Dead Weight Pressure Gauge Tester

We offer dead weight pressure gauge tester
range - 0.5 to 25 kgcm2
for calibration of pressure gauges and other sensing, transmitting and recording pressure instruments. Relationship between pressure acting on the known area of a vertically free floating piston producing a force balanced by known dead weight is made use of in the dead weight pressure gauge tester.
The main components of a dead weight pressure gauge tester are:
1. Screw pump to generate pressure in the circuit. Of adequate capacity and operated by turning the spoked handle. Permits easy and accurate setting of pressure.
2. Free piston assembly of special steel, hardened, tempered, ground and lapped to accurate size and very fine surface finish to provide true floating action.
3. Set of weights directly marked in convenient values of pressure and easily stacked on the carrier weight. Available in eitherand kgfcm2, bar cbfin² units. Other units on request. Storage box provided.
