LS-763 side-mounted liquid level switch
Overview
The liquid level switch is mainly composed of a guide rod with a reed switch inside and a float with magnetic steel. When the float rises or falls with the measured liquid level/interface,the magnetic field generated by the permanent magnet in the float drives the reed switch to operate and realize the switch action. Since the reed switch contacts are completely sealed in glass filled with inert gas, no electric sparks are generated when the contacts are switched on and off, and the control is quite safe. It has a compact structure,high reliability and stability;simple adjustment,easy installation,long service life,explosion-proof,corrosion-resistant and other characteristics.

Installation and precautions
- Rotate the switch in the specified direction according to the end face mark to ensure that the side-mounted float can rotate up and down flexibly;2.For single-setpoint liquid level switches, N.O or N.C swtich forms, the float cross section can be inverted to achieve conversion.LSAZ side-mounted liquid level switch,N.O or N.C switch form, the switch can be rotated 180° according to the end face mark to achieve the conversion of the switch form.
Application
- The float liquid level control switch is used in civil construction,sewage treatment,water purification and other industries to measure the liquid level of oil,water, sewage, acid, alkali and other media in open containers and pressurized containers.For Liquid additioni(discharge) control and upper and lower limit alarm control, or automatic opening and closing of the pump,so as to achieve unmanned automatic monitoring drainage of the pump to ensure the safety of the pump.
- Liquid level switches are used in the field of household electrical appliances,fully automatic washing machines,water dispensers, water boilers,dishwashers,household and commercial heaters,liquid medicines,provide on-site indications,monitor liquid levels, control the start and stop of pumps or the switch of valves,or perform high and low liquid level alarms for liquids in sealed containers,storage tanks,open containers,pools,etc.
- Liquid level switches are telecommunication control devices for liquid level heights in automobiles and industrial equipment. When the liquid level reaches the set high and low positions,the electrical contacts of the liquid level switch are disconnected or closed. By connecting it to the electrical circuit,signal alarms or control of the liquid addition(discharge)solenoid valve and electric pump can be realized,thereby achieving the purpose of controlling the liquid level.
- Widely used in industrial steel rolling workshops.It is mainly composed of sedimentation tanks, sewage suction wells, filters,clean water suction wells, well pumps, and dosing equipment. The equipment that needs to be monitored mainly includes suction wells(water levels),water pumps,inlet and outlet pipes(water pressure,water flow,water temperature),filters,safety water towers and other equipment.
- Refrigerant overflow protection for agricultural equipment, refrigeration equipment,chillers,and refrigeration tanks.
- Applied to drinking water and water treatment,according to the change of water level, control the operation of water pumps or solenoid valves,and provide on and off signals.
