Application Areas of Pressure Switch
Application Areas of Pressure SwitchPressure switches can generally be used in any application where electrical contacts must open or close in response to a system pressure change, within the electrical and pressure ratings of the switch. Pressure switches are used in a wide variety of applications such as the following:1.Compressed air systems 2.HVAC equipment 3.Pumping systems 4.Process equipment etc. Pressure Switches Used by All Kinds of Machinery (Including Food, Energy, Wood, Medical & Production Equipment) Food & Beverage Machinery: For example, pressure switches used to control the incoming water pressure of coffee machines that have a water supply with 3 bar and protects the system from overheating by switching it off if necessary. Another application that pressure switches are used is in Soda Jets up to 1500 I sparkling water with one cartridge of carbonic dioxide gas suitable for waiting areas in airports, shopping malls, gastronomy, offices etc. The pressure switch controls the incoming water pressure and shuts off the system if it exceeds the pre-defined setting. Other pressure switch applications for the food and beverage machinery industry include: 1.Aircraft Galley Equipment such as the water boiler and coffee machine 2.Dicing and Strip Cutting Machines - Capacity up to 1500 kg per hour. Pressure switches are situated in the valve manifold above the aggregate and are used to monitor and transmit pressure. 3.Monitoring Water Connections – Combination steamer roasts and stews simultaneous with controlled temperature and steam concentration. Energy Machinery Applications 1.Monitor pressure in gear boxes in wind turbines 2.Indicate fill level for intermediate pump mechanism with initial pressure tanks used by Municipalities potable water supply. 3.Monitoring pressure in Desalinations Plants and Reverse Osmosis Plants for brackish water. Wood Machinery Applications 1.Inside the manifold for the hydraulic unit of log yard machines that perform such tasks as butt-end reducing, debarking, measuring, cross-cutting, and sorting and the loading of logs. Medical Machinery Applications 1.Control incoming pressure for Ozone Analyzers (Hyperbaric Ozone Therapy) switching the machine off upon reaching the specified level or if safety sensor fails. 2.Monitoring of incoming pressure of medical oxygen before mixing with ozone in Ozone Generators. 3.Indicate interferences in gas pipe systems of Medical Gas Supply Systems 4.Control the bottle pressure of Anesthesia systems and the hydraulic lift control of the operating table. 5.Control the water pressure of the Variotherm Plus machine which is used for caloric examination of the vestibular organ by means of water. Production Machinery 1.Press Machines 2.Plastic Molding Injection Machines featured with hydraulic filter elements. Pressure switches are used to control the dynamic pressure. 3.Welding Machines 4.Paper Cutting Machines 5.Cold Forming Machines used for production of OEM parts (auto industry), Cylinder Head Screws, Surgical Instruments and Hydraulic parts to new a few. Pressure switches are used to measure hydraulic pressure that defines the end of a working process. 6.Industrial Pressing Machines for clothes 7.CNC-Machine – Pressure switches are used in the pneumatic circuit to control door movements, the position of the tools and the gripping devices. 8.Central Lubrication Systems –the Pressure switches are located at the end of the feed pipes of the central lubrication system. The switch will monitor the preset pressure point and signal the control unit that the lubrication process should be stopped. 9.CO2 – Laser Cutting (Gas Mixers) for CO2, helium and neon. 10.Continuous Ink Jet Printer – The pressure switch controls pressure for a safety function. 11.Jewelry Casting Machine – Pressure switches monitor the pressure in the information line for correct processes used in the casting process. 12.Cigarette Production Machines – is used to control the oil pressure and cooling liquid inside the cooling circuit of the electric motors and heat exchangers. |
