HIGH-ACCURACY
PRESSURE CALIBRATORS

OMEGA’s PCL341 and PCL342 set a new
standard for handheld pressure calibrators.
Both models have internal, isolated, stainless
steel pressure sensors with 0.025% FS
accuracy. For greater measurement capability,
an external connection supports all OMEGA
PCL-PM Series pressure modules. A Pt100 RTD
input allows temperature readings accurate to

0.1°C (0.2°F) (One Pt100 RTD probe comes with
the “-KIT” models). The PCL341 and PCL342
measure 4 to 20 mA loop current and up to
30 Vdc. An internal 24V loop power supply can
power a transmitter under test.

PCL340-030, $1099,

see page A-27 for

more information.

The PCL342 can display up to 3 measurements
simultaneously—for example, 3 pressure
measurements. The ability to display 2 pressure
readings along with an RTD temp makes the
PCL342 ideal for gas flow calibration (custody
transfer) applications.

The PCL341 is available in 9 ranges from
5 to 10,000 psig. The PCL342 comes in
2 standard ranges—15/1500 psi or
30/3000 psi—or the user can select 2 ranges
from 5, 15, 100, 300, 500, 1000, 3000, 5000,
or 10,000 psig. It also comes in a kit, which
includes the PCL342 pressure calibrator,
Pt100 RTD probe, 4 “AA” batteries, operator’s
manual, NIST-traceable certificate,
test leads, and hard-sided carrying case.
