As with many two-wire resistance measurements, an RTD's lead wires have resistance and long lead wires will greatly affect the measurement accuracy. Therefore, the actual resistance measured by the ...

An RTD is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature.

The circuit uses the popular Pt100 RTD, which has a resistance of 100 Ω at 0°C. Its temperature coefficient of 0.00385 Ω/Ω/ºC produces a 38.5-Ω increase in resistance from 0°C to 100°C. Thus, the ...

In a typical resistance temperature detector (RTD) measurement application, the delta-sigma converter often is configured in a ratiometric topology using a constant current excitation source.

Acromag’s newest addition to the Busworks® NT Series of expandable remote Ethernet I/O modules is the NT2620 Series RTD/resistance module. Designed to be a cost-effective modular solution, it supports ...

Rosemount 3144S Temperature Transmitter offers 0.05-degrees Celsius accuracy, 20-year stability, advanced diagnostics and ...

You can characterize a semiconductor device to be its own temperature sensor by using an accurate four-wire measurement technique.
