Introduction to the platinum thermal resistance

Introduction the platinic resistance heat resistance is the application of platinum wire resistance changes with temperature changes the fundamental principle of design and manufacturing, according to 0 ℃ resistance R ( ℃) The size of the divided into 10 ohm ( Index number for Pt10) And 100 ohm ( Index number of Pt100) Such as, temperature field are - 200~850℃. Original 10 ohm platinum thermal resistance of heat is using coarser platinum wire winding and become, heat-resistant function distinctly better than platinum thermal resistance of 100 ohms, only used for above 650 ℃ temperature area: 100 ohm platinum thermal resistance is important for the temperature under 650 ℃, although also can be used in the temperature range of 650 ℃ above, but in the temperature range of 650 ℃ above are not allowed to have A level of error.

100 ohm platinum thermal resistance of the resolution of the resolution of the platinum thermal resistance than 10 ohms 10 times larger, corresponding to a request for secondary instrument to a level number, so the temperature range of under 650 ℃ temperature should choose 100 ohm platinum thermal resistance, to ensure that the work efficiency.
