Both the RTD itself and its accuracy must be considered when selecting the RTD sensor. The temperature range varies with element type, and theaccuracy denoted at calibration temperature (usually at ...

RTD sensors are available using two-, three-, and four-wire configurations, which differ in their use of sense wires (Fig. 1a, 1b, and 1c, respectively).

This article presents the design, implementation, and experimental evaluation of a novel measurement circuit for four-wire resistive sensors, such as resistance temperature detector (RTD) thermal ...
