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 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 ...

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 ...

Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

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 ...

Line of resistance temperature detector (RTD) sensors are designed for precise and repeatable measurements. A high signal-tonoise output increases data-transmission accuracy with greater distance ...

There are several types of temperature sensors which can be used in a temperature system. The temperature sensor to use depends on the temperature range being measured and the accuracy required. Along ...

This file type includes high resolution graphics and schematics. In a typical resistance temperature detector(RTD) measurement application, the delta-sigma converter often is configured in a ...
