Type j is mainly still in use based on the widespread applications of old instruments calibrated for this type. Studying for the pe exam, everything seems to be a breeze, but i cannot for the life of me read a tc chart. Consideration for bare wire type j thermocouple applications:
Making sense of thermocouples and interfaces (Part 1)
It has a smaller temperature range and a shorter lifespan at higher temperatures than the type k.
Type k thermocouples are so popular because of their wide temperature range and durability.
Table 8 type j thermocouple thermoelectric voltage as a function of temperature (°f); Type j thermocouple (iron/constantan) is also very common. Check out most commonly used thermocouples here. Consideration for bare wire type j thermocouple applications:
It is quite stable as well as accurate.

Table 7 type j thermocouple thermoelectric voltage as a function of temperature (°c);
A type j thermocouple measures 22 5 mv read temperature by measuring millivolts type j thermocouple degree celsius thermocouple temperature measurements calculate thermocouple temperature. Positive leg = white, negative leg = red, outer sheath (jacket) = brown (thermocouple grade) or black (extension grade),. In stock and ready to ship. Type j thermocouple accuracy and calibration error.

21 rows type t copper / constantan type j iron / constantan.009.054.263.380.158.005.031.165.222. It is equivalent to the type k in terms of expense and reliability. Choose from our selection of type j thermocouples, including over 200 products in a wide range of styles and sizes. Specifically, i have a sample problem in a study guide where the measured voltage is 21.57 mv with a 20c junction and a type j thermocouple.
