Vacuum Gauges are used to measure low pressures, typically in the range 760 Torr to 10-9 Torr, in closed vacuum chambers.  Vacuum measurement forms a critical requirement for understanding processes happening in various instruments such as charged particle accelerators, surface analytical equipment, mass spectrometers, etc.

In order to cover the typical vacuum range of 760 Torr to 10-9 Torr, several gauges are usually employed, since there is no single gauge that can work over the entire pressure range mentioned.  This means that the vacuum chamber should have two or three ports for connecting different vacuum gauges covering different ranges and different electronic control units with respective cables for connecting the gauges to the control units.  This is a cumbersome task.

The full range vacuum gauge developed in Technical Physics Division, BARC, is a single flange mounted gauge that works over the entire pressure range of 760 Torr to less than 10-9 Torr.  Thus the gauge requires only one port in the vacuum chamber and only one electronic control unit. The gauge along with the special cable and electronic control unit are available for technology transfer to interested parties.
