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, ...

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 20mA ...

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 ...

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 ...

The nickel-thin-film RTD (resistance-temperature-detector) sensors provide a large change resistance in response to temperature changes at a lower cost than nickel wirewound RTD elements. The sensors ...

The iTHERM TruSens temperature sensor from Endress+Hauser calibrates itself after every Sterilize in Place (SIP) operation. The self-calibration process functions in situ and provides the necessary ...

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 ...

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 ...

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.
