RELATIVE PRESSURE TRANSMITTER
– INSTRUCTIONS MANUAL – V1.0x A
INTRODUCTION
The NP400 relative pressure transmitters are robust and reliable
equipment suitable for general industrial applications. They are
available in several measuring ranges and process connection
threads.
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, warranty
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.
