Dead Weight Pressure Gauge Tester
A basic standard calibrating device widely used in laboratories for pressure gauges is the hydraulic or pneumatically operated Dead Weight Tester. The Dead Weight Tester consists of accurately machined piston inserted in to accurately known cross sectional area coupled with oil reservoir and Pressure Gauge under testing fixing limb. Known weights in the form of discs can be loaded on the top platform of piston. The fluid pressure is then gradually applied on the piston un till the force is large enough to just lift the piston weight combination. When the piston is floating freely, the piston with arranged weights is in equilibrium with the pressure developed in the cylinder.
TechnoLab Dead Weight Pressure Gauge Tester is useful for students to study the calibration process of pressure gauges. It comes in to two ranges as
Range - 0.5 to 10 Kg/Cm²
Range – 0.5 to 25 Kg / Cm²
