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 ...

Texas Instruments introduced a new temperature sensor family that offers ±0.1°C accuracy across a wide temperature range and helps simplify system design for industrial and medical applications. The ...

RTD sensors will never exhibit behavior based on theoretical ideals, but understanding the fundamentals behind transmitter-sensor matching will enhance their accuracy Temperature is the most common ...

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 ...

To maintain high resolution and accuracy within a transducer or sensor-based measurement system, the designer must exercise care . . .

A high precision and accurate RTD sensor measurement requires precise signal conditioning, analogue-to-digital conversion, linearisation, andcalibration. The typical design of an RTD measurement ...

The circuit features low-cost components, including OpAmps, switches, and resistors, integrated with a microcontroller for a precise measurement of the resistance of the sensor. The circuit eliminates ...

RTD Sensors (Resistance Temperature Detectors) are temperature sensors that contain a resistor that alters resistance value as its temperature changes.

Our Type K thermocouple at 25 ºC generates 1.0 mV. It has a long TC cable which does not show continuity, but 130 ohms resistance. Can you explain why this is occurring and how it can be fixed? A: One ...
