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 ...

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 ...

Resistance temperature detectors (RTDs) are among the most versatile and accurate of the commonly used temperature sensors. However, the typical RTD’s temperature ...

Endress+Hauser’s iTHERM TrustSens hygienic resistance temperature detector (RTD) is a self-calibrating temperature sensor that can be used in bio/pharma processes to eliminate the risk of undetected ...

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. Before ...

Omega’s new RTDM12 series of compact RTD temperature sensors are extremely rugged with a molded (IP67) 4-pin connector with M12 male thread and a fast response time.
