    You will not be able to get a meaningful temperature of a filament with a contact method. The thermal mass of a filament is very low, contact with any object will cause the filament to equalize in temperature with the probe, thus you will not measure the correct temperature.

    See my response to this same question in your previous post. Please do not double post.
