Thank you for choosing NIVELCO instrument

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.
