Can strain cause temperature fluctuation with PT1000 sensors?

Just lately, during testing of our printer, I noticed temperature faults on two different PT1000 sensors of our pellet extruder. Since the sensor cables run over a length of 15 meters and since they hang from 4 meters height above the end effector, I started to wonder if occasional strain on the cables could affect the readings?
The other option is a partially broken cable, but I rather do not believe this is the case since the cables are new and the printer has been in testing for just over three weeks now.
Any experiences on this topic?
Also, is it possible to route the sensor signals through a regular low-resistance wire without disturbing the reading too much?

Not flaming/accusing, but I've definitely fatigue failed wires within 3 weeks of testing with poor routing choices and/or non-flexible wire choices.
"occasional strain" can fatigue fail wires.
I've also rectified that by using high-flex regular wire without noticeable issues. Just don't use CCA materials and you'll probably be fine.
