Applications

Tips: Types of Vacuum Gauges

Capacitance Manometers: These gauges measure pressure by detecting changes in capacitance between two conductive plates. They are highly accurate and can measure a wide range of pressures, from high to ultra-high vacuum.
Pirani Gauges: These gauges measure pressure based on the thermal conductivity of the gas. A heated filament's temperature changes with pressure, and this temperature change is used to determine the pressure. They are suitable for medium to low vacuum ranges.
Thermocouple Gauges: Similar to Pirani gauges, they measure pressure by detecting temperature changes in a heated filament, but they use a thermocouple for the temperature measurement. They are effective for medium vacuum applications.
Cold Cathode Ionization Gauges: These gauges use an electric field to ionize gas molecules. The resulting ion current is measured to determine pressure. They are suitable for high to ultra-high vacuum applications.
Hot Cathode Ionization Gauges: These gauges use a heated filament (cathode) to produce electrons that ionize gas molecules. The resulting ion current is used to measure pressure. They are used for high and ultra-high vacuum applications.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
