Overview
KEY FEATURES
- Accuracy of LLR keeps same as ULR . That means one BL511 equals three other traditional DWT.
- The piston and cylinder is made of the high intensity, extreme hardness and lowest thermal expansion tungsten carbide.
- Pressure ranges up to 500MPa (75,000 psi)
- Piston/cylinder design provides stability and repeatability
- Visual indicator for checking piston location
- Modularized design, use friendly
- Customize local gravity value
APPLICATION
- Primary pressure calibration in lab
- Precision pressure measurement
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.
