NP620
RELATIVE PRESSURE TRANSMITTER – INSTRUCTIONS MANUAL – V1.0x G
PRESENTATION
The NP620 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.
