Magnetic Float Level Switch Manufacturers in India, Suppliers and Exporters in India
Apsan India Instruments is a prominent magnetic Float Level Switch Manufacturers in India, suppliers and exporters in India, providing dependable point-level sensing solutions for industrial tanks, vessels and liquid-handling systems. From our perspective, we focus on robust construction, application-specific material selection and reliable magnetic reed-switch operation for water, oil, chemicals and process liquids. Modern configurations can support single, dual and multi-level switching and can interface with PLC-based automation systems.
What Is a Magnetic Float Level Switch and Where Is It Used?
A Magnetic Float Level Switch is a point-level sensing device that detects a preset liquid level through the movement of a magnetic float along a guide stem. It is commonly used for high-level, low-level or multiple-level control without requiring continuous electronic level measurement. Our designs can be selected as a Float Type Level Switch, Magnetic Liquid Level Switch, or Tank Float Level Sensor according to tank geometry, liquid properties and switching requirements.
How Does a Magnetic Float Level Switch Work?
- Buoyant Magnetic Float Movement: Our switch uses a buoyant float containing a permanent magnet that moves smoothly with changing liquid levels.
- Hermetically Sealed Reed Contacts: Hermetically sealed reed contacts inside the non-magnetic guide stem provide reliable and protected switching.
- Non-Contact Magnetic Switching: The float's magnetic field actuates the reed contact without direct mechanical contact with the sensing element.
- Multiple Switching Signal Options: The switch can provide normally open, normally closed, or changeover signals according to application requirements.
Which Types of Magnetic Float Level Switch Are Available?
A well-known Magnetic Float Level Switch Manufacturers in India, we are providing the best quality Magnetic Float Level Switch such as:
- Top Mounted Magnetic Float Level Switch: We use a vertical stem and magnetic float for convenient installation from the tank top. It is suitable for single, dual and multi-point level control and can support modern PLC-based tank automation.
- Stainless Steel Float Level Switch: We manufacture stainless-steel configurations for demanding applications where corrosion resistance and mechanical durability are important. SS304, SS316 and SS316L construction options can be selected according to chemical compatibility and hygiene requirements.
- Side Mounted Float Level Switch: We provide compact side-mounted designs where top access is restricted or tank geometry requires horizontal installation. Magnetic actuation enables dependable point-level switching for equipment such as chillers, hydraulic systems and dosing units.
- Multi-Level Magnetic Float Switch: We configure multiple preset switching points for high, low and intermediate level monitoring. This approach supports automated pump sequencing, alarm generation and process interlocking in modern industrial systems.
