Dead weight tester

Introduction  For the purposes of this section, we will define high-pressure instruments as devices that are capable of measuring pressures in excess of 10,000 to 20,000 PSIG (700 to 1,400 bars) One might group these sensors by other characteristics, such as: 1. Mechanical, such as pressure repeaters, helical bourdon tubes, or dead weight testers 2. …
