Float, Level Sensors

Float and level sensing devices are used in a variety of settings from processing plant to general industrial applications. Often used to monitor liquids or solids, these sensors are categorized by their method of operation. Float and level sensors are generally divided into two broad categories: those that use buoyancy force to measure a level and those that measure the distance of a level within a given container. The LL01-5AA04 is an example of the latter type of sensor.The LL01-5AA04 is a submersible, chain-operated, level-sensing device that utilizes two measuring chains within a single enclosure. Through a series of linked components, the sensor is able to accurately measure the level of a liquid or other material within a given space. With a high level of accuracy and a low degree of maintenance, the LL01-5AA04 is a reliable solution for any steady liquid or solid level application. The LL01-5AA04 works through the conversion of the water or other material\'s pressure to a chain movement. This chain movement allows for a measurement of the level. The device uses four distinct components within its system - the pressure chamber, the chains, the chain terminals and the chain welds. The pressure chamber contains a sensitive diaphragm that allows for a measurement of the pressure within the tank containing the material to be measured. It then converts the common pressure measurement into a chain-driven tension which pushes the chains towards the tank’s deck. There is a finite amount of chain available and therefore when the tank\'s level rises or falls, the tension needed to overcome the force of the liquid’s buoyancy is affected. This chain tension ultimately creates the measurement of the level.The next component is the chains. Chained together, the links are composed of a stainless steel material that is corrosion resistant and can withstand both high and low temperatures as well as pressure changes. When combined with the pressure chamber, the chains will move in relation to the level of the material being measured. The third component is the chain terminals which attach to the two free ends of the chains. Designed to fit to the specific chain and pressure proof, chain terminals can be easily replaced, allowing for easy maintenance. Finally, the last component is the chain welds. By utilizing an inert gas, both ends of the chain are sealed together to prevent any water or other material from running into the chamber.As a result, the LL01-5AA04 is an accurate and dependable solution for any liquid, solids or other level sensing application. With a durable structure and high quality components, the LL01-5AA04 is sure to satisfy its users. With its ability to withstand variable temperatures, pressures and an impermeable seal, the LL01-5AA04 is a reliable and compelling solution for any level sensing application.
