SW-11 Magnetic Switch
SW-11 Magnetic Switch is qualified with SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety (Ex ia IIC T6 Ga) and Flameproof Enclosure (Ex d IIC T6 Gb) explosion protection.
Imported high quality and high-power reed switch as core component, with aluminum-alloy housing. Qualified with SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety (Ex ia IIC T6 Ga) and Flameproof Enclosure (Ex d IIC T6 Gb) explosion protection.
SW-11 Magnetic switch can be categorized by its output method as SPST type and SPDT type. For the application, SW-11 can be categorized as overflow or dry-run for liquid level alarm and protection.
As the measured fluid level rises and drops, the magnetic float rises and drops as well, and when the permanent magnetic steel within the magnetic float moves close to the switch, it stimulates the attached switches, triggering reed switch’s status to change, and providing a signal back to the control system to realize the liquid level control.
The output of the switches can be configured with SPST or SPDT, and can be set as anti-overflow or anti-dry protection.
