## What Equation Should I use for a RTD Data Logger?

Microedge produces three models of RTD data loggers for different RTD sensors: LRTD-1 for PT100 LRTD-2 for PT500 LRTD-3 for PT1000 Depending on the RTD sensor you are using you can use the following two embedded equations: RTD_TCR385:This equation is for Temperature Coefficient of Resistance (TCR) 0.00385Ω/Ω/°C . The temperature coefficients are: A: 3.9083E-3 B:…
