Regarding the resistor rod issue

What are the differences in usage between Pt100 and Pt50 platinum resistors?
This post was last edited by devil_ytw on 2010-4-20 at 14:07. Pt50 has a higher temperature resistance than Pt100, allowing it to measure higher temperatures
The poster is probably referring to CU50. The temperature range for CU50 is -50 to 150 degrees, with low accuracy; the temperature range for PT100 is -200 to 850 degrees, offering higher accuracy, but it is more expensive than CU50
