Sika level switches are the easy and reliable solution for monitoring fluid levels. The switches are installed at the side using G¾ or G½ thread sizes. The time-tested float principle and a potential-free contact as the signalling transmitter guarantee a high level of operational safety. The rising level in the tank forces the float up. Via paddle system, the magnet changes its position relative to Reed contact and actuates it. The repulsion between the two homopolar magnets and supports the buoyancy (Version VK... different). As soon as the level sinks again, the float follows also and the magnbet actuates the Reed contact again. Series VH level switches are made from brass or stainless steel and are available with different floats. Series VK level switches are made from plastic and are available with different floats.
