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 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 ...
Both the RTD itself and its accuracy must be considered when selecting the RTD sensor. The temperature range varies with element type, and the accuracy denoted at calibration temperature (usually at ...
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 ...
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 ...
The Omni RTD temperature sensor is a combination of an integrated display/control unit and a highly accurate platinum RTD temperature-sensor tip. A user-programmable display interface permits setting ...
