An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

Temperature is one of the most frequently measured physical quantities, and features prominently in many of our projects, from weather stations to 3D printers. Most commonly we’ll see thermistors, ...

Bridge circuits have long been popular for conditioning signals from resistive sensors. These circuits are sensitive to small changes in resistance, and they provide a differential output from a ...

This product is featured in EDN's Hot 100 products of 2017. See all 100 here. Measuring high current in circuits such as DC power supplies requires shunt resistors. Unfortunately, those resistors ...

You can characterize a semiconductor device to be its own temperature sensor by using an accurate four-wire measurement technique. Semiconductor junctions — from the millions of transistors used in ...
