LLC54BA Application Field and Working Principle

The LLC54BA is a type of liquid level controller that is ideal for application in environments and areas where a safe and reliable monitoring of liquid levels is needed. The LLC54BA is designed for use in industrial and commercial applications such as wastewater level and treatment systems, oil storage and management systems, and heating, ventilation, and air-conditioning (HVAC) systems.

The LLC54BA features a two-stage switch. This switch is designed to control the flow of liquid into or out of the vessel. The switch can be set to any desired level of the liquid, such as a set maximum and minimum. When the level of the liquid reaches the set maximum, the switch opens and the inflow of the liquid stops. Conversely, when the level of the liquid reaches the set minimum, the switch closes and the liquid re-enters the vessel.

The LLC54BA uses a combination of ultrasonic P2 and conductivity S3 sensors to accurately and reliably maintain the level of the liquid in the vessel. The ultrasonic P2 sensor transmits ultrasonic waves, which reflect off the surface of the liquid and measure the exact level of the liquid in the vessel. The conductivity S3 sensor measures the salinity of the liquid in the vessel and can be used to identify changes in the liquid level. Both sensors are housed within the LLC54BA, which reduces the amount of equipment necessary for its installation and simplifies the maintenance requirements.

The LLC54BA features redundant switch and multiple relay outputs which allows for multiple levels to be monitored in a single system. The output of the LLC54BA can be used to activate an alarm, open or close valves, activate and deactivate pumps, etc. The LLC54BA also features an LCD display which displays the level of the liquid in real time, along with the status of the sensors, switch and relay outputs.

The LLC54BA is a reliable and cost-effective solution for monitoring liquid levels in industrial and commercial applications. Its ultrasonic and conductivity sensors provide a high degree of accuracy and reliability, while its redundant switch and multiple relay outputs make it easy to monitor multiple levels in a single system. The LCD display on the LLC54BA also makes it easy to monitor the level of liquid in real time.
