How do you connect a Type J thermocouple?
To connect a Type J thermocouple:
- Identify the wires: The Type J thermocouple consists of two wires-iron (positive) and constantan (negative, a copper-nickel alloy).
- Connect the iron wire to the positive terminal of your measurement device or temperature controller.
- Connect the constantan wire to the negative terminal.
- Ensure proper polarity to get accurate readings-reversing the connections will cause incorrect temperature measurements.
- Use thermocouple extension wires made from the same metals (iron and constantan) if longer lengths are needed, to maintain accuracy.
- Make sure all connections are secure and protected from corrosion or mechanical damage.
