At Australian Vacuum Services we can supply service and repair most major brands of vacuum gauges, drop the team a mail today we will let you know whats services we can provide.
Pirani gauge is the most common of all vacuum gauges for Pressure measurement, We have huge experience on all types of hot filament gauges. it was way back in 1906 Marcello Pirani invented the gauge.
Our Sydney based team is ready to help.
The penning or cold cathode pressure measurement type, is a more deep vacuum gauge ranging from 10-2 mbar to 10-7 mbar. As vacuum gauges go these units are very hardy if used in the correct pressure levels.
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).
