For precise temperature measurements, a 3-terminal sensor is commonly used. This configuration minimizes the effects of lead resistance, providing more accurate readings in industrial and laboratory settings. To ensure optimal performance, connect the three terminals as follows: one for the measurement input, one for the reference, and the third for the excitation. This setup compensates for the resistance of the connecting leads, which can otherwise skew results in long-distance installations.
