BalunTech BL502-250KPA-05 Pneumatic Deadweight Tester (5kPa ~ 250kPa, 0.005%)

Datasheet

With high precision accuracy, the model BL502 pneumatic deadweight tester is an ideal primary standard for defining the pressure scale in pneumatic range from 5 kPa to 10 MPa.   The piston cylinder assembly is the heart of the dead weight tester and responsible for its high accuracy. We process piston cylinder unit with accuracies from 0.02% up to 0.005% of reading. Because of the extreme hardness of this material, the pressure distortion (expansion) coefficient is negligible. The low friction coefficient provides minutes of turning with just a little swing of the masses.

FEATURES

0.005%, 0.01%, 0.02% accuracy

Accuracy of lower limit range keeps same as upper limit range.   

The piston and cylinder is tungsten carbide, which provides stability, durability, and low thermal coefficients and distortion.

Build-in pressure reduce valve and pipe

Big piston areas to meet high precision

High quality needle valves provide optimum control and sealing

APPLICATION

Primary pressure standard in lab

Reference pressure measure in workshop
