PT100 or PT1000: How to Choose
Overview Both are platinum RTDs with the same resistance–temperature curve; the difference is the resistance at 0 °C — 100 Ω versus 1000 Ω. The choice is really…

Read more→Overview Mineral-insulated thermocouples are chosen for their combination of flexibility, fast response and mechanical strength. Five decisions cover almost every application. Key Points 1. Calibration type. Set by…
Read more→Overview A platinum RTD measures temperature through the predictable change of platinum resistance. PT100 sensors have 100 Ω at 0 °C; the resistance–temperature relationship is defined by IEC…
