Liquid Level Sensor ND005

The NOIKE-AH Liquid Level Sensor ND005 Series   is designed for liquid level measurement and monitoring in industrial tanks, vessels, and storage systems. The series is available in analog output and switch output versions to meet different monitoring and control requirements.

The sensor converts liquid level changes into either a 4–20mA analog signal or a resistance/switch signal, which can be transmitted to secondary display instruments or centralized control systems for remote monitoring and automatic process control.

Working Principle

The Liquid Level Sensor ND005 Series uses a float mechanism to detect liquid level changes.

As the liquid level rises or falls, the float moves accordingly. Depending on the selected model, the level change is converted into either a 4–20mA analog signal for continuous measurement or a switch/resistance signal for level indication and control. The output signal is transmitted through cables to secondary instruments or centralized control systems.
