Beijiafu sensor LVL-A7-AR2A-E5V1-CG
The LVL-A7-AR2A-E5V1-CG is a vibration type liquid level limit switch produced by Pepperl+Fuchs in Germany. It is mainly used for liquid level detection and control in the field of industrial automation, and is suitable for safety critical applications such as overflow protection or dry operation protection of liquid media.
This sensor adopts the principle of vibration measurement. When the probe contacts the liquid, the vibration is blocked, and the device determines the liquid level status based on this and outputs a switch signal. Its design meets functional safety requirements and supports the use of signal on alarm in safety oriented systems, which can reliably alarm in case of faults or power outages, ensuring system safety.
Main technical parameters:
Supply voltage: 10.8... 45 V DC (short-term pulse can reach 55 V DC)
Electrical connection: E5 interface is used, supporting two-wire connection
Protection level: IP67, suitable for harsh industrial environments
Application examples: dry operation protection, overflow protection, container liquid level monitoring
Working mode: Safety oriented (signal alarm mode)
This model is structurally similar to LVL-A7-AG1A-E5V1-CG, LVL-A7-BG1A-E5V1-CG, and other similar models in the same series. The main difference may lie in material compatibility or certification standards, making it suitable for industries such as food, chemical, and water treatment.
