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 ...

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 ...

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 ...

Accurate measurement using sensor elements requires precise and local measurement of the element’s temperature for correction and compensation across a wide operating range. Thus, an integral part of ...

The two most common types of temperature sensors in industrial applications are resistance temperature devices (RTD) and thermocouples. Choosing correctly can be crucial to the success of your ...

Starting with the sensor, measuring and controlling temperature is an essential building block of process industries. Automatic control in continuous processes uses industrial control systems to ...
