Cable float switch series 1. Product introduction The series of cable float switches produced by Keyi Instruments are designed using the principles of gravity and buoyancy. They have a simple and reasonable structure and stable and reliable performance. The protection level reaches. It mainly includes a floating body, an internal large-capacity micro switch, a driving mechanism that can turn the switch on and off, and a three-core cable and weight connected to the switch. The distinguishing feature of this product is that it self-shields the influence of liquid level fluctuations (no malfunction caused by fluctuations in liquid level). At the same time, it is also non-toxic, corrosion-resistant, easy to install, low-priced, and has a long service life. The series of cable float switches can be matched with various liquid pumps and are widely used for automatic liquid level control in industries such as water treatment, water supply, drainage, water conservancy and electricity, and intelligent property management. 2. Working Principle When the liquid level is on the lower side of the buoy body, the buoy droops, the brown line (collinear) and the black line (normally open) are in a disconnected state, and the brown line and the blue line (normally closed) are connected when the liquid level When the liquid level rises, the buoy body follows and floats. When the rise is about 10 degrees, the brown line and the black line are closed, and the brown line and the blue line are disconnected, thereby achieving the control purpose. When the liquid level drops, the buoy body follows the descent until the buoy body is in contact with the horizontal line. When reaching about 10 degrees, each control point returns to the initial state. 3.
