We are sure that you will be satisfied throughout its use
1. APPLICATION
The NIPRESS D-300 series pressure transmitters measuring pressure and converting it into voltage and
current output can be used in 2- and 3-wire systems. The wide choice of the models makes it suitable for the
most pressure measurement tasks whether relative or absolute pressure, static or dynamic measurement is
required. The series is available with two different accuracy classes.
The design of the transmitter, its overload capability and wide range of temperature and the possibility to
install the unit in any position allows their application in the most different industrial circumstances.

3. MOUNTING
Due to its small size and weight NIPRESS D-300 can be directly installed on
tanks, pipes, machines, etc without mounting device.
To provide chance for replacement of the instrument during operation the use
of closing armature is recommended. A simple ball valve will be suitable for
lower pressure and for higher pressure (above 6 bar g) a three-way blow-off
needle-valve can be suggested. With pressure measurements of medium with
temperature over 75°C, the application of condensing device would protect the
instrument against overheating and extends its lifetime.
Temperature of the condensation in the condensing devices (in the water
lodge) is practically only 10 … 20°C higher than the ambient temperature.
Using longer impulse tube its proper sloping for the necessary de-aerating and
emptying has to be ensured.
Measuring low pressure values in systems with substantial height difference
between the transmitter and place of measurement the hydrostatic pressure of
the medium in the impulse pipe should be taken into consideration. In the case
of outside installation the unit is supposed to be protected against rain or
splash water.
3.1 INSTALLATION
For mounting and dismantling SW27 open-end wrench should be used.
The cylindrical housing of the transmitter should not be gripped
and tightened with pipe wrench!
The plug-in electric connector can be unplugged after releasing and removing
its fastening screw. The connection insert can be pushed out by a screw driver
from the direction of the screw.
Pushing electric cable through the cable gland it can be connected to the
relevant points of the connector. Make sure that the cable gland and sealing
plate of the connector will be tight.
For the sake of noise suppression the transmitter housing is grounded. If the
grounding of the appliance with the pressure transmitter is appropriate no
further action will be needed. If not, the grounding should be performed.
