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 ...

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 ...

Temperature is one of the most widely measured parameters in a power plant. No matter the type of plant, accurate and reliable temperature measurement is essential for operational excellence.

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 ...

To maintain high resolution and accuracy within a transducer or sensor-based measurement system, the designer must exercise care in selecting the excitation source for the transducer — and the ...

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 ...
