Reference Material
|
|
|
| |
Your choices are...
|
|
|
| |
Platinum
|
|
The most common metal used for RTDs - for measurement integrity platinum is the element of choice.
|
| |
Nickel / Nickel Alloys
|
|
Very common metal used, economical but not as accurate as platinum.
|
| |
Copper
|
|
Occasionally used as an RTD element. Its low resistivity forces the element to be longer than a platinum element. Good linearity and economical. Upper temperature range typically less than 150 degrees Celsius.
|
| |
Other
|
|
Gold and Silver are other options available for RTD probes - however their low resistivity and higher costs make them fairly rare, Tungsten has high resistivity but is usually reserved for high temperature work.
