RELATIVE
PRESSURE TRANSMITTER – INSTRUCTIONS MANUAL – V1.0x F
PRESENTATION
The NP640 positive relative pressure transmitter series are robust
and reliable equipment suitable for general industrial applications. Its
great advantage is the possibility of a fast and easy configuration of
the operating range. With the aid of a software, the user has access
to the most important information of the transmitter and can set the
most appropriate configuration for the process.
PRECAUTION
Before operating the transmitter, carefully read its specifications and
operating instructions. In case of damage caused by incorrect
operation or inappropriate usage, and its consequences, the
guarantee becomes ineffective and null.
A specialized professional shall perform the installation.
A specific electrical power supply network should be provided for
instruments use only.
UNPACKING
After unpacking the product, besides the transmitter it must be
available:
•A quick guide to installation and operation.
•A sealed electrical connector.
•A screw to adjust the transmitter and the connector.
IDENTIFICATION
An identification label is attached to the equipment housing. On this
label, you can found detailed information about the transmitter.
Fig. 1 shows the identification label with their respective information.

Recommendations for installation
•Sensor signals conductors must go through the plant system
separate from power leads (loop), if possible in grounded
conduits.
•The instruments must be powered from the instrumentation power
supply circuit.
•It is mandatory the use of RC FILTERS (electrical noise
suppressors) in contactor coils, solenoids, etc.
•To improve the stability, immunity and safety of the measurement,
it is recommended to use the system grounding.
CONFIGURATION
When the transmitter is used with the factory setting, no further
action is required and the transmitter is ready to be installed.
When a new configuration is required, you should use the
Transmitter Configuration Kit. This kit includes the TxConfig-II
software, distributed free on our website, and the TxConfig-USB-
DIN43650 interface, which can be purchased in our distribution and
reseller network.
To install the TxConfig-II software, run the setup file
TxConfigIISetup.exe and follow the instructions of the installer.
The TxConfig interface must be connected to the transmitter
according to Fig. 3. The interface itself provides the electrical power
necessary for transmitter operation during configuration.

SOFTWARE CONFIGURATION
Fig. 4 – TxConfig II software main screen
When you run the TxConfig-II software, it will recognize
automatically the transmitter and will display the following
information:
1. General Information:
This field shows information that identifying the transmitter. This
information should be sent to the manufacturer in an eventual
request for technical assistance.
2. Unit:
Setting the pressure unit assumed for the measuring range
setting fields.
3. Measuring Range:
Setting the measurement range assumed by the transmitter.
Lower Limit: target pressure value for 4 mA current.
Upper Limit: target pressure value for 20 mA current.
Minimum Range
Do not set a lower band (span) that the Minimum Range
indicated below in this same field.
4. Sensor Failure: Sets the current output behaviour when the
transmitter experiences a fault:
Minimum: output current goes to < 4 mA
Maximum: output current goes to > 20 mA
5. Zero Correction: It corrects small deviations presented in the
transmitter output, when there is no applied pressure.
6. Send Configuration: It applies the new setup. Once sent, the
setup will be immediately adopted by the transmitter.
7. Read Configuration: Reads the current setup in the transmitter
connected. The screen now presents the current setup that may
be changed by the user.
