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 ...
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.
An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1). That idea ...
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 Endress+Hauser iTHERM TrustSens hygienic RTD self-calibrates to verify in-line that the sensor is working as designed Endress+Hauser’s iTHERM TrustSens hygienic resistance temperature detector ...
In a typical resistance temperature detector(RTD) measurement application, the delta-sigma converter often is configured in a ratiometric topology using a constant current excitation source. Although ...
The Rosemount 0085 non-intrusive Pipe Clamp Sensor provides a simple, fast solution for adding temperature measurements—and increased process visibility—to areas where intrusive sensors are not ...
