The Granville-Phillips® 275 Convectron® Pirani Vacuum Gauges accurately measure pressure from atmosphere to 10-4 Torr. Every Convectron gauge is individually calibrated at the factory, making controller adjustment unnecessary.
To measure pressures above 10 torr with any confidence it is necessary to provide ambient temperature compensation. To maintain a constant temperature difference between the gauge filament and wall, a temperature-dependent resistor was wound on the tubular gauge envelope and included in the opposite ...
IMPORTANT With a Pirani gauge, you need to know the gases you are pumping and calibrate the gauge for those gases before you can measure true vacuum levels. The nominal 'V br vs. P' curve for the PG105 operated in air is shown in Fig. H-3. 0 1 2 3 4 5 6 0.001 0.01 0.1 1 ...
The AGP-1 provides a voltage signal proportional to the measured pressure. The high-resolution 16-bit voltage signal can be interfaced to a PLC, A/D converter, voltmeter or other readout devices. It is recommended to use a differential input to measure the output signal that uses a ...

The APG100 is available in two versions: the 'M' version can measure pressure down to 10-3 mbar and is suitable for general applications; the 'LC' version can measure pressure down to 10-4 mbar and is also suitable for use in corrosive applications. A general view of the gauge is ...
To measure higher pressures, the current control circuit was modified in such a way that the set value of the current increased in stages as the pressure increased. Further, it was ensured that the gauge showed high resistance to vibration and to an abrupt air intake as well as high radio...
