B-type thermocouple
Did you know?
Type-B thermocouples produce the same output at 0 °C and 42 °C, limiting their use below about 50 °C. The emf function has a minimum around 21 °C, meaning that cold-junction compensation is easily performed, since the compensation voltage is essentially a constant for a reference at typical room temperatures. See more A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a … See more Thermocouples ideally should be very simple measurement devices, with each type being characterized by a precise $${\displaystyle \scriptstyle E(T)}$$ curve, independent of any other details. In reality, thermocouples are affected by issues such as alloy … See more Wires insulation The wires that make up the thermocouple must be insulated from each other everywhere, except at the sensing junction.
