Is stranded wire less efficent to use then solid wire? Error, voltage drop, etc? We currently use solid but it has been breaking often in screw terminals.

Asked by: jpvance
Hey, thank you for your question. In short, no. Stranded wire is no less or more efficient to use in comparison to solid wire. Both wire options are tested and expected to meet the same requirements.

Can I order 100 foot wire instead of 1000

Asked by: Burnie
Thank you for your inquiry Burnie. Yes you can. The part number for the 100 ft of EXPP-K-20S wire would be EXPP-K-20S-100. Please review the specs on the website before placing the order.

What does SLE (Special Limit of Error) actually mean?

Asked by: Bret
Thank you for your inquiry. The sensor meets or exceeds the tolerance level that are defined for special limits of error wire. In this case, type K has tolerance +/- 1.1C when using SLE material

I need K type extension wire to used for temperature up to 700 F. Can you tell me which one that I can use?

Asked by: ImpCare
Thank you for your inquiry! None of our K type extension wire is rated for temperatures this high. Thermocouple grade wire with fiberglass insulation can be used instead which will allow for use up to 900F. https://www.omega.com/en-us/temperature-measurement/temperature-wire-and-cable/thermocouple-wires/xc-k-tc-wire/p/GG-K-20-50
