PT100 / PT1000 Wiring Options
2-Wire RTD
2-wire wiring provides a simple and economical RTD configuration. However, lead-wire resistance can affect the measured resistance and therefore the temperature accuracy, especially with longer cables.
3-Wire RTD
3-wire wiring is commonly used in industrial temperature measurement because it provides improved compensation for lead-wire resistance. It is also the standard wiring configuration for many EaseWise stock PT100 and PT1000 sensors.
4-Wire RTD
4-wire wiring provides the highest measurement accuracy by minimizing the influence of lead-wire resistance. It is recommended for laboratory instruments, precision measurement, calibration systems, and other applications where accuracy is critical.
PT100 and PT1000 sensors provide an analog resistance signal and normally require an RTD input module, transmitter, controller, or data acquisition system. Typical excitation current is approximately 0.3–1 mA for PT100 and 0.1–0.3 mA for PT1000 to help reduce self-heating.
PT100 / PT1000 Temperature Sensor Applications
- HVAC and refrigeration systems
