2, 3, and 4 Wire RTDs: What is the Difference?
RTD wiring configurations There are three types of wire configurations, 2 wire, 3 wire, and 4 wire, that are commonly used in RTD sensing circuits. A 2-wire configuration with a compensating loop is also an option. 2 wire RTD connections The 2 wire RTD configuration is the simplest among RTD
RTD Sensors Operation & Maintenance Instructions - Temperature
A RTD Sensing element consists of a wire coil or deposited film of pure metal. The element’s resistance increases with temperature in a known and repeatable manner. RTD’s exhibit excellent accuracy over a wide temperature range. Temperature range: -200 to 700ºC
Connecting 2, 3, and 4 Wire RTDs to My Data Acquisition
The following connection diagrams illustrate how to connect various RTD types to your DAQ device. 4-wire RTD Signal Connection Connect each of the red leads on the positive side of the resistive element to the excitation positive and channel positive on the DAQ device.
RTD Theory - Pyromation
PDF file4-wire construction is used primarily in the laboratory where close accuracy is required. In a 4 wire RTD the actual resistance of the lead wires can be determined and removed from the sensor measurement. The 4-wire circuit is a true 4-wire bridge, which works by

2-Wire Circuit wired to a 3-Wire or a 4-Wire Circuit. If necessary you can connect a 2-wire RTD to a 3-wire circuit or 4-wire circuit, as shown. As long as the junctions are near the RTD, as in a connection head, errors are negligible.
Common RTD Application Problems and their Remedies
RTD sensor in 2-wire circuit; the connection lead are subjected to a large temperature change. (1) Convert to 3-wire circuit, which will essentially eliminate the ambient temperature effects (2) Convert to a 4-wire circuit - in this case connection lead resistance effects completely eliminated.
2 Wire RTD - Wiring a 2 Wire RTD
2 Wire RTD Wiring Diagram Shown is a 2-wire RTD connected to a typical Wheatstone bridge circuit. Es is the supply voltage; Eo is the output voltage; R1, R2, and R3 are fixed resistors; and RT is the RTD.
Compact I/O RTD/Resistance Input Module User Manual, 1769
PDF fileEach channel is individually configurable via software for 2- or 3-wire RTD or direct resistance input devices. Channels are compatible with 4-wire sensors, but the fourth sense wire is not used. Two programmable excitation current values (0 and 1) are provided, to limit RTD self-heating. When configured for RTD inputs, the module can

In two wires RTD Bridge, the dummy wire is absent. The output taken from the remaining two ends as shown in fig.3. But the extension wire resistances are very important to be considered, because the impedance of the extension wires may affect the temperature reading.
