Thermocouples are temperature sensors. Different thermocouple types have different voltage output curves, so using the correct thermocouple type is essential to getting accurate measurements. Thermocouple Selection Factors to consider when selecting the appropriate thermocouple for your application include: the original equipment thermocouple type, the application temperature, required length of service, required degree of accuracy, proper selection of extension wire type, chemical resistance of the thermocouple and/or sheath material and cost. Be aware that large errors in measurements can occur if the proper type of extension wire is not used. The extension wire is the wire that connects the thermocouple probe to the measuring element (meter, […]
