WebDead weight testers are used to measure the pressure exerted by gas or liquid and can also generate a test pressure for the calibration of numerous pressure instruments. What does dead weight mean? Definition of deadweight. 1 : the unrelieved weight of an inert mass. 2 : dead load. 3 : a ship’s load including the total weight of cargo, fuel ... WebDeadweight testers define pressure based on a couple of assumptions. The two big ones are: 1. Piston cylinder temperature 2. Local gravity The pressure value determined by a deadweight tester is the result of summing the pressure values assigned to the loaded weights. Typically the weights will have a value stamped or engraved on them.
WebDeadweight testers operate by generating pressure through compression of the media inside the base. The goal is to establish equilibrium between the known reference … WebThe process of calibrating a dead weight tester is a complicated one, but on its most basic level it’s made up of a few steps. Primarily, this process includes a dimensional and mass inspection of the pistons and the weights used with it along with a verification of pressure. From there, our techs determine the effective area of the piston ...
