RELATIVE PRESSURE TRANSMITTER
– INSTRUCTION MANUAL – V1.0x F
INTRODUCTION
NP400 positive relative pressure transmitters are robust and reliable
equipment suitable for general industrial applications. They are
available in several measurement ranges and process connection
modes.
PRECAUTION
Before operating the transmitter, carefully read its specifications and
operating instructions. In case of damage caused by incorrect
operation or inappropriate usage, warranty becomes null and void.
The installation must be carried out by a specialized professional.
The electronic instruments power supply must come from a proper
instrumentation network.
UNPACKING
When unpacking, in addition to the transmitter itself, you should find:
•A quick guide to installation and operation.
•A sealed electrical connector.
•A screw to fix the connector to the transmitter.
IDENTIFICATION
An identification label is attached to the equipment housing. On this
label, you can found detailed information about the transmitter.

Installation recommendations
•The instruments must be powered from a dedicated
instrumentation power supply.
•It is strongly recommended to apply RC'S FILTERS (noise
suppressor) to contactor coils, solenoids, etc.
•To improve measurement stability, immunity and safety, it is
recommended to use system grounding.
