Float switches, also known as level or liquid sensors, provide precise monitoring of liquid levels in tanks, containers, and systems. In the world of industrial automation, they have become a proven technology. Whether it's preventing overfilling, triggering alerts for low liquid levels, or controlling pumps, our float switches offer a reliable solution. The main advantage of an adjustable float switch is that its position can be adjusted to customize the switch point or the level at which the switch is activated. This allows for flexible adaptation to different container sizes and liquid levels, making them excellent for projects where the OEM (Original Equipment Manufacturer) cannot determine the required switch points with certainty. Through precise adjustment and readjustment of the switch points down to the millimeter, individual needs can be optimally met.
The operating principle of a float switch based on a reed contact relies on the use of a reed contact as a switching element. A float switch consists of a buoyant body, also known as a float, which floats on the liquid level. The buoyant body is equipped with a magnet.
As the liquid level changes, the buoyant body moves up or down accordingly. When it reaches a certain level, the magnet approaches the reed contact. The reed contact consists of two ferromagnetic contact blades placed inside a glass bulb. These blades are separated by a small air gap.
When the magnet of the buoyant body reaches the reed contact, the magnetic field attracts the ferromagnetic blades and brings them together. This action closes the contact blades, completing an electrical circuit. This closed circuit can be used to send a signal, such as triggering an alarm or controlling a motor.
- Precision: Float switches offer accurate detection of liquid levels for precise control and regulation.
- Reliability: Their robust construction and high-quality materials ensure long-term and reliable operation, even in demanding environments.
- Easy Installation: Float switches are easy to install and can be seamlessly integrated into existing systems.
- Ease of Maintenance: Thanks to their robust construction, float switches require minimal maintenance, saving time and costs.
- Flexibility: There is a wide variety of models and designs to meet individual requirements and operating conditions. They can also be readjusted and have their switch points changed as needed.
In industrial automation, float switches play a crucial role in liquid monitoring. Whether in cooling and air conditioning systems, hydraulic systems, heating systems, or the food and beverage industry, our float switches enable precise control and regulation of liquids to ensure smooth operation and prevent potential damage.
Float Switches for Pump Control
Another significant application of float switches is in pump control. Our float switches monitor the liquid level and automatically control the pumps on and off. This ensures efficient pump operation and prevents potential damage.
Oil Level Monitoring and Control
In the machinery and automotive industries, monitoring oil levels is crucial for the smooth operation of engines and transmissions. Our float switches provide precise oil level detection and can be used to trigger alerts for low oil levels or automatically control oil refills. This ensures reliable lubrication and prevents potential damage to machinery.
Float switches find applications in numerous industries. In the food industry, they are used, for example, to monitor liquid levels in storage tanks and filling systems. In the chemical and petrochemical industries, they play a vital role in the safe handling of chemicals and preventing overfills. They are also used in water treatment, mechanical engineering, the automotive industry, and many other fields where precise liquid monitoring is required.
