产品描述

OMEGA’s PX2088S Series smart pressure transmitters maintain a specification conformance of at least 3σ 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.

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® communicator 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
    – Fill fluid
    – Isolator material
    – Module serial number
    – Transmitter software revision level
