Ratio-Metric 2-Wire RTD application Advantage: •Very simple RTD connection. •IDAC generates the sensor excitation and the reference voltage. •Noise and drift of the Ref voltage are correlated and therefore canceled. •Only one current source no mismatch. •Up to 7 RTDs are possible Disadvantage: Voltage drop across the line resistance.

R3 is Resistance of third lead wire (Extension cable used to connect RTD) L1, L2 & L3 are extension cable leads Ω1 is the total resistance between lead wires L2 & L3 Ω2 is the total resistance between lead wires L1 & L2 If and only if the wire resistances R1 and R3 are equal you measure the true Pt100 resistance.

of feet long. The 3-wire RTD uses 1 additional wire and the 4-wire RTD uses 2 additional wires to compensate for the wire resistance. Generally speaking, field devices have inputs for 3-wire sensors to provide sufficient compensation of the wire resistance. However, by “pulling” 3 wires to a 2-wire or 4-wire RTD you can achieve the same

3 Wire RTD Description. In order to minimize the effects of the lead resistances, a three-wire configuration can be used. Using this method the two leads to the sensor are on adjoining

11/12/  · 2 – Wire RTD: 3 – wire RTD: 4- wire RTD: Low accuracy: Better accuracy than 2 -wire configuration: High accuracy: There could be measurement errors: Fewer errors: There won’t be any error: Less expensive: Less expensive than the 4 wire type: Very expensive: Connecting wires should not be lengthy

The RTD is simply a variable R. It will need to be connected as you would any other variable R. It will need to be part of a voltage divider from 5v, input and ground. You will need to use a suitable R from 5v to the RTC and input, to give a usable analogue read.
