LCA pressure switches @ Application Pressure switches are used to control pressure equipment with tanks, keeping medium pressure of an agent within fixed, defined limits. The LCA pressure switch is used for the automatic switching on and off of electric motors (pumps) working in hydrophore systems and compressed air systems, in places free from dust, gases and explosive or chemically active vapours. Manufactured in three type-sizes depending on pressure range (0.4 MPa - 0.8 MPa -1.1 MPa). LCA pressure switches are manufactured as mechanized three-line or single-line dual-break manoeuvre low-voltage ac switches. An LCA pressure switch is a variety of a normally closed contactor. Its base, body, movable and stationary jaws are made of glass fibre-reinforced plastic. Copper contacts have silver-cadmium oxide tips. The connector casing is made of polycarbonate. @ Advantages of the LCA: 0 pressure converting system, toggles and electrical elements guarantee reliability and durability proved throughout the decades that the LCA switch has been on the market, Q membranes used in the pressure switches manufactured by Hydro-Vacuum S.A. are resistant to contact with oil pollution in pressure control systems, which allows the application of LCA switches in industry, 0 LCA switch is characterised by its stability and setting repeatability thanks to the use of high quality elements, 0 transparent cap manufactured from fail-safe plastic - polycarbonate, enables control of technical condition of the elements as well as position of the switch contacts, 0 two dimensions of the assembly spouts G1/4 and G1/2 which allows for assembly in the majority of pressure installations, 0 production and control process is carried out by qualified staff and complies with quality management _ system ISO:9001. Each switch undergoes hydraulic kIJ TfiSSUT© T3ng6 and electric trial - with test voltage of 2.5 kV 0 24 month guarantee MADE IN POLAND All components as well as the LCA switch are assembled in Hydro-Vacuum S.A. mostly from elements manufactured by Hydro-Vacuum S.A.; remaining materials (screws, nuts etc.), are manufactured locally.
