Advantages, disadvantages, and technical specifications of various level switches

Thread Content

Advantages of float level switches: Float switches do not contain components such as bellows, springs, and seals that can cause failures. Instead, a straight float is used to drive the magnet inside the switch, and the simple lever of the float switch causes the switch to act instantly. The float’s cant angle is limited to prevent it from becoming vertical. A float level switch is a level controller with a simple structure, easy to use, and safe and reliable. It is faster than ordinary mechanical switches and has a longer service life; compared to electronic switches, it also boasts strong resistance to load shocks, and a single unit can enable multi-point control. Easy to maintain. It is widely used in shipbuilding, papermaking, printing, generator equipment, the petrochemical industry, the food industry, water treatment, electrical engineering, the dye industry, hydraulic machinery, and other fields. Disadvantage: The float switch is a simple passive device that lacks self-checking capabilities; therefore, it is recommended to perform regular inspections and maintenance on it. Float or buoy level gauges have moving parts, so they get dirty when used in thicker or more viscous liquids. The measurement accuracy is poor; viscosity
