Design an RTD interface with a spreadsheet
Mar 9, 2025 Circuits

RTDs are the preferred sensor choices for designs requiring precision. Although RTDs are approximately linear over the limited temperature range of 0 to 100 °C, these sensors exhibit a slight but progressively more nonlinear temperature-versus-resistance characteristic as the measurement range widens...
