PG7000 Piston Gauges

Reference Level Pressure Standards

 



INTRODUCTION

The piston gauge's fundamental operating principle and excellent long term stability have made it an indispensable tool in high accuracy pressure metrology. As accuracy levels increase, quality assurance requirements intensify and automation spreads through the workplace, the piston gauge must evolve to continue to fill its essential role in the measurement system. PG7000, the first truly new, high end piston gauge introduced since the late 1970s, responds to this challenge.

PG7000 development was undertaken with four main inter-related design objectives:

[1] Deliver real improvements in fundamental metrological performance to assure that today's
----- and tomorrow's ----- ever increasing accuracy requirements can be supported.

[2] Integrated automated monitoring of environmental and instrument operating conditions with extensive on-board intelligence to provide a modern stand alone instrument that outputs fully validated reference pressures, real time, through an intuitive operator interface.

[3] Reduce and when possible eliminate the influence of the operator on measurements to assure more consistent performance.

[4] Improve piston gauge ergonomics for greater operator satisfaction and increased productivity.
