Electric deadweight tester BL512

The model BL512 high pressure deadweight testers are applicable in very wide variety of pressure calibration and measurement tasks. The pressure ranges is up to 600MPa. The piston cylinder assembly is the heart of the dead weight tester and responsible for its high accuracy. We manufactures piston cylinder with accuracies from 0.05% up to 0.005% of reading. To give an idea of the manufacturing skills, the space between the piston and the cylinder is in the um range and can only be measured in a climate room. KEY FEATURES • 5MPa to 500MPa,…10MPa to 600MPa • 0.01%, 0.02%, 0.05% accuracy • With piston rotation electric motor • 3.5 inch LED displays piston location, ambient temperature and humidity • 400ml oil reservoir • 16mm thick aluminum alloy base • Piston position can be easily calibrated • Modulzied piston and cylinder unit • The piston and cylinder is made of the high intensity, extreme hardness and lowest thermal expansion tungsten carbide, which , density is 15 g/cm3, thermal coefficient of expansion is 16.5 ppm /℃ APPLICATION • Pressure calibration labs • Pressure measurement in field
