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 ...

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 ...

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 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 ...

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 ...

RTDs (resistance-temperature detectors) are the preferred sensor choices for designs requiring precision. Although RTDs are approximately linear over the limited temperature range of 0 to 100°C, these ...

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. Omega’s new RTDM12 series of ...
