Having a big sale, on-site celebrity, or other event? Be sure to announce it so everybody knows and gets excited about it.
The Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems .It was invented in 1906 by Marcello Pirani
A thermocouple is an electrical device consisting of two dissimilar elctrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the thermoelctric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of thermal gauges but equally the effect can be used as a measure of vacuum.
Bourdon vacuum gauges is a mechanical device, which both measures and indicates and is probably the best known type of gauge. A vacuum gauge is a pressure gauge used in areas of vacuum from atmosphere to @ 1mbar.
Barometrically compensated hard shelled version are also available which are highly accurate to @1 %
The Spinning Rotor Gauge is a high-vacuum gauge that operates by measuring the amount of viscous drag on a magnetically-levitated spinning ball, which is directly related to the number of molecules in the chamber. It is commonly used for calibration and metrology of other high-vacuum gauge sensors such as cold cathode and hot-filament ionization tubes. Its accuracy specification of 1% of reading is guaranteed over the range of 1 x 10-2 Torr (mbar) to 5 x 10-7 Torr (mbar).
