Low Cost Float Switches for Level Sensing
|
Comus International have now added to their extensive range of switch and sensor products a range of vertical and horizontal plastic and stainless steel floats. The range includes vertical and horizontal mounted single and multi float types including the side mounted crocodile type. The float switches are compact, reliable and very easy to install. They are not affected by electrical interference and with a wide range of materials are able to withstand various chemicals, high temperatures and high pressures. By varying the size of float and material used we are able to make sure the switch activities correctly every time. The activation of the switch uses the principle of a reed switch and magnet. When used in the vertical position the reed inside the stem is stationary and the float (housing a magnet) is moved up or down passed the reed switch (this closes the reed contact). When the magnetic field is moved away the reed switch opens. When used in a horizontal position the float is used in a pivotal movement. The magnetic field inside the float is moved into the proximity of the reed switch inside the stationary stem. The reed switch opens or closes. For more technical information on these and over 800 switch and sensor products please contact the sales office. |
