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
