Datasheet
The gas operated BL503 absolute pressure piston gauges as primary standards for absolute pressure and gauge pressure, with emphasis on obtaining the effective area from the piston cylinder dimensions and the mass in vacuum of the pressure balance floating element. It is designed to enable metrology and research institutes to realize and disseminate exceptional fundamental pressure measurements.
FEATURES
0.005% of reading accuracy
Pressure ranges is up to 20MPa
Three different piston cylinder units can be exchanged for different pressure
20kg mass set or optional 40kg mass set
Build-in motor to rotate the mass set
With dial piston position indicator
PT100 shows the piston temperature
Pirani vacuum gauge can accurately measure residual vacuum in bell jar.
The aluminum alloy base that has been processed as a whole ensures the assembly accuracy and operational flexibility of the system
All internal pressure fittings are made of stainless steel material to avoid rusting of key sealing components and frequent equipment maintenance
APPLICATION
Primary pressure standard in lab
Reference pressure measure in workshop
