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 ...

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 ...

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 ...

Temperature is one of the most frequently measured physical quantities, and features prominently in many of our projects, from weather stations to 3D printers. Most commonly we’ll see thermistors, ...

Temperature transmitters are employed to transmit a signal from a temperature sensor, such as a RTD or thermocouple, to a control or measurement device. These temperature transmitters amplify and ...
