Dual float level switch in low-temperature liquid nitrogen environment

Dual float level switch – Risk assessment of brittle fracture under 196℃ liquid nitrogen conditions
Salt spray test duration for dual float level switches

The salt spray test of the dual float level switch is based on GB/T10125-2021 and ISO9227 neutral salt spray test specifications, using a 5% sodium chloride solution and a 35℃ test environment. It is divided into four corrosion resistance levels according to the usage environment, corresponding to different test durations.
