RTD sensors will never exhibit behavior based on theoretical ideals, but understanding the fundamentals behind transmitter-sensor matching will enhance their accuracy Temperature is the most common ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...

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 ...

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 ...
