Tabela termopar tipo J

Abaixo disponibilizamos a nossa tabela para Tabela termopar tipo J e também algumas informações importantes necessárias para a utilização por técnicos em campo. Confira abaixo:

Identificação dos fios

Positivo (+): Fio azul

Negativo (-): Fio vermelho

Boas práticas da instalação do sensor

- Simples inversão: É importante ligar corretamente o positivo e negativo no instrumento digital pois a simples inversão poderá enganar visto que a temperatura ambiente será indicada corretamente, porém no processo de aquecimento haverá grandes discrepancias na medição.

- Separe fios de potência da instrumentação: Não utilize o mesmo eletroduto para os fios da potência/alimentação junto com os fios de instrumentação pois poderá ter influências eletromagnéticas gerando erros de medição/indicação.

- Cabos de compensação: Utilizar cabos de compensação adequados ao tipo do termopar observando a polaridade (ligar positivo com positivo, e negativo com negativo). Nunca utilize cabos de cobre para interligar o sensor ao controlador. Dúvidas? Nos pergunte!

- Filtros RC em contatores: Utilize filtros RC nas bobinas de contatores para reduzir a susceptibilidade a ruídos eletromagnéticos no instrumento digital.

Tabela mV x Temperatura (Tabela termopar tipo J)

A Tabela termopar tipo J abaixo indica a tensão em mV em função da temperatura desejada. Abaixo segue uma explicação de como utilizá-la:

Cada uma das linhas indica uma faixa de temperatura, com dez valores. Por exemplo, se você deseja saber a tensão em milivolts da temperatura -245°C, você deverá procurar a linha que tem o valor inteiro mais próximo (que é -240°C) e a coluna que têm a temperatura de -5°C pois -240°C – 5°C = -245°C. Veja que o valor em milivolts é de 6,377mV.

Exemplo de como utilizar a tabela para FAIXA NEGATIVA

Na faixa positiva (acima de 0°C), o processo é similar, veja um exemplo para a temperatura de 245°C. Veja que o valor em milivolts é de 9,950mV.

Exemplo de como utilizar a tabela para FAIXA POSITIVA
