Rosemount 2120D Liquid Level Switch

Rosemount 2120 Liquid  Level Switch is a non-contact liquid level measurement device that is highly stable and reliable. This switch is mainly used to detect the liquid level of liquid and solid materials in storage tanks, containers and pipelines to ensure normal operation and safe production.

Features

1. The 2120 liquid level switch adopts advanced radio frequency admittance technology, which has high measurement accuracy and stability, and can work stably for a long time in various harsh environments.

2. No need to rely on moving parts, which greatly reduces the failure rate and maintenance cost.

3. Suitable for liquid level measurement of various liquid and solid materials.

4. Support multiple installation methods.

5. It has a simple structure and installation method, which is convenient for on-site installation and maintenance. At the same time, it does not require regular calibration, reducing the cost of use.

6. With automatic diagnosis function, it can monitor the working status of the probe in real time to ensure the safe operation of the system.

Installation Precautions

a. It should be installed within the range of material-liquid level variation to avoid interference with other equipment. At the same time, choose the appropriate installation method according to the material characteristics, container shape and site environment.

b. During installation, ensure that the seal between the liquid level switch and the container is good to prevent leakage.

c. When making electrical connections, please ensure that the power supply, signal lines, etc. are connected correctly.

Rosemount 2120 Liquid level switch uses radio frequency admittance technology to enable liquid level detection by measuring the influence of liquid or solid materials on radio frequency signals. The probe on the switch generates a radio frequency field. When the liquid level rises on the probe, the impedance of the material to the radio frequency field changes. The resulting signal change is detected and processed by the receiver, and then triggers the corresponding alarm or control signal.

Parameter

Maintenance Precautions

a. Regularly check the appearance and connection of the liquid level switch to ensure that it is in good condition.

b. For materials that may have scaling, crystallization, adhesion, etc., the probe should be cleaned regularly to maintain good measurement performance.

c. When the liquid level switch fails, stop using it immediately, and find out the cause according to the fault code and deal with it.

d. When the equipment is shut down or not used for a long time, it is recommended to cut off the power of the liquid level switch to prolong its service life.

Disadvantage

a. For special environments such as high temperature, high pressure, and strong corrosiveness, other types of liquid level switches may be required.

b. When the surface of the material fluctuates greatly or there are interference sources such as agitators in the container, the measurement accuracy may be affected.

c. For non-conductive materials, such as certain oils, organic solvents, etc., the applicability of radio frequency admittance technology is poor.

Rosemount 2120 Liquid level switch can monitor the change of liquid level in real time, and send an alarm signal or control the change of liquid level when the liquid level reaches the preset value. It is suitable for the detection of various liquid media, including corrosive liquids and high-temperature liquids, and can be used with various control systems.
