The magnetic float ring or magnetic floating ball are made of plastic(NBR/PA/PP) or stainless steel, have a very high strength-to-weight ratio making them shock and abrasion resistant as well as capable of enduring a high water pressure. Additionally, the magnetic floats have a high resistance to many chemicals and are therefore an ideal solution in fuel tanks, oil containers or brake fluid reservoirs. Actuator magnet is contained within the magnetic floating ball or magnetic floating ring though partially exposed to the liquid material. Float size and shape are different as liquid level sensors are different.
Magnetic floats are attached to liquid level sensor, please consult BST Sensor for specific parameters.
stainless steel magnetic floats vs Plastic float ball
Magnetic float ball or floating ring serve a variety of purposes across multiple industries. They're essential for systems like boilers, oil fields, water management, and refrigeration, where liquid level control and measurement are critical. While both materials can sometimes be used interchangeably, most applications require one or the other.
plastic float ball are commonly used in sensors for light-duty, consumer-grade applications. They are often found in simple systems such as toilet overflow valves, sump pumps, and pool pumps. Due to their affordability, plastic float balls are a cost-effective solution for basic liquid level sensors in these types of applications.
However, for more demanding sensor applications, stainless steel magnetic floats are preferred due to their enhanced durability and ability to withstand extreme conditions. Stainless steel magnetic floats can endure significant pressure and a wide range of temperatures, both high and low. In contrast, plastic float balls in sensors can fail under extreme temperatures, such as in boiler feed systems, where they are at risk of melting and causing sensor malfunctions. In colder environments, plastic floats are also susceptible to cracking and breaking.
Plastic float balls are suitable for basic, low-cost sensor applications, stainless steel magnetic float balls are essential for more reliable and durable sensor systems, especially in harsh or chemically demanding environments.
Magnetic Floats in Liquid Level Sensors
Magnetic floats play a crucial role in the operation of liquid level sensors, which are simple yet highly effective liquid level switches. These sensors operate without the need for power supply or complex circuitry, making them ideal for applications across a wide range of industries, such as shipbuilding, petrochemical, food processing, generator equipment, and water treatment.
At the heart of the liquid level sensor switch is the magnetic float, which is a floating ball embedded with magnetic materials. The magnetic float interacts with a magnetic reed switch that is enclosed in an airtight, non-magnetic tube, typically made of metal or plastic. As the liquid level changes, the magnetic float moves up or down within the tube. This motion brings the float's magnet closer to or further away from the reed switch, causing it to open or close. The resulting action is used to control or indicate the liquid level, providing a reliable and efficient method for monitoring and regulating fluid levels without the need for external power sources.
FAQs of Magnetic Floats
How does a magnetic float ball system function?
A magnetic float ball system, often called magnetic levitation or maglev, operates by employing magnetic fields to suspend a magnetic float without any physical contact. These magnetic forces balance out gravitational pull and other external forces, enabling the magnetic floating sphere to hover effortlessly.
What is the purpose of a magnetic float in a switch mechanism?
A magnetic float within a switch mechanism works by incorporating a magnet inside a metal float ball that adjusts with fluctuating liquid levels. As the magnetic float moves, it activates or deactivates a switch, managing electrical circuits typically used in pumps or alarms to track liquid levels effectively.
What is a float ball and how does it operate in a valve system?
A float ball, such as a stainless steel floating ball valve or a polypropylene float ball, operates by leveraging buoyancy to float on a liquid’s surface. As the liquid level rises or falls, the stainless steel ball float valve moves, often linked to a mechanism like a valve or switch to control liquid flow or indicate level changes, commonly used in systems like a stainless steel floating ball valve.
Are stainless steel magnetic floats used in float balls magnetic?
Most stainless steel magnetic floats, particularly those crafted from 440-grade stainless steel, exhibit magnetic properties, contrary to common assumptions about stainless steel. While many float balls, including those in a floating ring magnet set or metal float ball designs, are magnetic, non-magnetic options like a pvc float ball or plastic float ball are available for applications where magnetism is undesirable. For those interested in purchasing, options like floating ball for sale or buy floating ball can be explored through floating ball suppliers or manufacturers, with pricing details available via floating ball price inquiries or floating ball factory resources. For visual demonstrations, a floating ball video can showcase the functionality of a magnetic floating ring or floating magnet rings in action.
