Float type level switches come in many varieties, but have one common element. That is, they are all based on the principle of buoyancy. A float of certain volume and weight will be buoyant in fluids of a certain minimum density. This allows a switch to be incorporated and triggered at certain positions of the float.
Cable float type level switches may be the first that come to mind when someone mentions “float type level switch”. You might picture the activation mechanism of your sump pump in the basement of your home, the tank on your toilet or possibly the float type level switches used in the tank of waste materials at work. Either way, the cable float type level switch is only one of several varieties of float type level switches:
– Cable float type
– Side mounted float type level switch
– Magnetic float vertical level switch
– Compact or mini float type level switch
A cable float type level switch incorporates a switching mechanics, microswitch or reed type switch, inside of a float assembly usually constructed of durable polymer materials or stainless steel. The float element is attached to a prewired electrical cable of varying length. The cable float type level switch can be suspended inside the containment vessel by the cable itself or multiple cable float level switches can be attached to a suspension cable allowing multiple switch points with a single entrance into the vessel.
The other types of float type level switches are twists on the same basic principle. Sid mount units have a float element rigidly attached (not cable) to an enclosure that is used for mounting the level switch on the side of a tank. The name implies its primary use, side mounted on a tank or other vessel. These float type level switch units can use either microswitch or reed switch elements. They are typically made of stainless steel and can handle higher temperature, pressure and hazardous environments.
The float type level switch is reliable, cost effective and can be used in a wide range of applications.
