Evertiq - Overvoltage protection for RTD-based measurement ysstems
Overvoltage protection for RTD-based measurement ysstems Question: Is it possible to design a complete RTD module with overvoltage protection? Answer: RTD (resistance temperature detectors) can provide excellent stability and accuracy, and reduce the impacts of noise and interference. RTD sensors can be made up of either 2-wire, 3-wire, or 4-wire versions, and require an excitation current to produce an output voltage. AD7124-4/AD7124-8 contain two well matched current sources, a PGA, reference...
