UQK-10~40 float level switch is applicable for the liquid level control of open or pressure resistant vessels. When the level at lower or upper limit position, switch will send alarm signal and shut-off the controlling pump or valve. UQKS (with self-checking) liquid level controller can detect the controller and system as the equipment in normal operation to ensure them running with safety.

The world‘s most reliable and practical tri-magnet driven switch with bistable memorization function is applied on the magnetic level indicator. The switch is mounted on the connecting flange, non contact with process medium, with high temperature resistance, explosion proof and shocking protection functions. Due to the tri-magnet coupling triggering switch, the float moves as level rises via the magnetic steel (the primary magnetic steel) on the other side through connection rod, its magnetic force line goes through the magnetic coupling interface of stainless steel flange and make the secondary magnetic elements reverse, and the tertiary magnetic steel reverses as the opposite orientation according to the second one, and then drive the switch via pushing lever.
