hi alls,
i want to make a simple vacuum readout unit in which the ionization
current from cold cathode guage is read by micro ammeter and then that
ammeter will be callibrated with some standard readout unit. if some
one has idea about this thing then i ll be very thank full to u for
helping me to solve my problem.
take care

We have these devices at work that are in our vacuumed systems for
cross linking irradiation process.
if you need a model number of a ready made receiver unit I can
get that for you how ever, if you want to construct something of
your own, you'll need to supply the spec's of the ion gauge probe
unit you are using..
The one's we use have a center tapped heater so that we can move
select the other spare heater incase it opens with out breaking down
the system.

hi,
thank you for your reply. and im sorry that i m very late to reply
your post. actually i was
busy in some other work. any how if you have some low cost vacuum
readout unit than
please gimme its model no. and other specs. than it is pleasure for
me.
as far as my ion guage is concerned than im using cold cathode guage
in the range of
10^-4 to 10^-8 mb. and i want to construct some readout unit which
will take ionization
current from cold cathode as an input and then i ll callibrate this
current for pressure with
some standard readout unit.
please gimme any idea about this problem.
regards
take care
