Temperature fluctuation issue
Thread Content
One of the compressor bearing temperatures is fluctuating while the other is normal – is this due to the instrument? The fluctuation is about 2 or 3 degrees per hour
Generally, compressor bearing temperature sensors are installed in a one-main-one-redundant configuration. It’s not clear whether the person in question is referring to two thermometers for the same bearing or two different bearings. If it’s the temperatures of the same bearing, the problem is most likely related to the instrument itself; it is recommended to first check whether the sensor is functioning properly. If the sensor is defective, its replacement will require the assistance of a mechanical specialist
There are fluctuations in different positions of the same bearing. My question is: if the bearing temperature does indeed fluctuate, will the temperature change reflect that so promptly? Is it a genuine instruction or a fake one? Thank you
If the two temperature readings on the same bearing differ, it is likely a problem with the thermometers; however, it could also be caused by loose temperature sensing points. A thermometer should be able to reflect changes of 2-3 degrees per hour properly, but it’s abnormal when there is a difference between the two thermometers
Magnetic induction resistance can be used to measure bearing temperature
