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 ...

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 ...

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 growth of the resistive temperature detector (RTD) temperature sensor market is driven by the rising demand for high-accuracy temperature measurement across industrial automation, energy, and ...

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 ...

From thermocouples and thermistors to resistance-temperature-detectors (RTDs), temperature sensors are varied and ubiquitous, but it would be wise not to take them for granted. Each type comes with ...

In this first article in a two-part series, we discuss resistance temperature detector (RTD) circuit design for a functionally safe system and introduce considerations for the Route 2S component ...

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 ...
