The LNR220A is an industrial-grade, level monitoring, controller with a control range of 0 ~ 200 meters. It is mainly used for controlling and monitoring the water level of tanks, containers and pressure vessels to ensure the safe and efficient operation.

The LNR220A employs two types of detection methods, including differential pressure and capacitive level sensors, to measure accurately detect the liquid level. The LNR220A also includes a low-power, continuously operating, pressure transducer that records pressure readings and displays them as either relative or absolute pressure values.

The main working principle of the LNR220A is that it uses differential pressure sensors to measure the level of a liquid at two different depths, one being the low-level point and the other the high-level point. The differential pressure reading is then used to calculate the pressure head, and this is used to determine the level of the liquid. It also uses capacitive level sensors to detect when the level of the liquid rises or falls, and to react accordingly. This allows the LNR220A to control the level of liquid automatically.

The core features of the LNR220A are its high accuracy and reliability. The pressure transducer is designed to operate accurately and reliably in temperatures ranging from -50°C to +150°C. It also utilizes advanced signal processing technology to ensure that accurate readings can be recorded even when the liquid level and pressure varying constantly.

In addition, the LNR220A also comes with a comprehensive set of output options including four independent analogue outputs, one digital output and an optional serial communications port. These outputs are designed to provide users with the ability to control various aspects of the liquid level controller, such as pump speed, flow rate, and other related parameters.

Overall, the LNR220A is a versatile, industrial-grade level monitoring and controller that is ideal for use in a range of industrial applications. It is easy to install and can be used to accurately, reliably and safely monitor and control the water level of tanks and pressure vessels.
