Level switches are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action. These are typically point level switches, measuring whether the level of a container has reached or gone over a predetermined point. However, switching mechanisms can be integral to continuous level switches as well. Multiple point switches can be integrated together to give a stepped version of continuous level. These level switches can be used either as an alarm device or as control switches, turning something on or off, such as a pump, or sending a signal to a valve actuator. What makes level switches special is that they have a switched output and can be either electromechanical or solid state, either normally open or normally closed.

Dry Material (Powders) Level Sensing Devices
Dry material (powders) level sensing devices are used to measure levels of solid, dry materials in either continuous or point values represented with various output options.
Dry Material (Powders) Level Switches
Dry material (powders) level switches are used to measure levels of dry, solid materials via an electrical switching action.
Level Sensors, All Types
Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.
Level Transmitters
Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level.
Liquid Level Sensors
Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids. 
Liquid Level Switches
Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action.
