Agilent Varian FRG-720 Pirani and Bayard Alpert SINGLE Filament Replacement Sensor. Hot Cathode Ion, 760 to 3.8 X 10-10 Torr,
NW25 KF25 Flange.
Agilent Varian PN FRG720KF25RS.

This Agilent Varian Single Filament Replacement Sensor is for the FRG720 Bayard Alpert and Pirani Combination Gauge with a NW25 KF25 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 single filament sensor with the NW25 KF25 flange. This replacement sensor is for the FRG720 combination gauges only. Signal cables and pressure controllers sold separately on this website. Agilent Varian Part Number FRG720KF25RS. A complete Operating Instruction Manual and Spec Sheet is available for download in .pdf format below under AVAILABLE DOWNLOADS.
