Description :
Dead weight testers are designed for calibration of pressure instruments. As primary standards, dead weight Testers are used for the calibration of electronic or mechanical pressure measuring instruments. In this, Dgenerally pressure instruments are calibrated against 'calibrated weights'. Dead weight testers are a pistoncylinder type measuring device. Dead weight Testers work in accordance with the basic principle that P= F/A, where the pressure (P) acts on a known area of a sealed piston (A), generating a force (F). The force of this piston is then compared with the force applied by calibrated weights. Table Top Machines are engineered for a different working range up to1200kg, with single or duel piston type.
