CORROSIVE, AND NON-CORROSIVE MATERIALS

OMEGA is proud to feature state­of-the-art melt pressure transducers
for general purpose and precision
requirements. We also offer digital
indicator/controllers, thermocouples,
accessory cables, and connectors
for plastic extrusion.

Our transducers have been
selected for applications with
abrasive, non-abrasive, corrosive,
or non-corrosive material. They
offer a choice of 1% or 0.5%
accuracy, and they feature stainless
steel barrels in 3 lengths to meet
the space requirements imposed by
complex machinery, piping, and
insulation.

Models 330, 335, 340, 341, 370,

371. Offered in 88.9, 152.4, and

304.8 mm (31⁄2, 6, and 12") barrel
lengths, these transducers feature
a 17-4 PH stainless steel diaphragm
for melt pressure usage with
non-corrosive and non-abrasive
materials; ±1% FS non-linearity
(models 330, 340, 341) for general
purpose applications; ±0.5% FS
non-linearity (models 335, 370, 371)
for high accuracy; and a -17.7 to
399°C (0 to 750°F) operating range.

Models 350, 351, 380, 381 are
offered in 6" and 12" units with
Hastelloy C-276 diaphragm for melt

pressure usage with corrosive
materials such as PTFE, PVDF,
and fluorocarbon polymers. These
transducers also feature ±1% FS
non-linearity (models 350, 351)
for general purpose applications;
±0.5% FS non-linearity (models
380, 381) for high accuracy; and a

-17.7 to 399°C (0 to 750°F)
operating range.

Models 360, 361, 390, 391 are
offered in 152.4 and 304.8 mm
(6 and 12") units with hard chrome
plate diaphragm for melt pressure
usage with abrasive materials such
as fiberglass, aluminum, and cereal.
These transducers also feature
±1% FS non-linearity (models
360, 361) for general purpose
applications; ±0.5% FS
non-linearity (models 390, 391)
for high accuracy; and a -17.7 to
399°C (0 to 750°F) operating range.

Built-In Thermocouples.

Models with OMEGA’s
Type J (Iron-Constantan) or K
(CHROMEGA®-ALOMEGA®) high­accuracy thermocouples enable
simultaneous temperature/pressure
measurements up to 399°C (750°F).
These transducers are designed for
applications in which precision
control is critical and where space
for only one sensor is available.

Complete your transducer installation with
OMEGA®accessory hookup cables, PTFE
insulated for good abrasion and water
resistance. Or choose armored 0.275"
diameter BX cable for extra heavy duty.
OMEGA also offers standard cable connector
in order to make our transducers compatible
with your existing wiring. See order chart.
