Hydraulic Dead Weight Testers (Accuracy : 0.015% )

Description of Hydraulic Dead Weight Testers :

1.The working position of piston is monitored by displacement sensor, which makes piston gauge more    sensitive and accurate.

2. Low gravity center of loads , piston rotating steadily and pressure fluctuating obscurely too much.

3. Novel seal structure and excellent properties.

4. Pump, pressure regulator , valve and pipe can be used conveniently because of reliability, portability and perfection.

specifications of Hydraulic Dead Weight Testers :

1.wide range
2.Accuracy: 0.05%; 0.02% ;;0.01%; 0.005%.

Hydraulic Dead Weight Testers of  Operating Principle:

Fluid Pressure generated by a screw pump acts on the bottom of a vertically free floating piston. The force produced pushes the loaded free piston vertically upwards. The piston floats freely in its cylinder and the pressure in the circuit will be determined by the weights loaded on the piston divided by the effective area of the piston with corrections for value of acceleration due to gravity, air buoyancy, surface tension and datum level difference.
