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.

See section D for compatible meters.

See Specifications for fitting material and fill fluid options. 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

–
