Description: Float level switch is a simple structure, easy to use level control device, it does not provide power, no complicated circuit, it has a mechanical switch than the average small size, long life and other advantages. As long as the material used in the correct shape and nature of any liquid or pressure, temperature can be used, which in the shipbuilding industry, generating equipment, petrochemical industry, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. have been widely application. How it works: liquid level sensor magnetic reed switch by having an important and integral float, float within the magnetic material in a sealed non-magnetic metal pipe or plastic pipe set or more magnetic reed switch Catheter through a or more with magnetic float, and double-loop control using a fixed float and reed switch in the relevant position, the float rises or falls with the liquid using the ball close to the beginning of the reed contacts Resulting in open and shut action for level control or direction (when the float near the reed switch is turned on; leave the switch off) Specification: Material: PP polypropylene Product detailed size: bottom diameter: 25mm/0.98 inch height: 55mm/2.17inch line length: 500mm/19.69inch The float switch is made of stainless steel 304 and the circlip is made of 316L Working current : 0.5-1(A) Material : PP, 304, 316, PTFE Working temperature : 0-120 (C) Maximum temperature resistance: 120 (C) Working pressure : 0.5 (Mpa) Maximum withstand voltage : 2 (Mpa) Media specific gravity : greater than 0.8 Rated voltage range: 440V and below Package Includes: 1 Piece Float switch
