PX2088S-30GI
analog transducer,
$1255, shown smaller
than actual size.
OMEGA’s PX2088S Series smart
pressure transmitters maintain a
specification conformance of at least
3. The reliable performance of these
rugged transmitters, when coupled
with the broad selection of options,
makes these transducers an
exceptional value for tough process
applications.The PX2088S is
designed to operate safely in the
event of damage or failure to the
sensor diaphragm. The electronics
compartment is isolated from the
process by 2 seals.
A third seal isolates the field
terminals and conduit entries.
This design ensures against
housing pressurization and
process contamination.
The electronics incorporates an
ASIC module that accepts the digital
signal from the sensor, along with the
correction coefficients, then corrects
and linearizes the signal. This is then
converted to an analog signal for
retransmission. The output section
also handles the HART
communications.

To order absolute pressure ranges, change the “G” in the model number to an “A”, and add
$215 to price. To order LCD meter scaled 0 to 100%, add suffix “-M5”, and add $250 to price.
Ordering Example: PX2088S-150AI, smart transducer, 150 psi absolute pressure range,
with 4 to 20 mA output, $1255 + 215 = $1470.

SMART FUNCTIONALITY
The PX2088S smart transducer
HART®protocol allows easy access
to configuration, test, and setup
capabilities.
The PX2088S can be configured
using a HART
or another HART®-based
communications device.
Configuration consists of
two steps. First, the transmitter
operational parameters are set
including:
– Zero and span
– Damping
– Engineering units.
Second, data can be entered into the
transmitter to allow identification and
physical description of the
transmitter. These data include:
– Tag: 8 alphanumerics
– Descriptor: 16 characters
– Message: 32 characters
– Date
– Integral meter installation
– Remote seal information
In addition to the configurable
parameters, the PX2088 software
contains information that is not userchangeable. Non-configurable
information includes:
– Transmitter type
– Sensor limits
– Minimum span
®
communicator
– Fill fluid
– Isolator material
– Module serial number
Transmitter software revision level
–
