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 ...

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 ...

The vendor’s ProSense line of process sensors now includes 0.25-inch RTD temperature probes. The three-wire, 100 ohm platinum RTD probes are made of durable 316 stainless steel and measure ...

This software-controlled RTD emulator produces voltages that cover the output range of the sensor. It supports all three RTD wiring configurations and associated sense-wire configurations. Before ...

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 ...

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 ...

Temperature is by far the most commonly measured physical parameter. With so many new ideas for connected devices in the works for consumer and industrial applications, you often need high-accuracy ...

Palmer-Wahl Instrumentation Group has introduced a new series of Italcoppie-brand RTD probes that the company says offer long-lasting, accurate temperature measuring in harsh operating conditions and ...

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 ...

Temperature is one of the most widely measured parameters in a power plant. No matter the type of plant, accurate and reliable temperature measurement is essential for operational excellence.

Thermistors use a thermally active resistor made of metal oxides encased in epoxy or glass. The resistance output varies based on temperature. A more accurate thermister will vary linearly throughout ...
