XIQI Electric CG-WZP-035 PT100 RTD Sensor, 5x30mm Stainless Steel Probe, 0.5m Three-Wire PTFE Cable

The three-wire configuration allows for compensation of lead wire resistance, which can introduce significant measurement errors, especially over long cable distances. By using three wires, the measuring instrument can subtract the resistance of two identical leads, providing a much more accurate reading of the actual sensor resistance and, therefore, temperature.

Yes, but it requires an intermediate signal conditioning circuit or module. A PT100 sensor outputs a resistance change. You will need a dedicated RTD amplifier or analog front-end module (e.g., with a Wheatstone bridge and instrumentation amplifier) to convert the small resistance changes into a voltage readable by a microcontroller's ADC. Direct connection is not possible.

Yes, PTFE (Teflon) insulation is specifically chosen for its excellent thermal stability, chemical inertness, and moisture resistance. It can withstand continuous temperatures typically exceeding 200°C and is resistant to most industrial chemicals, making it ideal for routing the sensor signal through hot or corrosive areas near the measurement point.

A PT100 is an RTD (Resistance Temperature Detector) that uses the predictable change in platinum wire resistance. It generally offers higher accuracy and stability over a narrower range (like 0-800°C) compared to thermocouples. Thermocouples generate a small voltage from the junction of two dissimilar metals and are typically used for wider, higher-temperature ranges but may require cold-junction compensation and can be less stable.
