	for clarification, to terminate the T/C (Type K) extension wire between the element and transmitter side used the crimping lugs (as the core is multistrand) at both end. will it affect the accuracy of reading? as it's carries only mV signal. the introduced the new matel (i.e lugs) will affect the signal?

	PW is right, of course, in an abbreviated sort of way. However, I think another consideration is worth mentioning. Thermocouple extension wire is very susceptible to external interference such as high voltage power EMI. Make sure you separate the two, especially on long runs. You might even want to convert that MV signal to an analog current such as 4-20 mA. Here's an example of something that I've used before. (http://www.redlion.net ITMA temperature inputs) P.S.
