Um sensor resistivo do tipo PTC (Coeficiente de Temperatura Positivo) é um componente elétrico que mede a variação da resistência elétrica em função da temperatura. Esses sensores são amplamente utilizados como sondas de temperatura em aplicações industriais, em aparelhagem médica, em eletrodomésticos, em instrumentação para investigação científica, no setor automobilístico, em telecomunicações, em aplicações militares etc. A figura a seguir representa uma curva característica de uma medição de um sensor PTC de modelo B59213J0130A020.
