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, ...

Calibration resistors R4 and R5 along with the RT1 and RT2 RTD sensors can sink this current when the corresponding GPIO pin is driven low. When not used, the GPIO pins are tri-stated.

Multiplex Large RTD Sensor Arrays For Lower Parts Count Sept. 18, 2000 Resistance temperature detectors (RTDs) are among the most versatile and accurate of the commonly used temperature sensors.

Temperature sensor uses Nickel RTD technology The Nickel RTD temperature sensor has a linear positive temperature curve with almost twice the sensitivity of a Platinum sensor and can be supplied in a ...

National Instruments (Nasdaq: NATI) today announced the NI PXIe-4357 RTD module, the latest addition to its SC Express sensor measurement family for PXI Express. The high-performance module is ...
