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 ...

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 ...

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 ...

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 self-calibration process functions in situ and provides the necessary documentation to meet the conformance requirements of regulatory agencies. It eliminates the risk of an undetected calibration ...

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 ...

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 ...

Designers face many chal lenges when placing thermal-sensing components in embedded systems. The first comes in choosing the temperature sensor. It is often not obvious whether a thermistor, resistive ...

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 ...

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 ...
