TST434B

A Resistance Temperature Detector (RTD) measures temperature based on the principle that the electrical resistance of a metal conductor changes with temperature. The fundamental principle is that when temperature changes, the lattice vibration of metal conductors such as platinum and copper changes, affecting the resistance to electron movement and causing the electrical resistance value to vary accordingly. Taking the Pt100 platinum resistance sensor as an example, its standard resistance is 100 Ω at 0 °C. The resistance increases by approximately 0.385 Ω for every 1 °C rise in temperature, exhibiting a highly linear relationship within a defined temperature range. In practical measurement applications, a constant current source or bridge circuit converts resistance variations into electrical signals. Three-wire or four-wire connection technology is used to eliminate lead resistance errors, and the resistance value is finally converted into temperature according to internationally standardized resistance-temperature tables.
