Pt100 RTD selection in 2026 hinges on six process-driven criteria: sensing-element class (thin-film vs wire-wound), sheath material, lead configuration (2/3/4-wire), accuracy class per IEC 60751, process connection plus thermowell, and hazardous-area certification. Match these to the loop before quo
Thermocouples measure internally with a junction seated in or on the target; infrared thermometers read surface temperature from radiated IR without contact — distinct physics drives their selection, accuracy, and limits.
A temperature transmitter and an RTD Pt100 are not competing devices: the Pt100 is the sensing element, and the transmitter is the electronics that converts the Pt100's low-level resistance change into a 4–20 mA or digital signal. Specifying one without the other leaves either a raw ohm signal or a
Temperature transmitter selection hinges on four sensor-side decisions — input type (RTD vs thermocouple vs thermistor), output protocol (4-20 mA, HART, Foundation Fieldbus, wireless), hazardous-area certification, and diagnostics depth — before the loop, housing, and accuracy class are even discuss
