Agilent Varian FRG-730 Pirani and Bayard Alpert B/A Sensor Combination Gauge with Set Points. DUAL Filament, Hot Cathode Ion,
760 to 3.8 X 10-10 Torr, CF35 CF 2.75 in. Conflat Flange.
Agilent Varian PN FRG730CF35S.

This Agilent Varian Gauge is a Pirani and Bayard Alpert combination gauge, with set points. It has a hot cathode ionization design and contains a long life yttrium oxide coated iridium DUAL Filament. The gauge can measure pressure from 3.8 X 10-10 Torr to atmosphere. Over the whole measuring range, the gauge has a continuous characteristic curve and its measuring signal is output as logarithm of the pressure. The gauge functions with a Bayard-Alpert hot cathode ionization measurement system (for < 2.0×10-2 Torr) and a Pirani measurement system (for >5.5×10-3 Torr). In the overlapping pressure range of 2.0×10-2 to 5.5×10-3 Torr, a mixed signal of the two measurement systems is output. The hot cathode is switched on by the Pirani measurement system only below the switching threshold of 2.4×10-2 Torr (to prevent filament burnout). It is switched off when the pressure exceeds 3.2×10-2 Torr.

They have a CF35 CF 2.75 inch Conflat vacuum flange fitting. This is the FRG-730 gauge only, No display, No Profibus. User replaceable sensors, signal cables and pressure controllers sold separately on this website. Agilent Varian Part Number FRG730CF35S. A complete Operating Instruction Manual and Spec Sheet is available for download in .pdf format below under AVAILABLE DOWNLOADS.
