3 Fluke Calibration P3000 Series Pneumatic Deadweight Testers Model P3000
P3000 Series Vacuum and Dual
Vacuum/Pressure Models
The combined vacuum/pressure models are
extremely versatile instruments providing
vacuum through 500 psi (3.5 MPa) capacity in
one unit. An optional built-in hand pump can
be installed to generate vacuum (90 %) through
300 psi (2 MPa).
P3000 Series Liquid Lubricated Gas
Operated Models
The Models P3031 and P3032 feature an oil
lubricated piston/cylinder assembly, which
ensures that the instrument is less susceptible
to performance issues caused by contamination
of the gas supply or the environment in which
the unit is being operated.
The supply gas, via the deadweight tester
controls, is introduced into the piston/cylinder
chamber. As the gas acts directly on the surface
of the oil, there is a rate-less transfer of pressure
within the system.
The instrument is designed to prevent
inadvertent over-filling of the chamber, thus
avoiding contam-
ination of the gas
system. There
is no physical
barrier between
the gas and oil
so there is some
“oil-mist” trans-
fer potential.
