400 Series Level Switch
Brand: SOR IncThe float rides on the process liquid surface, precisely tracking liquid surface motion.
Rising liquid level lifts the float, sliding the attraction sleeve up inside the enclosing tube and into the magnetic field to actuate the electrical or pneumatic switch (signaling liquid presence).
Subsequently, falling liquid level lowers the float, drawing the attraction sleeve out of the magnetic field to deactuate the electrical or pneumatic switch (signaling liquid absence).
Float-type level switches are generally able to handle high-temperature applications, and sometimes prove useful for close interface detection.
Floats can operate up to two switching elements. Independent switching levels may be obtained with tandem floats.
