Operation Principle

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 surface. The buoyant body is equipped with a magnet. When the liquid level changes, the buoyant body moves up or down accordingly. When it reaches a certain fill level, the magnet approaches the Reed contact. The Reed contact consists of two ferromagnetic contact leaves placed inside a glass bulb. These leaves are separated by a small air gap. When the magnet of the buoyant body reaches the Reed contact, the magnetic field attracts the ferromagnetic leaves and brings them together. This action closes the contact leaves, completing an electrical circuit. This closed circuit can be used to send a signal, such as triggering an alarm or controlling a motor.

In industrial automation technology, temperature sensors play a crucial role as they are used for measuring and monitoring temperature in various processes and systems. They provide accurate information about temperature to enable corresponding control and regulation systems to react. Temperature sensors in industrial automation technology are often used in conjunction with process control systems to ensure the smooth operation of facilities and to maintain optimal conditions. They help in monitoring product quality, ensuring safety, and improving energy efficiency.

A temperature switch, specifically a bi-metallic switch, is a sensor designed to open or close an electrical circuit based on temperature. It utilizes a bi-metallic switch as a sensing element to detect temperature changes and initiate the switching process. The bi-metallic switch consists of two metal strips with different coefficients of thermal expansion that are connected together. When the switch is exposed to a specific temperature, the metal strips deform due to their differing rates of expansion. This deformation results in a mechanical movement of the switch. The temperature switch uses the bi-metallic switch as a sensor to monitor temperature. When the temperature reaches or exceeds the preset threshold, the deformation of the bi-metallic switch causes a movement that either opens or closes the electrical contact. When the switch is open, the circuit is interrupted, and no current flows. This can serve as a protective device, for instance, to prevent overheating. When the switch is closed, the circuit is completed, and current can flow, leading to the activation of a fan or heater, for example.
