A Liquid Level Switch is a vital component used in many industries to detect the presence or absence of liquid at a certain level within a container or tank. These switches are designed to trigger an alarm, activate a pump, or control other processes based on the liquid level. We have a diverse range of capacitive Level Switches tailored for refrigeration applications.

Features and benefits

• Tailored for industrial refrigeration: Our switches are built for industrial refrigeration applications, ensuring optimal performance and reliability without needing adaptations or modifications.
• Easy installation and diagnostics: The unique split design makes it easy to change the electronic part without evacuating the system.
• Wide temperature range: With a temperature range from -60°C to 145°C (-76°F to 293°F), our switches can operate effectively across a broad spectrum of temperatures, providing reliability in diverse operating conditions. It is also equipped with built-in heaters, most electronic units are suitable for wet and low temperatures, safeguarding against condensation and ensuring consistent performance.
