These thermocouples can cover the needs of nearly all
industrial temperature measurements.
The most commonly used thermocouples are copper -
with a range from -180ºC to + 400ºC, iron
- constantn "J",
ranging from 0ºC to 800ºC and nickel chromium
- alloyed nickel "K",
ranging from 0ºC to 1.150 ºC which has a slightly
lower sensibility than types T and J but its generalization
in a factory could simplify spare parts problems.
