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 ...

A platinum RTD provides the best performance because platinum has the most linear and repeatable temperature-to-resistance relationship over a large temperature range. For a typical platinum resistor, ...

Resistance temperature detectors (RTDs) are among the most versatile and accurate of the commonly used temperature sensors. However, the typical RTD’s temperature response consists ...

A few simple components are all it takes to create an over-temperature alarm. The circuit in Figure 1 requires only an ordinary negative-temperature-coefficient (NTC) thermistor, two common ICs ...
