Replacement PT100B sensor not shielded

Posted · Replacement PT100B sensor not shielded

Hi,

I bought this PT100B sensor as a replacement part for an UM2 and it looks different to the original sensor.

As you can see from the image, the leads are not shielded.

Just wondering if this would cause an issue with accuracy since the leads run in parallel to the leads of the heater cartridge and fan cables which might couple some noise into the sensor leads.

The part was ordered as a spare part from an official UM distributor.

Thanks for any feedback.

Flo

That is the PT100 that is installed on all UM2+ machines. It will work fine and it's an official part. You may have to adjust your temperatures slightly.

Thanks for your fast reply.

I'm using the sensor in an Olsson block as an upgrade (old sensor was impossible to get out without destroying it) so I will have to adjust temperatures anyway I guess.

Thanks again.

Ha! It seems impossible when you are frustrated but iRoberti can take out 99 out of 100 of these things. He has magic, genius techniques. My technique involves WD-40, 150C heat and a sewing needle.
