Product specifications vacuum indicator IV:

 

The brightness of one digital digit of the indicator is not less than 100 cd / m2.

The filament voltage is not less than 0.8 ± 0.05 V.

The filament current is not less than 45 ± 55 mA.

 

The color of the glow for the products of the indicator lamp is green.

 

Vacuum-luminescent indicator is an electrovacuum triode of direct glow with a lot of phosphor-coated anodes.

 

    The work of vacuum luminescent indicators is based on the ability of some crystalline substances, called cathodoluminophors, to convert the kinetic energy of electrons to light. The vacuum fluorescent indicator is a triode with a positive control grid. The electrodes are enclosed in a cylindrical cylindrical cylinder, from which air is pumped out.
