Float and Level Sensor – FRN21112 Application Field and Working Principle

Float and level sensors, such as the FRN21112, are utilized in a variety of industries and applications, ranging from food processing, chemical plants, wastewater treatment, oil tank and other liquid level measurements. These types of sensors serve as the vital means of monitoring liquid levels and are ideal for applications with tight space constraints, harsh environments and corrosive liquids.The FRN21112 is an advanced, highly efficient, commercial grade float and level sensor ideal for commercial, residential, industrial and agricultural applications. This sensor utilizes a unique float/level design, providing precise accuracy and reliable performance. The FRN21112 is equipped with a wide range of features, including a temperature compensated internal monitoring mechanism and a durable, stainless steel body.The FRN21112 is a float and level sensor, with a bi-directional, adjustable, and proportional output signal. When the float is moved through the liquid, its buoyancy causes it to move with the liquid and vary a reed switch contact proximity. As the float is moved closer or further away from its position, its changes in proximity will be indicated by a varying, digital output signal that is proportional to the changes in the proximity. This type of sensor is compatible with a variety of different types of measuring devices and system controllers, making it ideal for use in most applications. For optimal accuracy and longevity of the FRN21112 float and level sensor, the sensor should be horizontally mounted, with the supplied lead and reed switch assembly protruding downwards into the liquid being monitored. This position ensures that the float is not hindered by any foreign objects, and that the float is positioned in such a way that allows it to move freely and accurately. It is important that the device is regularly inspected, as improper operation and incorrect mounting can lead to inaccurate and unreliable readings.It is important to note that the FRN21112 has been designed and certified to meet the applicable international and regional standards. These standards include CE Marking, UL Recognition, and C-UL Certification. This means that the sensor has undergone extensive safety tests to ensure that it meets the highest safety standards.In summary, the FRN21112 float and level sensor is designed specifically for measuring liquid levels within various applications. It is a reliable and efficient device, with a digital output signal that is proportional to the levels of liquid in which it is immersed. The sensor is certified according to the relevant international and regional standards and should be regularly inspected to ensure its accuracy and performance.
