Working principle of floating ball liquid level switch

1, working principle: float level switches are basically reed switch structures, with a movable float outside and a magnet inside. When the magnet is buoyant and close to the reed switch, the contact in the reed switch is turned on or off;

2. The principle of reed switch is that like magnetic poles repel and opposite magnetic poles attract. The reed switch in the liquid level switch controls the corresponding operating mechanism to form a complete circuit.

Introduction:

1, the float level gauge consists of a float and a plunger;

2. The floating ball level gauge is installed on the top of the container through the connecting flange. The floating ball floats on the liquid surface according to the principle of equal volume of replacement liquid. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry spring of the floating ball level gauge is magnetically attracted, and the liquid level position is converted into an electrical signal, and the actual position of the liquid is digitally displayed by the display instrument, so that the floating ball level gauge can realize remote detection and control of the liquid level.

3. Technical advantages of floating ball level gauge: The floating ball level gauge has the characteristics of simple structure, convenient debugging, good reliability and high precision;

4. The float level gauge can be widely used for continuous liquid level measurement of high temperature, high pressure, viscous, dirty media, petroleum products such as asphalt, wax, flammable, explosive and corrosive media.
