The measurement of the temperature of RTD is based on the properties of the electrical conductors to alter its resistance depending on the temperature . Most wire increases its resistance with increasing temperature and decrease with decreasing temperature . RTD types : Pt 100 by a factor of 1.385 (range -200 ÷ 850 ° C ) - IEC 751 Pt 100 by a factor of 1.391 (range -200 ÷ 650 ° C) - 22 graduations Pt 46 (range -200 ÷ 650 ° C) - 21 graduations Cu 53 (range -50 ÷ 180 ° C) - graduation 23 Cu 100 (range -50 ÷ 180 ° C) - graduation 24 Ni 100 (range -60 ÷ 250 ° C ) - DIN 43760 , Cu 50 (range -50 ÷ 200 ° C) Pt 50 (range -260 ÷ 750 ° C)
