The PBR 260 Compact FullRange
®
BA Gauge has been designed for vacuum
measurement of non-flammable gases and gas mixtures in the pressure range of
5×10
-10
... 1000 hPa.
It must not be used for measuring flammable or combustible gases in mixtures
containing oxidants (e.g. atmospheric oxygen) within the explosion range.
The PBR 260 is part of the Pfeiffer Vacuum Compact Gauges family and can be
operated in connection with the MaxiGauge™ measurement and control unit
TPG 256 A or with another evaluation unit.
Over the whole measurement range, the Compact FullRange
®
BA Gauge has a
continuous characteristic curve and its measuring signal is output as a logarithm of
the pressure.
The gauge functions with a Bayard Alpert hot cathode ionization and a Pirani
measurement system. In a defined overlapping pressure range, a mixed signal of
the two measurement systems is output. Above that range, a Pirani signal, below
that range, a hot cathode signal is output. The Pirani signal switches the hot
cathode measurement system on and off to prevent filament burn-out and
excessive contamination. The user can select among two switching on/off
thresholds.
