The 61F-G4 AC120/240 is an industrial-grade butterfly two-position, single-action, combined float-level and on-off controller manufactured by Omron. It is ideal for controlling and regulating the levels of water, oil and other non-corrosive liquid materials in a variety of process equipment tanks and similar applications. The controller provides accurate and reliable operation in a wide range of pressure and temperature operating conditions, making it a valuable asset in a wide variety of commercial and industrial liquid level control applications. In this article, we will discuss the application field and working principle of the 61F-G4 AC120/240.

Application Field

The 61F-G4 AC120/240 is designed to be installed on liquid tanks with a float immersed in the liquid. As the liquid level rises, the float rises and actuates the attached switch. The 61F-G4 AC120/240 can be used to control any type of operation that is related to the rise and fall of the liquid in a tank, such as controlling pumps, valves and other equipment. The controller functions as an on-off switch and can be used in applications requiring an alarm when the liquid level reaches a certain level. It is also ideal for applications requiring automatic switching based on the liquid level. Examples of applications that use this controller are agricultural pumps, water-level alarms in swimming pools, oil-field pumping systems, industrial machines and wastewater systems.

Working Principle

The 61F-G4 AC120/240 works on the simple principle of float-level and on-off switching. It works in the following way: When the liquid level in the tank reaches a certain level, the float connected to the bottom of the controller moves up, actuating the switch and allowing a current to flow through. This current changes the action of the controlled equipment, meaning that it is either switched off or on. For example, if it is connected to a pump, the pump will start when the liquid level reaches a certain level and cease pumping when the level falls below the same level. The current can also be used to activate an alarm or trigger a higher or lower pressure level. This ensures that the float-level control operates exactly as required in the process.

Conclusion

The 61F-G4 AC120/240 controller is a convenient and reliable way to monitor and control the levels of water and other liquids in a variety of commercial and industrial applications. It is easy to install and maintain, and provides accurate control of the liquid levels in tanks. The principal of float-level and on-off switching is simple and efficient, and ensures that the proper levels are maintained for the operation of any device controlled by it. In summary, the 61F-G4 AC120/240 is the ideal controller for controlling and regulating liquid levels in process equipment and tanks.
