Thank you for choosing NIVELCO instrument
We are sure that you will be satisfied throughout its use!
1. APPLICATION
The NIPRESS D-400 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 even at high temperatures. The series is available with two different accuracy classes.
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. It is especially
suitable for pressure measurement of contaminated mediums and at the bottom (level). Standard pressure
transmitting fluid is silicone oil but on request unit with liquid acceptable in the food industry is also available.
Transmitters can be delivered with plug in display UNICONT PLK-501 enabling on site reading.

3. INSTALLATION
Due to its small size and weight NIPRESS D-400 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 pressures and for higher pressures (above 6 bar) a three-way blow-off
needle-valve can be suggested.
For measuring hydrostatic pressure for level the unit should be thread in a
stub at the tank wall possibly near to the bottom.
Using longer impulse tube its proper sloping for the necessary deaerating and
emptying has to be ensured.
Measuring low pressures 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 REGULATION
Depending on the medium measured, the medium may cause hazard to the
installer, therefore you should be wearing suitable protective clothing, gloves,
and goggles.
For mounting and dismantling SW27 or SW44 open-end wrench should be
used. Take care for the vulnerable flush face diaphragm.
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 should be 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.
Installation steps:
The specified tightening torques must not be exceeded!
Tightening torques:
1/4” BSP: max. 5 Nm; 1/2” BSP max. 10 Nm; 3/4” BSP: max. 15 Nm; 1” BSP:
max. 20 Nm; 1 1/2" BSP: max. 25 Nm.
Mounting steps for connections according to DIN 3852:
Do not use any additional sealing material such as teflon tape! Check the o-
ring is undamaged, it has a flawless and clean surface and seated in the
designated groove. Screw the device into the corresponding thread by hand,
and tighten the parts with a suitable torque wrench.
Mounting steps for dairy pipe connections (DIN11851):
Check the o-ring is undamaged, it has a flawless and clean surface and
seated in the designated groove.
Centre the dairy pipe connection in the counterpart. Screw the cup nut onto
the mounting part, then tighten it using a suitable wrench.
Mounting steps for Clamp and Varivent
£
connections:
Choose a suitable seal for the measured medium and pressure. Place the
seal onto the corresponding mounting part. Centre the clamp connection or
Varivent£connection above the counterpart with seal, then fasten the device
with a suitable fastening element (e. g. half-ring or retractable ring clamp)
according to the supplier’s instructions.
3.2 CONDITIONS OF SAFE OPERATION
Before device turn on, make sure the installation is complete, and there are
no visible defects. The device may only be used within the limitations
specified in the technical specifications.
The device connector must be installed in such a way that the IP20 level of
protection is always remain.
Ex ia certified transmitters can only be operated in qualified, certified and
approved galvanically isolated intrinsically safe Ex ia circuits complying with
the technical data and the device’s explosion protection marking.
The metal housing of the device must be connected to the EP network.

5. TROUBLESHOOTING
Fault Possible causes Fault detection / remedy
No output signal:
Connected incorrectly. Check the connections!
Conductor/wire breakage. Check all wires with cable tester!
Defective measuring
device (signal input).
Check the amperemeter (and its
fuse) and the analog input of the
signal processing unit!
Analog output
signal too low:
Load resistance too high. Check the value of the load
resistance!
Supply voltage too low. Check the power supply and
power /current on the transducer /
transmitter!
Slight shift of the
output signal:
Diaphragm of senor is
severely contaminated.
Cleaning with non-aggressive
cleaning solutions, soft brush or
sponge.
Diaphragm of sensor is
calcified or crusted.
It is recommended to clean
carefully and remove dirt.
Large shift of the
output signal:
Diaphragm of sensor is
damaged (caused by
overpressure or
mechanically).
Check the diaphragm of the
sensor, if it is damaged then send
the device back to the
manufacturer!
6. MAINTENANCE AND REPAIR
The instrument does not require regular maintenance. If necessary possible
dirt deposited should be cleaned off. All repairs will be carried out at the
Manufacturer’s premises.
