The Pressurements P3800
Series is the culmination of
over 50 years experience in the
design and manufacture of pri­mary pressure standards. With
features and options designed
to improve accuracy, increase
reliability, and simplify opera­tion, the P3800 Series can be
used to calibrate virtually any
high pressure sensing device
including transducers, trans­mitters, gauges or pressure
switches.

Instrument base

The Instrument base includes
all items required for operation.
A high quality hand pump is
coupled to a 7 to 1 intensifier,
allowing the operator to easily
generate high pressure in the
system. An oil reservoir is
included so the pump to be re­charged when calibrating large
volume devices. A Test Station
is provided for connecting the
Device under Test to the P3800
Series. Adjustable feet and the
level vial allow the operator to
insure the instrument is level
to achieve the ultimate perfor­mance. A Piston Float Reference
allows the operator to deter­mine when the piston is in the
ideal, “mid float” position.

Piston/cylinder

The piston/cylinder is the
“heart” of the deadweight
tester. P3800 Series pistons
are manufactured from tung­sten carbide which provides
excellent long term stability,
durability, and extremely low
coefficients for temperature and
pressure.

Weight sets

Standard weight masses are
series 3 non-magnetic stain­less steel. Each mass is marked
with the serial number of the
instrument and the nominal
pressure value. Select either
psi, bar or MPa pressure units.
PressCal software can be used
to support additional pressure
units.

Gravity correction

Gravity varies significantly with
geographical locations. Each
instrument can be calibrated
to local gravity a no additional
cost. If unspecified, instruments
are calibrated to standard
gravity at 980.665 cm/s2.
