Standard pair alloy wire and insulating materials are chosen to match the measured 

temperature range, maximum temperature and environmental conditions expected. 

Time response and durability affect the choice of wire size. Some materials will melt 

at high temperatures and some insulating materials are not waterproof. Tables and 

algorithms are available for calculating temperature differences for standard alloy 

pairs.
