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 ...

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 ...

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 ...

IC 1 is pin-configured to drive a constant current of 400 µA through the grounded sensor, T 1 . Driving T 1 with this level of current—“zero-power” operation—keeps the worst-case power that the ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually ...

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 ...

It is an Application and Industry Solution (AIS) sensor for surface measurements in process and oil & gas industry applications such as pipelines and wellheads. It is mounted directly on the pipe ...
