What is a level gauge and a level gauge?

A level switch (also known as a level limit switch) is a sensor that detects whether the height of a solid material in a container has reached a certain position (usually an upper or lower limit).

A level switch (also called a level limit switch) is a sensor that detects whether the height of the liquid in the container has reached a certain position (usually the upper or lower limit).

Such sensors usually output a relay contact signal or an open collector signal, and the output signal is generally controlled in a chain sequence with a drive indicator, an alarm or an input PLC.


What is the level measurement?

Level measurement usually refers to the detection of the height of materials (solid or liquid level) in closed or open containers during industrial production; if continuous measurement of material height is called continuous measurement. If only the material height reaches a certain position, the detection is called limit measurement.
