When it comes to industrial temperature measurement, RTD temperature sensors (Resistance Temperature Detectors) are a go-to choice for engineers and designers seeking accuracy, stability, and reliability<\/span>.<\/span>  <\/span>Among the most common RTDs are <\/span>the<\/span> Platinum<\/span> RTDs<\/span>. W<\/span>ithin th<\/span>is<\/span> family, <\/span>the<\/span> PT100 and PT1000<\/span> are the<\/span> most common<\/span> resistance values<\/span>. B<\/span>oth <\/span>are<\/span> known for their precision and long-term stability. But <\/span>what\u2019s<\/span> the real difference between them? And when should you choose one over the other?<\/span><\/span> <\/span><\/p>\n<\/div>\n

Both PT100 and PT1000 RTDs use platinum as the sensing element, known for <\/span>their<\/span> consistent temperature-resistance relationship. <\/span>Both have Temperature <\/span>Coefficient<\/span> of Resistance (TCR) values of 0.00385 \u03a9\/\u03a9\/\u00b0C. <\/span>The key<\/span> electrical<\/span> difference lies in their nominal resistance<\/span> at 0\u00b0C:<\/span><\/span> <\/span><\/p>\n<\/div>\n
