FQS series cable float switchDetailed product description：

Characteristics of FQS series cable float switch:

1. There is no movable mechanism outside, so there will be no malfunction of being stuck by floating debris
2. The components in contact with liquids are made of plastic, which has excellent oil and acid corrosion resistance
3. Easy on-site installation, especially suitable for use in underground water tanks
4. No requirements for water quality, especially suitable for sewage treatment
5. With a wide range of movements, it is now convenient to adjust specifically
6. Adopting the principle of practical patented micro switches, replacing the old manufacturing process of reed switches and mercury switches, to avoid toxic mercury pollution to the environment or human mercury poisoning during future recycling
7. The improved voltage can reach DC24V, the current can reach 10A, and the service life is greatly improved, without the misoperation caused by the demagnetization problem of the original reed switch itself

Structure principle of FQS series cable float switch:
The following is the user manual for the old style reed switch principle:
The basic components of the float magnetic switch are composed of a float and wires, and the reed switch signaling component is completely hidden inside the sealed float
When the magnetic ring has been axially magnetized and its installation position deviates from the center of the reed switch, due to the thickness of the magnetic ring not being the same as the length of a reed switch, almost all of the short magnetic field generated by the magnetic ring passes through a single reed, and the magnetic field lines are short circuited. There is no attractive force between the two reed switches The reed switch contacts are in the open state, and when the hammer tightens the magnetic ring, it can be considered that the thickness of the magnetic ring increases accordingly. At this time, the reed switch contacts are in the closed state
Using the installation method as an example to illustrate the working process of liquid level detection When the liquid level is at the lower limit, the floating ball is placed upright and relies on its own weight to be located at the lower part of the floating ball. Therefore, the contact point of the reed switch is in a disconnected state. During the process of liquid level rise, the floating ball maintains its upright position due to the dynamic hammer being at the lower part, and its center of gravity remains basically unchanged When the liquid level approaches the upper limit, due to the support point and wire pulling the float, it begins to tilt towards the upright direction. When it crosses the horizontal measurement position, the moving hammer inside the float quickly slides up, causing the float to flip to the upright position, and at the same time, the reed switch contact is disconnected
By adjusting the position of the fulcrum and the length of the wire, the control range of the liquid level can be adjusted. Similarly, multiple float switches are set at different liquid levels to provide liquid level signals, which can control and monitor the liquid level
