Connection diagrams for RTD temperature probes and Thermocouples To ensure uniform wiring of all temperature probes, JUMO manufactures RTD temperature probes and thermocouples according to the Connection diagrams RTD temperature probes Thermocouples 2-wire 3-wire 4-wire 2x Pt 100 single double Standard LEMOSA connectors Terminal blocks 12 1

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.

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)

In this circuit there are three leads coming from the rtd instead of two. Red red white white red red white red red white black black yellow. Get Rosemount 3 Wire

Rpt is Resistance of RTD. R2 is Resistance of first lead wire (Extension cable used to connect RTD) R3 is Resistance of second lead wire (Extension cable used to connect RTD) L2 & L3 are extension cable leads. The wire resistances R2 and R3 are inevitably included in the measured value. Wire resistance can be cancelled by calibration, but just

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

In 4 wire RTD, the RTD has L1, L2, L3, and l4 lead wires. The current Is is the supply current from a known source and Eo is the output voltage for 4 wire RTD.

A typical three-wire RTD configuration. Sometimes, the two white wires in this image may have black insulation instead. Figure 2 schematic shows
