欧米茄的px2088s系列智能压力变送器保持至少3σ这些坚固的发射机性能可靠规范的一致性，再加上选择的广泛的选择，使这些传感器的艰难的过程应用的特殊价值。该px2088s设计在损坏或故障的传感器膜片的事件的**操作。电子舱是由2个密封件从过程分离
三分之一密封隔离现场终端和管道的条目。这种设计确保对住房加压过程污染。
电子集成ASIC模块接收数字信号从传感器，随着修正系数，并与线性化信号。这是然后转换为模拟信号传输。输出部还负责HART?通信。
智能功能
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
