2 Flow switches SIKA has over 45 years of experience in the manufacture of flow switches for liquids. Our expertise in this field, which distinguishes us from other manufacturers, enables us to manufacture highly innovative products based on a modular concept. We offer flow switches to suit many applications and processes. SIKA is not only a market leader in this field, it has also pioneered the springless design concept. Numerous continuous and qualification tests over periods of up to 16 years testify to the quality of our products. Our range includes six standard series that can be co-engineered and tailored to suit specific customer requirements. Our extensive modular concept also includes a wide range of process connections with diverse pipe tees (inline) or different threads for direct installation (insertion). Our push-in version is the most innovative variant in our range. We modify our switches to suit all requirements regardless of the type of connection required. We also have a wide range of electrical connections with either nondetachable cable or connector. 6

3 Principle of operation The flow switch comprises a paddle system to whose end a permanent magnet is attached. Above this magnet is a reed contact, located outside the flow of fluid. A second magnet creates the force necessary to reset the switch back to the no flow position. When the flow being monitored pushes against the paddle system, the paddle swings away. This changes the position of the magnet in relation to the reed contact and actuates the switch. As soon as the flow is interrupted, the paddle moves back to its starting position, reversing the position of the reed contact. The force necessary to push the magnet back is provided by the two magnets repelling each other. Using magnetic force instead of the usual leaf spring means that the switch is considerably more stable in the long term and much less sensitive to pressure peaks. Paddle system Reacts to flow Magnet For activating the reed contact Reed contact Closes when flow starts opens when flow stops Pin Magnet For generating the paddle reset force 7

4 We offer flow switches in different materials to suit specific applications and demands. Whether highly rugged and sturdy of stainless steel for industrial applications or cost-optimised of glass fiber reinforced plastic for OEM applications our product specialists will be happy to help in finding a solution that best suits your application, both technically and economically. Customised serial versions can be provided with special factory-adjusted switching points. Advantages Low pressure drop Immediate response High repeatability Setpoint only dependent on flow, not on pressure or temperature Long-term stable setpoints as there is no spring fatigue 8
