Description
The measured Pressure value is outside
the sensor limits and no longer
representing the true applied pressure
The analog output (4 to 20 mA) is frozen
to one of its Saturation limits between
High or Low and no longer represents the
true applied process.
This is not a device error, but it is
consequence of its configured working
range in relation to the dynamic of the
process measurement.
The sensor temperature is outside its
operational limits as specified in the
product data-sheet.
This is not a device issue but if its sensor
is subject to work at abnormal
temperature conditions for long time,
then the device components could
degrade affecting its accuracy and
reliability.
The measured process pressure is higher
than the acceptable mechanical limit of
the process connection elements.
When this condition occurs, there is the
risk to damage the transmitter and to be
dangerous for the personnel.
The 4 to 20 mA signal in output by the
transmitter is simulated by the user and
no longer represents the true applied
At least one of the following variables
produced by the transmitter is simulated
and doesn't represent the real calculated

2. the Sensor temperature value
3. the Scaled output value.

The applied/measured pressure

The temperature of the process
environment affects the pressure
In some situation, the device
installation could be the cause of a

Suggested action
The compatibility of

conditions has to be
checked. Probably a
different transmitter
type is required.

It could be required to
perform a new sensor

replacement.
A different installation
type could be also

e.g. use of remote seals.
The compatibility of the
