VMT-PP WP Top Mounted Level Switches

Top mounted level switches work on permanent magnet reed switch basis. The floats which

contain permanent magnets move freely between their stops rising or falling with liquid level

movement. Hermetically sealed within the tube are reed switches, completely isolated from the

medium. The magnet's field actuates the reed switch as the float moves while the

stoppers restrict overrun and prevent the reed switch returning to its original position. Stopper

positions should not be changed.
