Piston deadweight tester as the most important benchmark instrument, is mainly used to check other pressure gauge, is one of the benchmark pressure instrument, is also a benchmark price on the market at present the highest pressure equipment, our factory production of piston type pressure gauge are not limited to obtain national verification certificate, more focused on measurement using convenience, make high efficiency easier is our for the market positioning of piston manometer.
Piston pressure gauge is a basic pressure gauge.It is mainly composed of hand-operated pressure generator, standard piston measuring head, standard weight set, hydraulic system and various control valves.When the oil cup valve is in the open state, the system can be filled with media through the hand pressure generator (or pressure checker).When the oil cup valve is closed, the deadweight tester becomes a closed pressure system.The closed system is then controlled by a hand - operated pressure generator.
During the whole working process, the piston type deadweight tester will work stably according to the hydrostatic equilibrium principle.The pressure of the system changes as weights are added or reduced on the piston chassis.To balance the pressure of the system against the force of the piston chassis and its connecting parts and the total mass of the standard weight carried at the time, the piston chassis shall be lifted (lowered) to the specified position by the manual pressure generator.The system pressure in this state is a standard pressure value.
Obviously, this is the practice of pressure concept definition, and the accuracy of this pressure value will depend entirely on the effective area of the piston system and the quality precision of the special weight.If the sealing state of the system needs to be removed, the oil cup needle valve can be opened slowly after the system pressure is lowered to the initial position of the piston chassis by the hand pressure generator.
