PRODUCT OVERVIEW
PG7607 is a special model in the PG7000 line of piston gauges. PG7607 is identical to PG7601 except
for its piston-cylinder and mounting post.
PG7607 was designed to exploit a unique 50 mm diameter piston-cylinder. With this piston-cylinder, the
piston is mounted in a fixed position in the mounting post and the cylinder floats and is rotated.
A controlled clearance pressure can be introduced into the mounting post allowing the piston diameter
and thus the gap between the piston and cylinder to be varied.
PG7607 is available on a limited basis and, generally, is only offered for use in national measurement
institutes or other laboratories performing fundamental research in pressure metrology.
This manual is intended to be used as a supplement to the PG7000 Manual. PG7607 is identical to
PG7601 except for its piston-cylinder and mounting post. To operate a PG7607, use a PG7000 Operation and
Maintenance Manual and apply the information on PG7601 referring to this manual for piston-cylinder and
mounting post information. Also keep in mind that in PG7607, the CYLINDER, rather than the PISTON, floats
and is rotated. References to the PG7601 PISTON in the PG7000 Manual apply to the CYLINDER of PG7607.
