Dead Weight Tester

Dead weight testers are the most accurate instruments for calibration of electronic or mechanical pressure sensors. Therefore they are used in factory and calibration laboratories in industry, national institutes and research laboratories. The measurement of the pressure by integrated pressure generation and the pure mechanical measuring principle is ideal for maintenance measuring instruments (e.g. visual high pressure cells). The core component of the model CPB5800 dead weight tester is therefore a very precisely manufactured piston-cylinder system, which is loaded with precisely graduated masses in order to generate individual pressure points up to 1,200 bar, with separator 700 bar. With a total measurement uncertainty to 0.006 % of the reading. [1]
