The Inverted Magnetron Pirani Gauges MPG400 und MPG401 has been designed
for vacuum measurement in the pressure range of 5×10
-9 … 1000 mbar.
The Inverted Magnetron Pirani Gauges must not be used for measuring flammable
or combustible gases which react in air.
The gauges can be used with the Single-Channel Controller VGC401, the
Two-Channel Controller VGC402 and the Three-Channel Controller VGC403 or
with another evaluation unit.
Over the whole measuring range, the measuring signal is output as a logarithm of
the pressure.
The gauge consists of two separate measuring systems (the Pirani and the cold
cathode system according to the inverted magnetron principle). They are combined
in such a way that for the user, they behave like one measuring system
