The Pressurements P3800

Series is the culmination of

over 50 years experience in the

design and manufacture of pri-

mary pressure standards. With

features and options designed

to improve accuracy, increase

reliability, and simplify opera-

tion, the P3800 Series can be

used to calibrate virtually any

high pressure sensing device

including transducers, trans-

mitters, 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 re-

charged 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 perfor-

mance. A Piston Float Reference

allows the operator to deter-

mine 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 tung-

sten 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 stain-

less 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/s
