Float Switches with Bi-Metal Temperature Switch

Float switches with bi-metal temperature switches provide precise monitoring of liquid levels and temperature in tanks and systems. This technology is widely used in industrial automation to prevent overflows, trigger low liquid level alarms, and control pumps. By integrating temperature monitoring, these float switches ensure a reliable and efficient solution for a wide range of applications.

Functionality

The float switch, based on a reed contact, uses a reed switch as the switching element. It consists of a float with a magnet that floats on the liquid. When the liquid level changes, the float moves, and the magnet approaches the reed contact, which consists of two ferromagnetic blades within a glass capsule. These blades are separated by a small air gap. When the magnet reaches the reed contact, the blades attract and close the circuit, sending a signal, such as for an alarm or to control a motor.

The bi-metal switch, made of two metal strips with different coefficients of thermal expansion, detects temperature changes through deformation when a specific threshold is reached. This deformation triggers a mechanical movement that opens or closes the electrical contact. When the switch is open, the circuit is interrupted to prevent overheating. When the switch is closed, current flows, which could activate, for example, a fan or heater.

Advantages

Reliability: The 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.
Flexibility: There are a variety of models and designs available to meet specific requirements and operating conditions.
No Power Supply Required: Float switches are passive devices and therefore do not require a power supply.
Low Interference Factors: They are unaffected by foam, conductivity, dielectric, pressure, vacuum, temperature, etc.

Applications

Industrial Automation

In industrial automation, float switches are essential for the precise monitoring and control of liquids. Whether in cooling systems, hydraulic systems, or the food industry, they ensure smooth operation and prevent damage through accurate control. A central application is pump control: float switches monitor the liquid level and automatically switch pumps on or off, increasing their efficiency. In machinery and automotive industries, oil level monitoring ensures smooth operation and optimal lubrication of engines and transmissions.
