Product Description

Double Floating Ball Liquid Level Switch liquid level sensor  PP water level signal Alarm
Working principle of float switch:
Float switch is usually installed in a sealed metal or plastic tube, with one or more magnetic spring switches installed. After the reed switch is installed, one or more hollow float balls with circular magnets are fixed on the rod diameter through the tube, and fastened to the relevant positions of the magnetic spring with buckles, so that the float ball can float up and down within a certain range. The magnet inside the float ball is used to attract the contact of the magnetic spring switch, generating an on/off action signal to control the liquid level

Product features:
1. Multiple control points can be achieved, the control switch can be customized according to the liquid level position.
2. Using a magnetic spring switch does not require a separate power supply, and the magnetic spring contacts.
The lifespan can generally reach 2 million cycles
3. A single device can be used for multi-point control, which is relatively cheaper than other liquid level switches.
4. High reliability, low wiring cost, and easy installation
5. The specifications of the junction box are complete, including aluminum alloy, plastic, stainless steel, etc texture of material.
6. The finished product is made of stainless steel SUS304/316, which can be used for high temperature and high pressure.
The venue is also made of PP, PVC, PVDF plastic materials, which can be used for strong acidity and alkalinity place.
7. The protection level of the junction box is above IP-65.
8. This product is suitable for liquids with different densities, acidity, acidity, pressures, and temperatures.

Application scope:
This product is mainly used in household appliances (such as pure water machines, water dispensers, water dispensers, humidifiers, dehumidifiers, electric water heaters, air conditioning equipment, household tap water direct drinking systems, etc.), industrial equipment (such as air compressors, air coolers, drainage systems, lubricating oil systems), garden equipment, medical equipment, beauty and hairdressing equipment, aquaculture and industrial water purification, sewage treatment systems, automatic door control systems and other industries. According to the special needs of different customers and environments, products are available in various sizes and materials, and customization is also accepted.

Common faults and troubleshooting of float switch
Fault phenomenon, cause analysis and troubleshooting methods
Floating ball doesn't move
1, Liquid specific gravity is less than float specific gravity → reconfirm float specific gravity
2,Floating ball leaking → Contact our company to replace the floating ball
3,Foreign object stuck on floating ball → Remove foreign object
Floating ball action, but no signal output
1, Float position offset → Adjust float position
2, Magnetic spring switch damaged → Replace magnetic spring switch
Abnormal signal output, nearby magnetic field interference → Eliminate magnetic field
Signal retention, unable to recover, floating ball unable to return, foreign object stuck → Remove foreign object
There will be two signal outputs at one point, the buckle position will move → adjust the buckle position
If it is not the above fault, please call our company for technical personnel to answer.
