An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1). That idea ...

The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

The nickel-thin-film RTD (resistance-temperature-detector) sensors provide a large change resistance in response to temperature changes at a lower cost than nickel wirewound RTD elements. The sensors ...

This work presents the design, implementation, and experimental evaluation of a novel measurement circuit for four-wire resistive sensors, such as RTD thermal sensors. The proposed circuit ...
