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 ...
Line of resistance temperature detector (RTD) sensors are designed for precise and repeatable measurements. A high signal-tonoise output increases data-transmission accuracy with greater distance ...
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 ...
The temperature coefficient of an RTD (resistance-temperature-detector)element is positive. Most stable, linear, and repeatableRTDs are of platinum-metal construction. You can usethe constant 0.00385Ω ...
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 ...
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 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 ...
The DTG-RTD100 Series thermometer features a backlit display with 25-mm digits that can be read as far away as 10.7m. Readings include, process, Min, Max, Alarm condition, and battery status. An ...
