1. INTRODUCTION

1.INTRODUCTION

1.1PRODUCT OVERVIEW

The DHI Manual Pressure Generator/Controller for Hydraulic Pressure (MPG2-H) provides a compact and easy to use system for manually generating, setting and finely adjusting pressures between atmosphere and 200 MPa (30 000 psi) in closed volumes. MPG2 is a standard pressure generation and control component for working with DHI PG7302 piston gauges or liquid operated RPM4 reference pressure monitors. MGP2 and RPM4 are available as a single, integrated pressure calibration instrument designated E-DWT

The MPG2-H-HV has a larger displacement variable volume (7 cc rather than 3 cc) and is intended for applications with higher test volumes to reduce variable volume stroke needed to generate the desired pressure. The maximum working pressure of MPG2-H-HV is 100 MPa (15 000 psi). The MPG2-H requires less variable volume torque and adjusts pressure more precisely.
