This is very difficult. I have tried to restore my thermocouple by opening up the metal envelope and trying to separate and insulate the wires with Kapton tape, but failed. The ceramic body is very vulnerable to mechanical stress. Also there is not much room for additional material inside the sensor. This simply didn't work.
I am now switching to the EPCOS-thermistor i have laying around from my first E3D hotend.

Jep. The isolation of the wires in the sensor is open. They make sporadic contact to the metal hull that envelopes the ceramic body. I am trying to fix this with kapton tape, but I will need a new one.
