Both one has been linked to be at ambient temperature during production.Provided in temperature sensor professional standard, the TEMP of Xin Ru factories
Device product, its resistance to pulling force standard is can be with resistance to 20N pulling force, but constantly undergoes cold and hot change in use, and its housing will
Come off；
2nd, water inlet failure：Epoxy resin and the insulating materials PVC of the cable material that to be also two kinds different, become repeatedly cold and hot
Under change, gap also occurs with PVC material in its epoxy resin, causes steam to enter pad, causes failure.To Xin Ru factories
Temperature sensor product, will use 100 DEG C of boiling water to be soaked, and be provided in professional standard, and immersion is not failed for 400 hours.
Actually many temperature sensor products do not reach the index of standard requirement.
