AMH Automated Mass Handler for PG7000 series Piston Gauges

AMH Automated Mass Handler for PG7000 series Piston GaugesAMH Automated Mass Handler for PG7000 series Piston Gauges

Access to piston-cylinder module
The same piston-cylinder modules used in PG7000 with manual mass handling are used with AMH. The piston-cylinder module can be removed and reinstalled in less than 5 minutes, and requires about the same amount of effort as a single, manual mass handling calibration sequence.

The piston-cylinder module is accessed by removing the AMH mass handling system and masses. The procedure is to load all of the mass on the piston so that no masses are in contact with the mass handler. The mass handler is lifted off of the PG7000 platform vertically, leaving behind the complete loaded mass set. The masses are then removed manually to access the piston-cylinder module.

AMH-38, 38 kg under vacuum for PG7601
The AMH-38 provides automated mass handling of a 38 kg mass set for the PG7601 piston gauge platform. The mass handling system is integrated into a vacuum chamber which provides KF40 vacuum fittings for connection of a turbo molecular vacuum pump and external vacuum gauge if desired. Automated mass handling eliminates the need to break the vacuum between pressure points and reference vacuum as low as 0.01 Pa (< 0.1 mTorr) can be maintained indefinitely.

AMH-100, 100 kg for PG7102, 7202, 7302
The AMH-100 provides automated mass handling of a 100 kg mass set for the PG7102, PG7202 and PG7302 piston gauge platforms.

The 100 kg mass set results in a very wide range on a single piston-cylinder module, minimizing the need for piston-cylinder changes. A mass set of less than 100 kg can be configured if less than 100 kg is needed.
