This article discusses the history and design challenges for designing a resistance temperature detector (RTD)-based temperature measurementsystem. It also covers RTD selection and configuration trade ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...

Unlike the 2- and 3-wire transmitter representations shown in Figure 2, the 4-wire circuit has separate paths for the power current and signal current. Also, the 4-wire receiver does not share a ...

Before running a formal test with multiple resistance temperature detector (RTD) sensors, it is often necessary to calibrate and debug a data-acquisition system to verify basic functionality. The ...
