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 ...

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 ...

RTDs (resistance-temperature detectors) are the preferred sensor choices for designs requiring precision. Although RTDs are approximately linear over the limited temperature range of 0 to 100°C, these ...

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 ...

The RTDM12 Series of RTD temperature sensors have a molded (IP67) four-pin connector with M12 male thread. With a fast response time, the sensor is ideal for pressure-vessel applications, pressurized ...

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 ...
