FEATURES : The instrument consists of a microswitch inside a cast aluminium box, covered by a flexible membrane of neoprene or silicon rubber. OPERATION : The device must be mounted so that the flexible membrane is exposed to the product whose level should be controlled in such a way that the product, if present, can press the membrane. When this membrane becomes covered up by the product, it moves under the product pressure, thereby working the microswitch. The device must be connected to control signal or to mechanisms driving the product transportation systems, like feeding, unloading ,etc. APPLICATION : Switch has a buoyancy which guarantees smooth, trouble-free operation under all conditions. The switch has double chamber and a final remoulding finish to make it absolutely hermetic. INSTALLATION : MODEL DLS-AL-ND (with neoprene diaphragm) or DLS-AL-SD (with silicon rubber diaphragm) level switch is used for indicating, controlling, and regulating the level of granulated or powdered dry materials with a grain diameter up to 30mm and a density of 0.3 to 2.5 g/cm3, flowing through a silo, hopper or conduit. INSTRUCTIONS AND MOUNTING : The device can be installed outside the container by making a hole on the wall, so that the membrane remains exposed to the product inside. Suspended by means of a tube, it can be also installed inside the container. Using adaptors, it can be installed in pipes and conduits. Wherever possible level switch should be mounted on vertical surfaces. By this means ,the product can flow freely downwards, and wrong indications are avoided. It can be mounted on surfaces with a slope of not more than 30degrees from vertical, provided that the product leaves the membrane thoroughly free when flowing along. If maximum levels are to be controlled, the devices must be mounted at such a height that the product overflowing the membrane can exert pressure on this membrane, working the microswitch.
