PRODUCT OVERVIEW
PG7000 Piston Gauges are reference level pressure standards that operate on the piston
gauge principle. Pressure is defined by balancing it against the force exerted by a known mass
accelerated by gravity on the effective area of a piston-cylinder.
A PG7000 piston gauge consists of the PG7000 Platform, one or several piston-cylinder modules, a mass
set. An automated mass handling system is available. A PG7000 system normally also includes the
means to generate and adjust pressures and to interconnect the system components and a device being
calibrated or tested. The pressure generation component can be manual or automated. COMPASS

Pressure software may also be included to assist in executing test sequences, acquiring test data and
producing test reports.
There are four PG7000 Platforms: PG7102, PG7202, PG7302 and PG7601. These have a common
PG7000 presentation and features. They are distinguished by their normal operating medium (oil and/or
gas) and the capability to define pressures relative to a vacuum reference.
•
PG7102 -
Gas operated with gas lubricated piston-cylinder modules (PC-7100/7600 modules)
-
Maximum pressure is 11 MPa (1 600 psi)
-
Does not support definition of pressure against a vacuum reference
•
PG7202 -
Gas operated, liquid lubricated piston-cylinder modules (PC-7200 modules)
-
Oil operated piston-cylinder modules (PC-7300 modules)
-
Maximum pressure is 110 MPa (16 000 psi) when operated with a PC-7200 module
-
Maximum pressure is 200 MPa (30 000 psi) when operated with a PC-7300 module
-
Does not support definition of pressure against a vacuum reference
•
PG7302 -
Oil operated (PC-7300 modules)
-
Maximum pressure is 500 MPa (72 500 psi)
•
PG7601 -
Gas operated, gas lubricated piston-cylinder modules (PC-7100/7600 modules)
-
Maximum pressure is 7 MPa (1 000 psi)
-
Supports definition of pressure against a vacuum reference
PG7000 platforms, piston-cylinder modules, mass sets and mass handling systems are designed to
maximize metrological performance and ease of operation. They include many features that enhance the
fundamental precision and stability of pressure measurements as well as simplifying use and reducing
operator influence on the measurements. Extensive monitoring and controlling capability and advanced
local and remote user interfaces are integrated into PG7000 Platforms.
Operator interaction with PG7000 and its extensive capabilities and peripherals is accomplished through
a single display and keypad on the PG Terminal or from a computer via a single standard RS232 or
IEEE-488 interface.
