Reed / Micro Switches: Activate electrical circuits when the float passes by, used for point-level detection.
SPDT and DPDT versions are available. 

Reed chain transmitters: As the float moves with the liquid level, it activates the reed switches, creating
a resistance change that is converted into an electrical signal corresponding to the level. This signal can
be transmitted to a display, control system, or recorder for monitoring and control purposes. 

Magnetostrictive transmitters: They operate based on the magnetostrictive principle, where a magnetic
pulse generated by a float interacts with a wire inside the probe. This interaction causes a mechanical wave that travels
back to a sensor, determining the precise position of the float. The transmitter then converts this data into an electrical
signal that can be used for monitoring and control.
