Abstract
The utility model relates to liquid level monitoring technical field, proposes a kind of multi-liquid level regulation and control's liquid level switch, including shell and adjusting assembly;The shell upper end is equipped with display, the display surface is equipped with key and alarm indicator light, the shell surface is equipped with the aviation plug of the display electric connection;The guiding slide bar upper end is fixedly connected with the shell, the hollow of the probe rod upper segment is provided with guide groove, the guiding slide bar lower end is slidably inserted in the guide groove, the probe rod outer surface is equipped with magnetic float, the probe rod lower segment is built-in resistance sensor. By controlling the probe rod in the guiding slide bar surface sliding, the lifting adjustment of probe rod is realized, so as to monitor the different depth liquid level change of different container, meet the adjustable demand required by specific production, for user, just order one or two range can basically satisfy production demand, to reduce inventory and cost, also can simplify after-sales problem.
