Dead Weight Testers


Dead weight testers which is apparatus makes use of known traceable weights which is applied pressure to a fluid for checking the accuracy of readings from a pressure gauges and also is a calibration standard method which uses a piston cylinder on which a load is placed to make an equilibrium which has an applied pressure underneath the piston with which these dead weight testers are called as primary standards which means that the pressure which is measured by a dead weight tester which is defined through other quantities like that of length, mass and time. These dead weight testers are very much used in calibration laboratories to calibrate pressure which have transfer standards like electronic pressure measuring devices.

This instrument dead weight testers measures the pressure thus by balancing it with a piston of a known area which is fitted with weights and which works closely fitting vertical cylinder and as the pressure equals the total load it gets divided by the piston area. The accuracy and sensitivity of such a gauge very much depends on the accuracy of the piston cylinder and also by weights where even the friction is eliminated thus by rotating the piston and while taking readings. These pistons are made using hard and tempered steel which artificially aged. These are grounded and lapped to the size and also these cylinders are manufactured with equal care and the final assembly of the piston and the cylinder is very critically checked. Dead weight testers consist of piston which is mounted on a rugged base as its screw type operating system ensures an effortless operation and also rotation of these screw pump produces the pressure which is balanced by precision which weighs directly and which is marked in pressure units and are stacked on career weights.

Few types of these dead weight testers are motorized hydraulic dead weight testers and hydraulic dead weight testers which are very much accurate and stable as the pressure standards are widely used in the industry and are also available in single and dual piston types.
