Publications on RadioLocman by the author John Wynne:
- RTDs provide differential temperature measurementYou sometimes need to measure the differential temperature between two points in a system to a greater accuracy than that required in measuring the absolute temperature at either of the individual points....Dec 15, 2025
- Current source allows measuring three-wire RTDJohn Wynne EDN In applications in which you need remote measurement of temperature with a three-wire RTD (resistance-temperature detector), it is important to eliminate the ohmic errors caused by the excitation...Dec 12, 2019
- Eliminate thermoelectric EMF in low-ohm measurementsWhen two different-metal conductors connect together in a loop and one of the junctions is at a higher temperature than the other, an electrical current flows through the loop. The magnitude of this current depends on...Nov 29, 2017
- CMOS DACs act as digitally controlled voltage dividersDigital potentiometers, such as Analog Devices’ AD5160, make excellent digitally controlled voltage dividers in applications in which 8-bit resolution is acceptable. This Design Idea shows how to use a CMOS DAC as...Nov 18, 2016
