Dead Weight Pressure Gauge Testers

Are used for calibration of pressure gauges and other pressure sensitive instruments over a wide range of pressure & is generally regarded as the most accurate method in calibration and is either used as a primary or secondary pressure standard

Operating Principle: When fluid Pressure generated by a screw pump acts on the bottom of a vertically free floating piston the force produced pushes the loaded free piston vertically upwards. The piston floats freely in its cylinder and the pressure in the circuit will be determined by the weights loaded on the piston divided by the effective area of the piston with corrections for value of acceleration due to gravity, air buoyancy, surface tension and datum level difference. Vacuum works on reverse principle.



Technical Specification  
Screw Pump is used to generate pressure in the circuit of adequate capacity & is operated by turning the handle; it permits easy & accurate setting of pressure.
Free Piston Assembly (made of HCHC steel for low pressure & Tungsten carbide for High pressure) are hardened, tempered, ground and lapped to accurate sizes with very fine surface finishing
Oil Reservoir provides a convenient storage for hydraulic fluid that must be added to the system to replace fluid which is lost during the testing processes.
Needle Valve for cutting-off oil-reservoir from high pressure circuit  
Set of Weights are directly marked in convenient values of pressure and easily stacked on the carrier weight. These weights are available in either kg/cm2, bar, psi Cbf/in² units (other units on request). Storage box provided. Incremental weights to provide smaller steps available at extra cost for all models mentioned below.
Gauge Connector of 1/2" BSP (female) union for connecting gauge to be tested. Other sizes of gauges can be connected by using adaptors.
Baseplate of sturdy construction provided with legs and leveling screws. The entire circuit is protected by a Sheet Metal Cover This instrument is supplied complete in all respects and in ready to use condition for the calibration of pressure gauges etc
