Since it is a cold cathode discharge, there is no burning of the filament, its structure is simple and robust, and it does not cause a failure even when the switch is turned on at one atmospheric pressure.
The measuring sphere uses a special alloy for the magnet, is lightweight, miniaturized, and easy to handle.
Since there is no burning of the measuring ball filament, it can be easily used as a pressure indicator.
Application: Since it is easy to handle and robust, it can easily be used in a wide range of industrial instruments such as vacuum equipment.
