Four-wire PT100 RTD measurement circuit with low-side reference Using the maximum RTD resistance, the ADC input voltages are calculated in the following: VAIN1 = IIDAC1 • (RRTD + RREF) = 1mA • (400Ω+ 1620Ω) = 2.02V VAIN2 = IIDAC1 • RREF = 1mA • 1620Ω= 1.62V VINMAX = 1mA • 400Ω= 400mV 3. Verify that the design is within the range

As a rule of thumb, 3-wire circuits can handle wire runs up to 100 feet. 4-wire circuit 4-wire RTD circuits not only cancel lead wires but remove the effects of mismatched resistances such as contact points. A common version is the constant cur-rent circuit shown here. Is drives a precise measuring current through L1 and L4; L2 and L3 measure

circuit, shown in Figure 4, is used to excite the RTD element. With this style of excitation, the magnitude of the current source can be tuned to 1 mA or less by adjusting RREF. The voltage drop across the RTD ele-ment is sensed by A3, then gained and filtered by A4. With this circuit, a 3-wire RTD element is selected.

In a 4-wire RTD configuration, two wires link the sensing element to the monitoring devise on both sides of the sensing element. One set of wires delivers the

However, many people using and specifying RTD's do not realize that 2-wire, 3-wire, and 4-wire RTD sensors can be used interchangeably with very little difference in accuracy. Normally a 2-wire RTD will lose accuracy due to the resistance in the cable, which can be thousands

These RTD sensors can be used in any 2, 3 or 4-wire application by selecting one of the two available wiring arrangements (see the wiring diagrams below)
