3201 Lecture 1: Report on Dead weight tester
Document Summary
A deadweight tester is a device that calibrates pressure by calculating the weight of force divided by the area over which the force is applied. Deadweight testers fundamental the for pressure are primary accurate measurement. Deadweight testers are used to produce a test pressure the pressure exerted by a gas or to calibrate a variety of pressure instruments. from liquid in order. Dead weights are usually used for pressure gauge calibration as they come with high accuracy, so they can be used as a primary standard. There are various types depending on the application, and they are powered by oil (hydraulic) or air (pneumatic). Dead weight testers are measuring devices with a piston-cylinder design. They are the most accurate primary standards for calibrating electronic or mechanical pressure measuring instruments. They operate on the fundamental principle that p= f/a, where pressure (p) acts on a known area of a sealed piston (a), generating a force (f).
