In this step-by-step guide we will show you the process of properly assembling a type K thermocouple probe.

Materials and tools needed

In order to assemble a type K thermocouple you will need the following tools and materials:

Materials:

  • 1 x Type K mini connector
  • 1 x Type K thermocouple wire 
  • 1 x heat shrink tubing (shrink: 3:1, width: 3mm, length: 10mm)

Tools:

  • Phillips screwdriver (PH0)
  • Wire stripper

Assembly Guide

Step 1
Disassemble the type K mini connector using the screwdriver.

Step 2
Prepare the wire to be connected to the type K mini connector.

  • Remove the white protection ring and place it on the cable
  • Remove the insulation of the outer wire (blue insulation) using the wire stripper
  • Adjust the inner wires to fit in the type K mini connector
  • Remove the insulation (5-10 mm) of the inner wires (red and black insulation) using the wire stripper

Step 3
Connect the cable to the type K mini connector.

  • Loosen the screws in the Type K mini connector
  • Connect the red wire to the positive pole (+ plus)
  • Connect the black wire to the negative pole (- minus)
  • Tighten the screws in the Type K mini connector
  • Place the white protection ring in the type K mini connector and reassemble the lid
If you connect the wires the wrong way, you can change the polarity in the Data Editor. However, best practice is always to correctly assemble the thermocouple.

Step 4
Prepare the tip of the type K wire

  • Remove the insulation using the wire stripper
  • Join together the black and red wire by twisting them firmly around each other
  • Attach the heat shrink tube and heat it up carefully using a lighter so the exposed wire is entirely covered
Important:
Ensure the wires are twisted thoroughly and that the tip is fully protected with heat shrink tubing to not experience any measurement errors!
We recommend testing the thermocouple prior to on-site use.
