In dead weight tester,
we put the weight on the weight stand of dead weight tester
putting weight is reference weight which is to be calibrate
and further we applied pressure by moving piston ,when
applied pressure and reference weight(Pressure)is equal at
this condition reference weight willbe zero(Dead).
therefore it is called dead weigh tester.

Answer / kaushik

Dead weight tester is called dead weight tester because it
is working on dead weight principle that means there is no
variable parts in dead weight tester , Calibration and
Measurment done only based on simple dead weight principle
Weight = Pressure /Area

Answer / vijay

the dead weight tester is working on force balance
principle the force is depance on the weight.

Answer / gayathri

A deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.
The formula to design a DWT is based basically is expressed as follows :
p = F / A [Pa]
where :
p : reference pressure [Pa]
F : forca applied on piston [N]
A : effective area PCU [m2]
