Fluke PG7000-AMH – Automated Mass Handler for PG7000 Piston Gauges

AMH technology
To install the AMH masses, a binary mass loading tray isplaced on the piston cap and a mass bell is installed over the tray. The mass set’s main mass discs are hung from the mass bell. Tubular binary masses are placed in descending sequence on the mass bell hanger and on the tray.

The mass handling system is placed over the installed mass set and controlled by the PG7000 platform, using RS232 communications from the platform’s COM3 port.

To load a specific mass value, the mass handling system raises the entire mass load above the piston upper end of stroke to the mass selection position. The mass is raised by a pneumatically actuated lifter acting on a lifter shaft connected to the binary mass spindle. Each tubular binary mass that is not to be loaded is held in place by engaging three selector pins. The three main mass columns are rotated synchronously so that the main masses not to be loaded are held in place by the columns’ retention ledges and masses to be loaded face release flats. When the mass selection is complete, the lifter moves down, placing the lifter shaft, binary spindle, bell and all the released masses onto the piston.
