ANALOG OUTPUT CONFIGURATION
The device has a configurable analog output. You can configure it using the
NXperience
software (check the
section), and you
can define: the electrical pattern, the error mode and the excursion range of the pressure to be transmitted.
The electrical pattern can be selected between 0-10 V and 4-20 mA modes and the error mode determines the behavior of the analog output in
case of sensor failure, as shown in
Table 03
:

Table 03
– Behavior of the analog output in case of sensor failure
* Available starting with firmware version 1.20 and software version 2.0.6.02.
The excursion of the electric signal respects the values set in the configuration of the lower and upper transmission limits, which allows customizing
the differential pressure range. The factory setting also defines the upper and lower limits of the sensor as the maximum operating limits of each
respective model.
The device is factory set with the 4-20 mA electrical standard and the pressure unit in mbar. Any changes in the pressure unit configuration readjust
the values of the transmission limits to the operating limits of the device.
