1. Tolerance is defined as the maximum allowable deviation from the temperature vs. | |
resistance reference table | |
2. ltl = modulus of temperature in degrees Celsius without regard sign. |

Two-conductor type : Since a conductor resistance is added to the resistance value, it is necessary to reduce the conductor | ||
conductor in advance. This type is not usually used, except for a high resistance RTD's | ||
Three-conductor type : Use to eliminate the effect of conductor resistance, care should be taken for long-distance fransmisson | ||
because a variation of resistanceconductors has an effect on accuracy. this type of connection is most | ||
widely ysed in industrial applications. | ||
Four-conductor type : This type of connection is used for high-accuracy measurement and standards because it is not | ||
affected by conductor resistance. Generally, a constant is applied and the resistance value is | ||
measured by a potential difference. |
