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 ...

The four-wire configuration consists of two current leads and two potential leads that measure the voltage drop across the RTD. The two potential leads are high resistance to negate the effect of the ...

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 ...

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 ...
