Profile: ATMI specializes in the manufacture of float and tilt level switches for liquids & solids. We are an ISO 9001:2000 certified company. We also manufacture external adjustable ballasts, cable clamps and intrinsically safe relays. Our Soba range floats operate by tilting as the water level rises/decreases, thus closing/opening a circuit connected to an electrical panel. These are supplied with appropriate adjustable ballast and guaranteed to operate for millions of cycles & have successfully passed electrical & waterproof tests before their commercialization. Our Bip Stop and AT float level switches are designed for the automatism of pumps and water storage/high level alarms with one single device. These floats simply open/close the pumps power supply circuit directly/through a relay. The distance between the float and the cable fixed to the pump sets the regulation height. Adjustable cable ballasts are usually necessary to ensure the proper operation of the float when the cable is hanging freely without any fixation. The ballasts enable the cable to stay well tightened and are actually the rotation point of the floats. Ballasts are meant to provide an accurate level regulation in still/agitated liquids. They also allow the float to operate in a wide range of densities.
