Level switches
Level Switches
Level switches detect and indicate changes in liquid levels. They are suitable for monitoring or controlling liquid levels in tanks, pipelines, or even natural waters.
Level switches can be mechanical or electronic and operate on different principles, such as float, thermal dispersion, electrical, or optical sensors. They play an important role in industrial and technical environments.
Magnetrol level switches are designed for a wide range of applications, available in mechanical, thermal dispersion, optical, and ultrasonic versions. They can measure under a wide range of temperatures and pressures.
