Datasheet

The model BL511 hydraulic deadweight testers are applicable in very wide variety of pressure calibration and measurement tasks. 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% of reading up to 0.01% 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

0.02%, 0.01%, 0.005% accuracy

Built-in filter in 400ml oil reservoir

Shows pressure regulator rod position

3.5 inch LED shows piston position, ambient temperature and humidity

Piston moving position indicator can be easily calibrated

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 /℃

Five year warranty for piston stability
