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 ...

The final impetus for this project came from the discovery of some long-mislaid PT100 RTD sensors, which enabled something fairly precise: a box to convert the RTD’s resistance into a millivolt signal ...

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 ...

Further, its operating temperature range of -55°C to +160°C makes it application-compatible with requirements for the use in motor oil and hydraulic systems. Measurement Specialties has the capability ...

where: R RTD is the measured RTD resistance. V ADC is the ADC voltage reading. I CC is a somewhat constant-current source. V Offset is the voltage offset of cumulative errors. Note that this ...

RTD sensors are available using two-, three-, and four-wire configurations, which differ in their use of sense wires (Fig. 1a, 1b, and 1c, respectively).

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 ...

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.
