Lead wires are conductive cables that connect temperature sensors like thermocouples and RTDs to measurement instruments, transmitting electrical signals for temperature monitoring.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Resistance | Less than 1 ohm per 100 feet for RTD leads | |
| Bend Radius | 5× cable diameter minimum | |
| Conductor Size | AWG 20 to AWG 14 (0.5mm² to 2.5mm²) | |
| Voltage Rating | 300V to 600V AC/DC | |
| Temperature Range | -200°C to 1000°C depending on insulation | |
| Insulation Resistance | >100 MΩ at 500V DC |

Thermocouple extension wire is specifically alloyed to match the thermoelectric properties of the sensor, preventing measurement errors at connection points. Ordinary copper wire would create additional thermocouples at junctions, causing inaccurate readings.
Choose wires with appropriate insulation materials (like fiberglass or ceramic for temperatures above 500°C), consider thermal expansion compatibility, and verify the temperature rating exceeds your maximum operating temperature by at least 20%.
No, thermocouples require extension wires with matching thermoelectric properties, while RTDs need precision conductors with stable resistance characteristics. Using incorrect wires will cause significant measurement errors.
