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 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 articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

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 ...

This article discusses the history and design challenges for designing a resistance temperature detector (RTD)-based temperature measurementsystem. It also covers RTD selection and configuration trade ...

Before running a formal test with multiple resistance temperature detector (RTD) sensors, it is often necessary to calibrate and debug a data-acquisition system to verify basic functionality. The ...

Temperature transmitters are employed to transmit a signal from a temperature sensor, such as a RTD or thermocouple, to a control or measurement device. These temperature transmitters amplify and ...

Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...
