This article revisits the building blocks used in the design of many RTD-based temperature sensors and discusses the limitations that these impose on a sensor’s application. It then shows how to ...

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 ...

You can achieve accurate resistance-temperature-detector sensor measurements without having to resort to using a precision current source.

This software-controlled RTD emulator produces voltages that cover the output range of the sensor. It supports all three RTD wiring configurations and associated sense-wire configurations.

One way to obviate the nonlinear characteristic of an RTD sensor is to design analog hardware to perform the curve-fitting mathematics before any additional signal processing occurs. This approach is ...

The iTHERM TruSens temperature sensor from Endress+Hauser calibrates itself after every Sterilize in Place (SIP) operation. The self-calibration process functions in situ and provides the necessary ...
