What is the liquid level switch LS used for?
LS stands for liquid level interlock, LSL stands for low liquid level action, and S stands for solenoid valve.
LS is a liquid level interlock switch. Its function is to automatically stop or start the pump when the liquid level reaches a certain level, and stop the outward or inward delivery of liquid, which plays a protective role. This post was last edited by psw1420 on 2009-4-5 21:33 ]
LS is just a switch that triggers a signal to the control system when the liquid level reaches the set value. As for subsequent actions, it depends on the system design and has nothing to do with it. It can be an alarm, or it can be a chain to start or stop the pump, or it can be a chain stop device.
LS: It should be a liquid level contact switch. If the liquid level is low or high enough to reach this switch point, the corresponding interlock will be triggered.: For example, stop the pump or close the liquid level shut-off valve, etc. This post was last edited by laiquanchang on 2009-4-6 08:19 ]
S--represents switch or interlock. L represents liquid level. LS should be liquid level interlock handle!
