Agilent Varian FRG-730 Pirani and Bayard Alpert DUAL Filament Replacement Sensor. Hot Cathode Ion, 760 to 3.8 X 10-10 Torr,
CF35 CF 2.75 inch Conflat Flange.
Agilent Varian PN FRG730CF35RS.

This Agilent Varian DUAL Filament Replacement Sensor is for the FRG730 Bayard Alpert and Pirani Combination Gauge with a CF35 CF 2.75 inch Flange. This filament sensor is replaceable by the user. 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.

This is the replaceable DUAL filament sensor with the CF35 CF 2.75 inch flange. This replacement sensor is for the FRG730 combination gauges only. Signal cables and pressure controllers sold separately on this website. Agilent Varian Part Number FRG730CF35RS. A complete Operating Instruction Manual and Spec Sheet is available for download in .pdf format below under AVAILABLE DOWNLOADS.
