The temperature coefficient of Pt100 sensors is approximately 0 385 Q K The resistance of a 10 m sen sor cable with a cross section of 0 5 mm is about 0 712 Q and distorts the measuring result by nearly 2K The temperature depending change of the cable resistance and the contact resistance have to be additionally considered The temperature coefficient of Pt1000 is 10 times higher in comparison to Pt100 According to that the influence of cable and contact resistance is 10 times smaller There are resistive temperature sensors with even higher temperature coefficients e g NTC sensors Note Chose temperature sensors with temperature coefficients as high as possible in order to minimize the influence of systematic errors We recommend sensors of appropriate type preferable NTC and or with a nominal resistance of at least 1000 Q with Ni or Pt 1 2 Tolerance and Drift The influence of measuring errors which are caused by tolerance and drift of the measuring device can be reduced by proper choice of measuring mode and sensor type Basically the same recommendations as with systematic errors have to be considered Table 5 2 1 shows an overview of tolerance and drift of the several measuring modes Table 5 2 2 con tains an overview of the temperature coefficients of selected sensor types With this information it can be estimated which errors can be caused by a certain combination of measuring mode and sensor type Note Regard 3 2 in or
