Conclusion Selecting the correct RTD or thermocouple for an application will enhance performance and prevent sensor damage. Thermocouples are a multipurpose and cost-effective means of temperature ...

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 ...

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 ...

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 ...

The temperature coefficient of an RTD (resistance-temperature-detector)element is positive. Most stable, linear, and repeatableRTDs are of platinum-metal construction. You can usethe constant 0.00385Ω ...

where: R RTD is the measured RTD resistance. V ADC is the ADC voltage reading. I CC is a somewhat constant-current source. V Offset is the voltage offset of cumulative errors. Note that this ...
