Measuring resistors
There are 3 different types of measuring resistors which have different characteristics:
- Flat measuring resistors
consist of a ceramic substrate and a structured platinum layer.
Advantage: very inexpensive
Disadvantage: limited stability, only in limited temperature range, relatively small measuring range.
- Ceramic measuring resistors
consist of a ceramic tube on which a thin platinum wire is wound, protected by a ceramic coating.
Advantage: stable, large measuring range
Disadvantage: expensive
- Glass measuring resistors
Structure like ceramic measuring resistors, but all made of glass
Advantage: highly stable
Disadvantage: expensive, smaller measuring range than ceramic measuring resistors but larger than flat measuring resistors.
