O sensor PT100 mede a temperatura pela correla\u00e7\u00e3o da sua resist\u00eancia el\u00e9trica com a temperatura. A maioria destes sensores \u00e9 constru\u00edda a partir de uma espiral de fio fino montada num suporte cer\u00e2mico, de vidro ou filme pl\u00e1stico.
O PT100 \u00e9 considerado o mais exato sensor de temperatura industrial dispon\u00edvel, al\u00e9m de proporcionar excelente repetibilidade.
Podem ser fornecidos simples com liga\u00e7\u00e3o a 2, 3 ou 4 fios e dupla com liga\u00e7\u00e3o \u00e0 4, 6 ou 8 fios e tamb\u00e9m com transmissor de sinal com sa\u00edda 4 a 20mA.<\/p>\n\n\n\n

Na medi\u00e7\u00e3o de temperatura com termorresist\u00eancia \u00e0 2 fios temos uma dist\u00e2ncia limitada entre o sensor e o instrumento receptor, dada pela bitola dos condutores. J\u00e1 \u00e0 3 ou 4 fios esta dist\u00e2ncia \u00e9 praticamente ilimitada.<\/p>\n\n\n\n
