PG7607™ Operation and Maintenance Manual

This manual is designed to be used in conjunction with the PG7000 Piston Gauges Operation and Maintenance Manual, to operate a PG7607 Piston Gauge.

PG7607 is identical in conception and features to a PG7601 piston gauge. PG7607 differs only in the piston-cylinder mounting post and the piston-cylinder module as PG7607 is designed to exploit a unique 50 mm diameter piston-cylinder. This manual covers the aspects of PG7607 that are different from PG7601.

To operate a PG7607, use the PG7000 Piston Gauges Operation and Maintenance Manual and follow the instructions and information applying to PG7601. Refer to this manual for details on the piston-cylinder mounting post and piston-cylinder module.

In PG7607, the CYLINDER rather than the PISTON floats and is rotated. When using the PG7000

Manual to operate PG7607, references to the PISTON of PG7601 apply to the CYLINDER of PG7607.

(CAUTION) is used in throughout the manual to identify user warnings and cautions.

(NOTE) is used throughout the manual to identify operating and applications advice and

additional explanations.

PG7607™ Operation and Maintenance Manual

1. INTRODUCTION

1.1 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.
