- The Pt100<\/strong><\/em> is a resistive temperature sensor that measures temperature using the electrical resistance of a high-purity platinum wire. The electrical resistance varies with temperature, making it possible to measure temperature. The ohmic value is 100 \u03a9 at 0\u00b0C.<\/p>\n

Pt100s are accurate and stable over the long term, offering excellent linearity of measurement<\/strong>, This makes them ideal for high-precision temperature measurement applications. However, compared with thermocouples, they are more expensive, more sensitive to electromagnetic interference, have a more limited measuring range, and a slower response time.<\/p>\n

In conclusion, the choice between a thermocouple and a Pt100 will depend on the following factors specific needs of YOUR application<\/strong>. To make the right choice, get advice and support from a measurement specialist. For over half a century, MESUREX has specialized in the design & manufacture of custom temperature sensors.<\/p>\n

In the field of temperature measurement, the two most commonly used technologies are the thermocouple<\/strong><\/span> and the Pt100<\/strong><\/span> (also known as RTD - Resistance Temperature Detectors).<\/h4>\n
- The thermocouple<\/strong><\/em> is a sensor that measures temperature using the difference in electrical voltage generated by two different metals connected together (SEEBECK effect). As the temperature changes, so does the voltage, making it possible to measure temperature.<\/p>\n
The advantages of thermocouples are undeniable: low cost, small size, robustness, measurement responsiveness and wide measuring range<\/strong> (download the summary on \u00ab How to choose a thermocouple<\/a> \u00bb). They are commonly used in high-temperature applications and harsh environments. However, their accuracy is less than that of Pt100s, and their response can be affected by probe length and connection quality.<\/p>\n
