In the design of linkage float level switches, multi-point control of one product usually means setting up multiple (reed) switches on a single linkage that correspond to different level heights. Each switch is mated to a magnet inside the float at a specific position to trigger action when a preset level is reached.
Theoretically, increasing the number of points of a level switch does not directly affect the sensitivity of its individual points, as each switch operates independently of the other switches and relies primarily on the interaction between the magnet inside the float and the reed switch. As long as the design is reasonable, the individual switches should be able to switch accurately at the corresponding liquid level.
However, in practice, if the connecting rod structure is too long or too many switches are too densely arranged, it may increase the mechanical stress and dynamic response time, which will indirectly affect the overall performance, especially in the case of strong vibrations or rapid fluctuations in the level measurement. In addition, the freedom of movement of the float and connecting rod must be ensured to avoid jamming or delays caused by multiple points.
Therefore, ensuring the design and manufacturing quality of the product, as well as selecting the appropriate model specification for the application, is the key to maintaining the good sensitivity of the linkage float level switch under multi-point control.
