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 800MPa. 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

Q: What is the length of piston?
Generally, it is 50mm with exception of inserting part of piston seat.
Q: What is the temperature on the front LED of BL512 deadweight tester?
It is amibent temperature.
The front LED also show the ambient humidity.
The temperature and humidity sensor is located under the hydraulic base.
Q: How to measure the piston temperature of BL512 deadweight tester?
Generally, use a AA class PT100, contact the outside of PCU to read the temperature value.
Q: There is a small hole on the piston cylinder unit, what is it used for?
It is used to release the excess librucating oill of PCU system.
