  • Improved Vacuum Control for Food Packaging
    Modern vacuum regulators dramatically improve the repeatability and consistency of packaged food products.
  • Vacuum Motors
    or position samples, products, mirrors and sensors in a vacuum area (some of the most common requirements) has been accomplished with drive mechanisms and motors located outside the vacuum chamber. In this type of control solution, the drive mechanism transmits its motion through the vacuum chamber
  • Motion Control and Precision Positioning in Vacuum Environments
    Vacuum applications are of growing importance due to technologies that can only be applied in vacuum or cryogenic environments.
  • Saving Energy with Intelligent Vacuum Technology
    It is a dry, oil-free vacuum pump, which can run with pressure control or at a constant rotational speed, making it exceptionally energy-efficient. The COBRA PLUS can thus precisely maintain the desired pumping speed at a prescribed rotational speed. It can also accurately sustain the required
  • Vacuum Brazing of Aluminum Cold Plates and Heat Exchangers
    metal. The filler metal, also known as a braze alloy, is drawn into the closely mated parallel surfaces of the aluminum plates by capillary action. The attributes of the vacuum brazing process include uniform heating, tight temperature control, no post cleaning processes, and process repeatability.
  • Butterfly Valves in Compressed Air & Vacuum Services
    Because a butterfly valve uses a disc to control flow, much like a damper in a duct system, some people occasionally want to use it to control the flow of compressed air and other gases, or for vacuum service. Will it work in these no-liquid applications? For the most part the answer will be yes
  • Vacuum Carburizing Furnace Cooler
    Project Goal. Provide pumping station, heat exchanger, chiller package and control panel that meet specifications all within the limited size available on the factory floor.
  • Evolution of the laboratory vacuum pump
    loborotory pump. However, if one $udies the evolution of fie loboratory pump over the po$ 25 yeors, il. becomes opporent thot this is an oreo of significant innovotion, with importonl developments. in high vocuum lechnology, corrosion resistonce, vocuum control, ond improvements in the. efficiency
  • Vacuum Permeation In O-Ring Polymers
    Permeation, or the permeability coefficient, of a polymer refers to the volumetric flow of gasses, under controlled conditions, through the material's surface. Permeability does not equal leakage! Leakage refers to gasses that flow around the seal. Permeation is a fundamental property of elastomers
  • Speed Control of AC and DC Motors
    There is a wide range of appliances that are part of our lives, from household electrical appliances used in the home like vacuum cleaners and hair dryers to pumps, conveyor belts, and machine tools in large industrial plants. Wherever any machines use electric motors some type of motor speed
  • Low-Cost Electric Range Control Using a Triac
    at the factory. * They have poor simmer performance (control is not precise at low temperatures). * The accuracy of these devices is poor. * Mechanical components wear out over time. This application note will describe a low-cost microcontroller-based replacement for the mechanical thermostat which
  • PI HV / UHV Motorized Stages: Vacuum-Compatible Positioning Solutions
    In order to maintain precision and reliability- the two key factors to the success of industrial processing - motion and positioning equipment has to be designed accordingly. These properties are entwined in ongoing quality assurance and process control. Reliability is key for any industrial
  • Electronics Plant Protects Sensitive Valves Using High-Performance Vacuum Cleaner System (.pdf)
    The continuous clean-up of plant equipment and products in an electronics manufacturing facility is a difficult task, especially when different areas of the plant have specialized cleaning needs. In controlled production areas, for example, it's critical to capture all dust and debris - even
  • Chemical Feed, Chlorination / pH Control
    REQUIREMENT:To provide bubble-tight shut-off of corrosive chemicals under high vacuum conditions.
  • Variable Leak Valves: Precision Leak
    All-metal ULV series precision ultrahigh vacuum leak valves are designed to control gas admission into high and ultrahigh vacuum systems. They are manually actuated via a cantilever arm fitted with extra-fine pitch threads for precise adjustment. They are ideally suited for handling hot
  • Metal Bellows - Key Enabling Technology for a Wide Range of Engineering Applications
    Versatile metal bellows play an essential role in controlling pressure, vacuum and motion, and more in a broad array of machine components and assemblies across numerous industry sectors
