what is dead weight tester and where it is used?.
Answer Posted / vinod
Deadweight Tester (Pressure Balances)
are the most accurate instruments for the
calibration of electronic or mechanical
pressure measuring instruments. The direct
measurement of pressure, according to its
definition as a quotient of force and area,
and the use of high-quality materials result
in small uncertainties of measurement and
an excellent long-term stability of five years.
For these reasons, deadweight testers
have already been used in calibration
laboratories of industry, national institutes
and research labs for many years.
