimeter can be used to determine which two terminals form a pair.
Just measure it and figure out the relationship between these four wires, and then you’ll be able to connect them, right?
The WRE2-240M thermocouple is an E-type two-wire thermocouple; use a multimeter to check whether there is a connection, and also measure its millivolt value. Will it be connected soon?
What was said on the second floor is very correct and clear.
What was said on the second floor is right – those who work with instruments should always carry a multimeter, and even if they do, they still need to use it...
Friendly reminder: Be careful not to reverse the positive and negative sides...
Reply to 3# oqyong: Use a multimeter to check it; the two terminals that are connected form one group. Determine their polarity as well, and match it with the polarity of the compensation wire. That’s all
It can be determined to be a dual-element thermocouple; there are also multi-element types used in practical applications, and all of them can be identified using the following method: A multimeter can be used for this purpose – the resistance setting is used to identify the groups of elements, while the voltage setting is used to determine the positive and negative terminals, thereby completing the wiring process.
I haven’t encountered it, but I’ve benefited from it.
That’s right; a multimeter will do the trick.
