Reliability of stainless steel floating ball level gauge (reed switch's)

reed switch is not suitable for temperatures above 1℃, because it will cause demagnetization. At the same time, it is difficult to combine well between the shell and the lead wire of reed switch because of different expansion coefficients, so even the high-temperature type can not withstand repeated temperature changes.

In addition, the working temperature of the instrument and the allowable ambient temperature are two concepts, which can be used if reed switch is not in direct contact with the medium. In addition, there are many structural forms of temperature switch, which are not limited to reed switch and floating ball. You can check it online and choose one by comparison.
