Dead Weight Tester
Dead Weight Tester
Dead weight testers are designed for calibration of pressure instruments. As primary standards, they are the most accurate and reliable instruments for calibrating electronic or mechanical pressure measuring instruments. In this, generally pressure instruments are calibrated against "calibrated weights". Dead weight testers are a piston-cylinder type measuring device. They 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 to 1200 kg, with single or duel piston type.
