Issues regarding the polarity of compensation wires for K-type thermocouples
Thread Content
How can the polarity of a K-type compensation wire be determined in a simple and straightforward manner? Frequent misconnections at the site lead to temperature deviations
K-type thermocouple compensation wires have their polarity indicated by color: generally, the red wire is connected to the negative terminal of the thermocouple (nickel-chromium/nickel-silicon), while other colors (usually green or white) are connected to the positive terminal. Ensuring proper connection according to the correct wire colors and polarity will prevent temperature reading errors caused by incorrect connections. In practical applications, it is best to refer to the instructions or markings provided by the manufacturer when making connections. .
