The description of thermocouple Pt1000:
As for the thermocouple, we split the word: Pt and 1000. Pt is the chemical symbol for Platinum, 100 is the resistance in Ohm of the Pt1000 at 0 °C. The resistance changes (fearly linear) with temperature are: 0.385 Ohm/°C for European and 0.392 Ohm/°C for American elements. So, by measuring the resistance we can calculate the temperature. Never use a European Pt100 with an American instrument unless you know that it is set for the right conversion factor (usually called 'alpha'). In english a Pt1000 is also called a RTD element, meaning Resistance Temperature Detector.
An RTD or Pt1000 sensor is connected with two, three or four wires to the measuring device. we learned that we are in fact measuring resistance to determine the temperature. Now when measuring the resistance of the sensing element, we also measure the resistance of the leads and cables used. This gives an error! To compensate for this, the three wire type (bridge) is used, giving enough accuracy in most industrial applications. Even better accuracy is possible with a four wire Pt1000 (laboratory applications). Our Pt1000 panel mounted indicators have an offset compensation when using two wire sensors.
If you want high accuracy, for example better then 0.5°C between 0 and 100°C, go for the Pt1000.
